After thirty years of welding for a living I learned guys on KZbin know more about welding than professional welders.

[@dariopranckevicius1250]

Great tip on making the 45 degree “valley”! Makes a ton of sense!

[@LakesideAutobody]

Thanks - today's sheet metal is too thin to butt weld and grind flush. If you prefer butt, I really believe this is the way to go :)

[@bjr2379]

Friday night auto body and some bottom shelf bourbon. 🇺🇲👍🥃 When I was young my job was pushing the two pieces together with a screwdriver while my old timer friend brazed or soldered the panels. Then I had to cool it down with a wet shop rag.. Good times! We always put a thin coat of short strand fiberglass on first to help seal the joint and then put plastic filler on top. Great video!

[@LakesideAutobody]

Sounds like fun. The short strand fiberglass is a good suggestion.

This video came just in time! Fixing to do a cab corner and going to try the 45 degree trick. That is so helpful. Thank you for all the info and great videos!

[@LakesideAutobody]

You're welcome. You can use either method 45 (butt) or lap weld you patches. What ever is easiest for you. Both methods hold up well - moisture sits at the bottom not up where you welded. Good luck on you project. Here's one that was lap welded - kzbin.info/www/bejne/nIS3nIChhdeshrM

Dude you won a suscriber just in the part you mentioned using the pliers to make a 45` angle to make the weld more solid and easy, as we all know sheet welding is a samurai-like art that takes time to master. That little trick was awesome, without mentioning it improves the general mechanic resistance of the seam a little bit.

Great video. I have a question, can similar be done with creating a lip edge on the patch panel to go under the original and welding it similar to how the bottom was done?

[@LakesideAutobody]

There really are no rules so if it works for you then it is a quality repair. You just want to make sure that what ever method you choose works on absolutely everything so that you become efficient. The only problem I see w/ going under is that if you have a round rust hole - how do you get the patch behind if you don't have access to the inside of the panel - many situations like that - rockers, dog legs, lower quarters and fenders, doors etc. Let me know if that answers you question - Jerry

I prefer to do it properly than pop rivets as I did when I was younger. Worth trying to mimic you

[@LakesideAutobody]

Thanks Curt. This is how easy it should be to weld after you set up your welder - kzbin.info/www/bejne/Z3O8on-DlNKMZ9U As for what type of welder - that depends on the $ you have. You can't ever go wrong with a 110v Miller MIG welder - the cheapest MIG they have will work great. If you don't have the $ for that, I suggest this one - kzbin.info/www/bejne/Z3O8on-DlNKMZ9U It's all I use right now and it welds great - much like the Miller. Getting repair parts will be impossible but I don't see it breaking down - it's built pretty well :)

[@feralfreebirds]

Great video, im wondering after seeing another video this morning on plug welding, if i can use this method to replace all my sills on van? he used plug welds every 2 inchs & caulk sealer. stuff( i dont know wht its name is?) ...wondering if it would be ideal , so i dont have to weld all the way along, as im beginner....but def gunna do the work myself!!

[@LakesideAutobody]

I think you'd be fine plug welding and using auto body seam sealer - it won't look perfect but it will work for a daily driver - www.amazon.com/ACDelco-10-2013-Joint-Filler-Compound/dp/B007Q0ZQGK/ref=sr_1_1?dchild=1&keywords=ACDelco+10-2013+Body+Joint+and+Seam+Filler+Compound+-+10.1+oz&qid=1594661368&s=automotive&sr=1-1 Let me know how it goes or what you decided to do - Jerry

[@feralfreebirds]

@@LakesideAutobody cheers Jerry....i will do

[@CA-pv5ie]

Love your videos - very helpful! In some of your older videos for something like this you lap weld and then knock it down to then fill. Here you switched styles - do you like this style more now?

[@LakesideAutobody]

I still like and will always prefer lap welding. It's faster, it works just as well and any other method, you can do very large odd shaped rust damage. There's no rust hole that can't be fixed using lap joints. Remember, every car is lap welded together. The floor even has lapped seams (with no weld through primer) and it lasts for a very long time before the rust gets it.

[@snoopu2601]

Yeah I saw a video it was a gas tank door he did that method of butt welding. I guess you can use anyway that works for you. I made my patch panel before I did any cutting to make shire I was able to make it, so I didn't just have a big whole. I used old broken appliance fridge metal was the same thickness work well

[@LakesideAutobody]

@@snoopu2601 You are absolutely right. You pick the method that works best for you and your situation. Rust will begin at the bottom of the panel where salt water and debris gather anyway not up high where you seam is.

[@natetracy6701]

Nicely done. What are your thoughts on using metal etching primer before applying filler?

[@LakesideAutobody]

I don't think it's necessary. I've never seen it or heard of it being used in high volume body shops. I do think there is a specific process to use though and that is prepare the metal with 36 grit fiber resin disc such as this: www.harborfreight.com/7-in-36-grit-resin-fiber-sanding-discs-3-pc-69641.html Grind slow to reduce heat and always aim to cut/scratch the metal instead of rubbing/shining the metal. If you are putting filler over paint check this video out - kzbin.info/www/bejne/oaCwqGljltqif9U Hope that helps - Jerry

[@NEOATHS]

I have a question, did you completely fill the valley with weld and then grind it level or did you leave a bit of a valley and level it off with filler?

[@LakesideAutobody]

Left a bit of valley then filled it. I totally disagree with grinding welds flush. It compromises the integrity of the weld, the surrounding metal and is a big waste of grinding discs or other material. Knock it down and fill it. It lasts longer too.

[@pauldailey4477]

Do you have to sandblast and paint the inside of the door? Do you normally do that first or after the welding repairs are made?

[@LakesideAutobody]

Yes, you can cut all that in (paint it) before you paint the whole car. Remember - after painting the only thing you should have left to do before shipping it is unmask it. I like to have everything done so I don't mess up the nice paint job.

Oh no you were right with your first thought!

[@pdiz]

My old classic has the paint cracking where the putty has cracked beneath it. Any way to stop stress cracks with putty, or was it just shoddy work by an unskilled person? Or does putty always eventually just crack over time?

[@LakesideAutobody]

Body filler should never crack over time. Sometimes instead of using filler, a body man will use a ton of primer surfacer or lacquer putty to help get a panel straight. Your supposed to get it straight with just filler but that is sometimes hard to do. Anyway if you cheat with thick primer or putty it can shrink and form cracks. Not sure if that is exactly what's going on with your car but..... Any way, there's really no way to stop the cracks except to remove the old filler and do it right the next time around. Ask more ?s if that didn't help.

[@rbelang8331]

I was wondering Jerry: if you do not have access to the backside of your panel, should you paint before you weld (maybe using Weld-through primer, for exemple)? Thanks!

[@LakesideAutobody]

There is really nothing that is for sure to use on the back side. You can try all the ideas out there but the best way I have found is to make absolutely sure the panel can drain and stay dry on the inside and that the pinch weld or bottom of the panel has some type of protection that stays fluid or does not harden and eventually peel and trap moisture - here's an example - kzbin.info/www/bejne/bonEi3WvbKx2baM

[@rbelang8331]

@@LakesideAutobody Alright thanks...

[@rodgarcia6563]

How do you keep the inside of the door panel from rusting from the inside out with no paint over the bare metal? I always wondered that when watching body repair videos. Thanks for the video!

[@LakesideAutobody]

You're welcome - here's the best way to prevent rust on any car. Even new panels have nothing coating the pinch welds where metal is sandwiched together. You have to have an undercoating that can penetrate and creep to coat everything that can't get coated with paint or undercoat. kzbin.info/www/bejne/bonEi3WvbKx2baM

[@Okie-Tom]

Good work Sir! What primer surfacer do you use!

[@LakesideAutobody]

Lacquer primer - I know it sounds old fashioned but it works well, drys fast, builds fast, sands easy, you can mix it thick or thin, and you can leave it in the cup and it won't harden - real cheap too :)

[@Okie-Tom]

Lakeside Autobody. Hey, if it works for you, use it! Everybody has their own system. My absolutely favorite primer surfacer is called "All-U-Need". Made by Clausen's. Basically a spray polyester primer filler. Works great for me! Take care and quarantine yourself if you can. The virus is bad stuff!

[@franksgarage8551]

I have a tool for putting a step in for lap joint. I would like to avoid having that 45° bend sticking inside door. But your bend will reduce warpage.

[@LakesideAutobody]

The step can work too - thanks for the input Frank - enjoy the week :)

[@steelyerface21]

I didnt see any seam sealer used on the welds ? did you use that prior to the body filler or not?

[@LakesideAutobody]

No - it's not a good idea to use seam sealer under filler. Although I don't have any solid proof that it's bad - just never saw it done in a body shop. Something that would work though would be fiberglass reinforced filler which is water proof and would act like a seam sealer.

[@stanherman5604]

did you drill some drain hole in the bottom of that door so water can get out? or is the door going to fill up with water every time it rains?

[@LakesideAutobody]

Yes - drilled 3 - 3/8" holes at the lowest points. If it's your car or truck, the bigger the hole the better so that water and debris can exit. You can even blow it clean every now and then and make sure the drains are open - very important for rust prevention.

[@armandogarza7446]

[@almierz4604]

What did you use on your air filer 40G paper.

[@LakesideAutobody]

80 grit on a rubber block. Sometimes if you're sure that it's perfect you can hit it with the DA as you feather edge the paint.

[@chrismitchell45]

I’m really regretting buying the Titanium Flux 125. Not that it’s bad because it’s actually a good welder. Being purely a flux welder, it doesn’t have the traditional gas nozzle. I’m having to get the perfect lighting to actually see where the wire is and many times I don’t hit the seam because the welding helmet I have is crap lol. It’s a Harbor Freight as well and it was $59. I didn’t get the cheapest dammit! Watching you effortlessly spot weld because you know where the wire is in relation to the nozzle leaves me shaking my head and cursing my utter failure at welding research! 😂 Another great video.

[@LakesideAutobody]

Maybe you can switch out the nozzle. Remove your nozzle and go to HF or a welding place and get one that surrounds the wire / contact tip. Do you have an auto darkening helmet?

[@chrismitchell45]

@@LakesideAutobody I already tried an HF MiG nozzle and no joy. It doesn’t have threads to go in place of the stock nozzle and it’s too small to go over the stock one. The helmet is auto darkening but it’s default setting is about 6. That and the wire color is pretty close to the color of the metal. I’ll probably sell it to my friend and get a combo off of Amazon that has flux core and solid capability. I’m just learning so it is what it is. Another thing I don’t like about it, there is no explanation of what the settings, (numbers and letters) equate to in inches and volts. It’s a constant reminder that one should never buy an old English Land Rover.... from eBay,..... when drunk 😂

[@LakesideAutobody]

@@chrismitchell45 Don't do anything important when drunk! If you're serious about learning to weld and want a welder for the rest of your life - save your $ and go buy a Miller 110V MIG. Like this one: www.millerwelds.com/equipment/welders/mig-gmaw/millermatic-141-mig-welder-m00486

[@ricardosmythe2548]

What welding setup do you have? I find when I try to weld panels I end up burning through the thin steel

[@LakesideAutobody]

I have a Miller Millermatic 90, 110v, 80/20 argon/co2, .023" wire

[@YoutubeGold-dc5fd]

how do you keep from blowing through the panel while using the mig. what is the welder and settings?

[@LakesideAutobody]

If you blow through there is usually two cures. 1) turn the heat setting down (mine is usually on 1 or 2) - there are 4 settings. 2) shorten the time on trigger - In other words just a very short squeeze of the trigger - enough to get a weld but not burn through. Ask again if that didn't help.

[@stanleylosh1899]

A word of caution to the newbees with an air file. They are fantastic tools for getting a flat panel but if you let your pinky wander down between the body of the file and the clamp for the paper, it will hammer your fingernail 35 times before you can move it or stop the file.

[@LakesideAutobody]

Great tip Stanley :)

[@Gareth96v1]

Why do you body filler the whole patch and not just the area where you welded? I'm about to try to replace the real quarter panels on my '97 jeep. I bought the panels and they are already painted/primed. Do you only body filler the whole piece if it's bare metal (vs what you ground off of a prefab primed panel)? Thanks

[@LakesideAutobody]

Because usually the patch is not perfect and there are small waves, dips or whatever here and there. Might as well just get it all at once and be done. It is possible to just do what you're saying but filler is so cheap that you actually save time and get it straighter doing this. Hope that helps a bit :)

[@wadesoutdoors1914]

Only question I have . When you use the clanging tool . Say it’s a 1/4 inch flange . Do you need to add a 1/2 inch back on to new piece ?

[@LakesideAutobody]

If the flange on one panel is 1/2 inch then, yes, you'll have to have an extra 1/2" on the other (to overlap).

[@elian222]

I'd love to see more on how you fashion your patch panels from sheet metal stock :-)

[@LakesideAutobody]

I'll do a video on that with some detail

[@gamatron17]

are you supposed to use a etch first on bare metal before bondo?

[@LakesideAutobody]

No, it's best to use a nice sharp fiber resin 36-40 grit disc to prepare the surface. Filler will never chip, bubble, peel, or fall out if put over a correctly prepared metal surface.

[@shockwave68]

Question. Ive been dealing with a local restoration shop, and he told me under no circumstances do they recommend doing the 45* the lips on butt welds. His logic was that it leaves a slight opening in the V channel on the backside where moisture can get trapped in, and it has the potential to create rust and ghost lines, since you generally cant get on the backside to seal it up/knock down the lip. He also said its harder to manipulate the metal due to the difference in thickness along the channel line. Whats your take on this? Is it something you've ever seen or had issues with? Im curious if its as big a deal as he made it out to be.

[@LakesideAutobody]

People will say a lot of things if they don't use that specific process in their shop. The facts are is that every method works well if done in a way that makes it work. Body shops should be proficient at all methods in case the customer wants it done in a specific way. There is no truth in the, "slight opening idea" - none at all. Here's some info that may help you make your own decision on whats the best method for you - watch all of them very closely and it will make sense to you - See these videos for information on why the highest quality Michigan/Detroit area body shops use this method: kzbin.info/www/bejne/gHqsoKGAhLulpZY *** Also see Eastwood’s explanation: kzbin.info/www/bejne/qKGrZmOhnZmKZpI *** For longevity of this type of repair see: kzbin.info/www/bejne/bonEi3WvbKx2baM

[@pwner3dan]

Never used this method myself, usually tig or oxy weld the panels together. however the difference is this takes about a third the time that it would take me to do it. mine ends up like a new panel like from factory but there is very few customers who could afford to do that to all the parts of a car in a restoration. this is a much more efficient use of labour and ultimately still will last a very long time. Ghost lines will occur more due to lack of time waiting for the shrinkage of fillers and primers to occur before paint not so much the valley being here. i have actually never seen this method although i can 100% see benefits this would have over conventional butt welding with a mig, and flaws.

[@guillermonieri4203]

Thank you.

[@LakesideAutobody]

You're welcome

[@ogvega71]

After tac weld, do you weld all the way through even ?

[@LakesideAutobody]

You can - One guy I worked for made us weld solid all the way but we always cheated and never had return work. I think it does well both ways because when you tap the seam down, the filler acts as a buffer between the seam and the finish. That's how they did sail panels in the factory - the roof was connected in a valley to the quarter and lead or filler was used just like this process. Have a good weekend Oscar :)

[@MrSteveespo]

Isn't it best to use epoxy primer such as DP-74 before putting the filler on? To prevent rust from bubbling the filler up.

[@LakesideAutobody]

It is not necessary as the paint protects everything under it. That's an internet/magazine wives tale thing. Body shops put filler over properly prepared metal. Here's a good video on the topic too - kzbin.info/www/bejne/rYfLgn-nhaZ6jLc

Thanks for the video. I've seen others epoxy coat the bare steel before filling, is there an advantage to how you are doing it?

[@LakesideAutobody]

No body shop that I have worked at ever used anything prior to spreading the filler. Sanded/Ground (w/ 36-40 grit fiber resin disc), clean bare metal is a great surface for filler to stick to. The idea behind using it is corrosion protection. I don't think it would hurt if you wanted an extra layer of protection and I can see how it might help if moisture got through the welded seam. but it's not necessary especially if it's just a dent or your seam was welded solid. Hope that helps a bit :)

[@websurfer1585]

Is it not best to primer bare metal before applying body filler?

[@LakesideAutobody]

No one primes bare metal in a body shop before applying filler. If there is a company trying to sell that, I would not take the bait. In 40 years, I've never had filler come off, crack, fall out, bubble, etc. If your surface is prepared right (sharp grinding disc, sand blasted welds, very clean, no rust holes or rust it will be stuck on there forever. Just telling you what I know so you don't waste $.

What do make your patch panels out of?

[@LakesideAutobody]

A1008 cold rolled sheet metal - 20 gauge - 4X8 from Alro Steel You can use anything from 20-22 gauge or .030 to .035. Thicker for the real old stuff 40s and 50s

[@malcolmyoung7866]

I like it…👍🏻

[@philliparthur8672]

I have a question, where do you get the metal from? Do you get it new or used? Hopefully you get this message

[@LakesideAutobody]

Alro Steel in Grayling Michigan but you can get it from any metal supply place. - A1008 Cold Rolled Steel Sheet

@@LakesideAutobody Hey thanks alot for messaging me back I live in Ohio so I should be able to find some. Thank you again for the information and have a great weekend.

[@jwaynus4676]

Great video, but you skipped over the welding a bit too quick. Did you just spot as shown or continue to spot across the whole panel? Also would this work similarly with gasless mig?

[@LakesideAutobody]

I continued to spot across the whole panel. I tried flux core wire once but did not like it as much as the gas. I thought it was a little dirtier but maybe I didn't give it enough of a chance. I know it can be done though - I just like the gas.

Hello sir. What is the best automotive filler to use?

[@LakesideAutobody]

I use the most inexpensive (19/gallon). It's all the same. Others will say not but it's how you prepare the surface that really counts.

[@LakesideAutobody]

The best/simplest way this to use either of these methods - kzbin.info/www/bejne/f2m5h5-Pha6cnaM or kzbin.info/www/bejne/rYPPYoScoNd1m7s Here's the follow up video after 3 winters on salted roads - kzbin.info/www/bejne/nXq2YoeYq5x-rNk

Thanks I appreciate it

[@perillouss3506]

Just curious , how much time did this repair take?

[@LakesideAutobody]

2-3 hours. In a shop though you would lap weld and it shouldn't take any more than an hour.

[@kevinparent8843]

why arent you trying to flat it out bywelding without filler ? does it has chance to crack in time

[@LakesideAutobody]

You make it look easy, Jerry! On the top edge of say a rocker panel patch, would you recommend the 45 degree butt-weld over flanging/lap weld, if either one were possible? I'm currently butt welding the driver's side rocker patch on the van I'm working on, but might try flanging the one on the other side to compare strength and ease of filling. I suppose it depends on the vehicle, but wanted to get your opinion. The Caravan I'm doing is unibody. Thanks again, I love your channel!!

[@LakesideAutobody]

You'll get a ton of different opinions but to me it doesn't make a difference because panels start rusting from the very bottom anyway. Do what's easiest for your situation. The way you prevent rust after the repair is really what counts - see this vid.... kzbin.info/www/bejne/eqLbfnt5nt-ei6c

Question..?? Could apply for an entire quarter panel?? Thx

[@LakesideAutobody]

Do you mean weld a quarter on like this?

[@alphathefirstone1222]

@@LakesideAutobody yes..meaning can you wield an entire quater panel with this method?? can you butt weld an entire quater panel and grind those weld smooth or to do an entire quater panel does it require another method...?

[@LakesideAutobody]

@@alphathefirstone1222 Usually a quarter panel is welded on with spot welds. In the factory the pieces of metal are pinched together and welded with a spot welding machine. When you do it you drill holes in the quarter where the pinch welds were (the ones you had to drill out to remove it) and weld it on through those holes. Across the sail panel you can lap weld it, knock down the welds and fill. That's how the shops I worked in did it. We would sometimes cut the quarter panel where we needed to to save work of putting on the whole thing, You really can use any weld that works best for your situation though - butt, lap or spot, Hope that helps in a way :) Jerry

[@alphathefirstone1222]

@@LakesideAutobody i will let you know what i come up with. right now i am debating bondo or weld a new quarter .. the video you posted today ....really clear up the bondo filler method . If you get some time. check this youtuber called "D.I.Y Auto School".... I watch is his video on bondo and he always talk about how it cracks...I think now after watching the new vide u posted today...i did nt understand what the purpose of the grinder was. I thought a regular DA would produce the same surface for the bondo to take. Now I see a grinder is a must. Going buy one tomorrow....check out that youtuber D.I.Y Autobody. If you can stand the arguing they do over there. he has some okay videos...lol ..

[@LakesideAutobody]

@@alphathefirstone1222 Bondo does not crack unless someone applies it wrong. If you apply it correctly it will never crack, never bubble, never shrink, never be noticed ,etc. for as long as you live - that's the truth. There's probably filler in brand new cars that no one knows about - I'm sure they use something for small dings and imperfections in the factory.

[@mattnewby123]

as a welder by trade, I would always work from the center out to minimize warp...

[@LakesideAutobody]

Good thinking - thanks for the information Fergus M - have a good week :)

[@pettingellhammer]

That’s not really a true butt weld. The big disadvantage is you can’t hammer & dolly that weld seam to take care of any shrinkage problems that may occur.

What's the name of the tool that gives the 45° angle?

I did that with an old pliers - it has an angled head. You can use a channel lock pliers like this too: www.homedepot.com/p/TEKTON-5-in-Angle-Nose-Slip-Joint-Pliers-PGA16005/303054487?source=shoppingads&locale=en-US&mtc=Shopping
