Hi Adrian, thanks for the tips. I’m welding new patch panels I’m making to rusty 100 year old metal. I started with my tig and the tacs were beautiful, then I ran out of gas. Switched to my mig flux core and used your tips from last time and it came out really nice, just more grinding req’d. I appreciate what you do. Thanks.

[@ACDesignsGarage]

[@lewandlo]

If you have a piece of copper plate or even a piece of copper round pipe clamped against the back of the gap to take your heat away will work. With that gap, you have to get a heat sink behind it to cool down the weld. Also if you want less warpage you have to tack every inch first then then alternate again with your tacks until you fill up the gaps between tacks. Cheers

[@JohnnyBravo02]

Can do that if you’re sectioning in a quarter panel and have no access behind the panel

[@edyy6619]

​@@JohnnyBravo02 thats the only part i hate doing quarters like 30 minutes to weld 6inch bead unless you do metal backing helpsm

[@JohnnyBravo02]

[@edyy6619]

@@JohnnyBravo02 yeah they want procedures to be done correct but sometimes you cut your panel to big end up with a wide gap to weld. Id rather have a backing have my welds hold than risk ripping off the whole section in an accident.

I figured the last part out since it seems logical, but having a backing is a great suggestion. (when possible)

[@michaelballance8055]

Thank you so much. I have watched a ton of videos on welding. I struggled years ago with my youngest son on shaving a VW GTI doors. Three sets of door panels finally got it.

[@glassgubbenfg]

Hi, I have a little tip, I have been welding in thin sheet metal for many years and I can see that you are pointing the welding wire and the heat towards the hot points, try pointing the welding wire and the heat away from the points instead. if you do that, you point the heat at colder metal and you don't burn through as easily

[@ACDesignsGarage]

Thanks for the tip ill try that.

[@iwalkalone1]

Excellent video!! I learned a couple things that I had never even considered before.

[@ACDesignsGarage]

@@ACDesignsGarage It helped today. I'm working on a 'low poly garden sculpture' and focused on edge alignment over jump gaps. Also tweaked welder, got great small tacks like you showed here. Thanks again.

[@dennis6325]

If you are running 75% Argon / 25% Co2, why did you read off the chart on your welder for 100% Co2? Just a mistake I assume. I used 20 CFH regardless, but then I did a little experiment and discovered I can really turn it down for thin sheet metal. Now I go thru the gas half as fast and the welds are the same quality. I weld thin gage steel exactly like you have shown. No gap and as high a heat as I can get that bacon to sizzle without blowouts. Good Job!

[@brianhamalainen8817]

MIG welders do add more amps with the wire feed speed; so turning up the 'speed' also turns up the power/heat. That's why your chart for C25 suggested '1/12' for 22g. Have you not noticed that the arc/puddle/HAZ is much larger/brighter on 'higher feed'?

[@SwedesGarage]

Might be true on newer MIGs, but my old one from the 80's don't change the amps with wire speed.

[@janeblogs324]

All MIGs do it. From buzz boxes to inverters

[@truracer20]

It only really comes into play on continuous welds. With this type of tack welding the extra wire feed tends to cool the puddle. A lot of welders think their beads flatten out towards the end of a long bead on thick metal because of heat soak allowing the puddle to flow when in fact the amperage is rising to accommodate the wire feed rate which the hotter metal allows for. With short circuit wire feed welding high wire feed rates cause a more continuous short circuit raising the amperage, a dead short (most amperage) is sticking the wire, the slightest short (least amperage) is when you burn back to the tip. One dial is Voltage the other dial is wire speed, so amperage is a factor of the 2. I'm sure some expensive new welders can adjust this effect but if you only have Voltage and wire feed settings on your welder then wire feed rate absolutely affects amperage.

[@cliffordd6444]

100% agree on the practice on scrap and CLEAN metal (not ground too thin)

[@leighbratcher1998]

Best video for welding thin sheet metal I have seen, and I have watched a bunch. I am working on a 1970 Datsun and the metal is 22 gauge and I have been having a hard time trying to weld. It looks like I have my heat and wire speed too low, will try again tomorrow.

[@jimdrechsel3611]

I welded heavier materials for years and had to learn the hard way for sheet metal. KZbin has helped immensely. I like the way you showed how charts on a welder are not the end all but a start. They do help for thicker materials. If you really want to know your penetration and strength do a couple destructive tests like bending back and forth. You can also cut the seam afterwards and see if the weld is solid or has pockets. I think the 2 & 70 setting would cause more heat and distortion. Also degreasing the metal makes a huge difference before welding. Thanks for a great video.

[@ACDesignsGarage]

Thank you for the comments and the support!!!!

[@keepersoftheearth6637]

Thank you for this, I've been working with thin metal trying my hand at some art, this was very helpful

[@ACDesignsGarage]

Awesome hope it helped, below is a link to video I did a while back on making a rose from sheetmetal if you want to check it out. kzbin.info/www/bejne/pmq1fKOClpaEgck

[@BlueMacGyver]

On 22 gauge you'll get that gap automatically even when its butted up because the heat of the weld is pulling the metal back during the process, but is then covered up immediately by the molten metal.

[@ACDesignsGarage]

I agree ,thats why I suggest making it fit as tight as possible because metal shrinks when you weld it, thanks for the comment 👍

[@AMMA-we3zz]

What I learned from trial and error is to avoid having a gap or just a hair line gap at the most to avoid blowing holes. Both panels will join as the heat will melt them together and where possible, place a large heat sink behind it like Copper or Aluminum. That’s how I managed to weld thin metals. It is a joke some of the replacement aftermarket panels are actually made out of 22 gage steel. I actually had to fabricate my pieces from and 18 gage and sometimes 16 gage steel because 22 gage cannot take the heat and if it did, it gets even thinner when you grind the welds.

[@ACDesignsGarage]

I totally agree, i have blocks of aluminum I like to clamp on, especially when I'm tig welding super thin stuff. A tight fit is key!!!!!

[@flatrat48]

Thanks for the tip. Wire speed! Mow I know to put more wire on that thin stuff. Awesome!

[@ACDesignsGarage]

Awesome thanks, good luck on your welding adventures!!!!

[@copisetic1104]

I use a jeweler’s torch with oxyacetylene on 22 for expansion chambers. Hold the flame tangent to the curve of the two cones then bring the the inner flame in to fuse the joint, with practice you can walk around a curved or flat pretty fast. Adjust the torch to a fine flame cone. I don’t use any rod just fuse the joints together. I’ve never had a broken pipe. Every one uses tig or mig, but I think oxyacetylene with a fine 000 or better works well a lot faster than either tig or mig.

[@ACDesignsGarage]

Awesome, id love to try that!!!!

[@enigmasvids9615]

I still use an oxy/acetylene set with a Dylan/Cobra/Henrobe hand torch. It uses fine, small precision torch tips and is fantastic in thin sheet metal with practice. It's also a great tool for brazing and silver soldering. Oxy/Acetylene torches are something of a lost art these days with all the electronically controlled welders available today. I still have a 30 year old fully manually adjusted MIG welder that I use for welding heavier/thicker steel pieces together. Great presentation.

Thanks for the great video. I have to do a lot of welding on my cars and it is a PIA with the thin metal. I am always playing with the settings trying to get a good weld. BTW, I am sure you know this, but some of your audience may not know that the numbers on the Voltage for the Millermatic are not actual output Volts. The Machine goes from 10 to 23 volts give or take, so the number 1 is probably around 10 volts and 2 is like 12v -14v or something like that. Thanks again for your video, it is really helpful.

Quick question. Sorry if it’s dumb, but when tack welding do you start on one side and drag the melted metal to the other side or do you just weld right in the center of both sheets of metal. I was told not to tack weld right in center because it could burn through but these tack welds look perfectly centered. Thanks

[@ACDesignsGarage]

There are no dumb questions, thats how you get better. You can tac it in the center like I did on this video if your fit up is prety tight. If you have a decent size gap you'll have to start on one side and wash over. Its no biggie if you blow through, just keep tacin till you fill the hole. Thanks for the question!!!!!!

What worked for me is instead of starting from the top I begin about an inch and a half away from the bottom tack. Run my weld to the bottom then begin above that about inch and a half away from where I started my last weld so the weld heat can dissipate away from the area where my next weld will end. I really hope I explained that correctly. Hope it helps someone out and great video brother.

When I'm welding using a series of spot welds, I have to jump right back for the next spot before the metal cools. If I wait for the "orange glow" to die, then when I start the next spot, the welder starts with a "studded". I see you always wait for the ""glow" to disappear before you make your next "spot/tack". What is going on with my welding??

[@ACDesignsGarage]

Maybe try turning up the heat a little at a time and see if that helps!!!

[@DangrsDave]

I use 0.030 and gap. I'm able to use a lower heat and speed setting than I used with 0.023. The thicker wire carries more current allowing lower settings.

Can you weld continually on thin gauge or like you do in the video small spot welds?

[@ACDesignsGarage]

You need to do the small spots to keep the temperature down so it doesnt warp as much.

[@BUILTFORDTOUGH79]

Thanks for the video. My issue doing cab corners is, I can’t get the Dolley behind to hammer it flat, so it’s SLOW going to try and keep from warping. I like to use compressed air, or in a pinch you can use air duster. I’m not a professional by any means (hence, why I’m watching different videos for techniques).

[@ACDesignsGarage]

I know exactly what your talking about. Those cab corners can be tough. Keep your gaps tight as possible and keep it cool like your doing. That air duster is a great idea!!! The one thing i try to do is cut my cab corners higher so I can hammer my welds and get to them easier.

[@BUILTFORDTOUGH79]

@@ACDesignsGarage thanks for the advice man, I appreciate it. I’ll try cutting them higher, as the patch panel is oversized and will allow that.

My Chevelle got hit by a drunk driver on Christmas Eve last year. Not super bad, but needs some welding on the rear 1/4 panel skin. I have been dealing with burn through with the exact same machine.

Watching again, I can have access to some 20g sheets, If i get great at those, I'll be great at 18g.

[@ACDesignsGarage]

Your right, the 18 will be a walk in the park!!!!

[@melgross]

You see that 20 ga is as low as you can go with co2. That’s understandable. It’s a reactive gas and really even 20 ga is a bit thin for that. Yeah, co2 is cheap, but causes embrittlement and weaker welds. The thinner the material, the worse it is. You, like most of us, use 75/25 so 22 ga is fine. Also using .023 or .024 wire (with the right diameter liner, roller and tips!) helps a lot with really thin work.

[@ACDesignsGarage]

Thanks for the tips!!!

I do Mig and fluxcore, but mainly Mig.

[@rodb8274]

I’ve given up trying to butt weld 22 ga zinc coated auto body panels. Sure, if you skip around the panel leaving a 1” gap, letting those tacks cool naturally, then doing another round leaving a 1/2” gap, you will have ALMOST no warpage. Great! Now the warpage and shrinkage begins. WELDING CAUSES SHRINKAGE! Connecting ALL the spots has a cumulative effect. I don’t care how cool you keep the panel, the end result is serious warping. You cannot hammer and dolly this crappy metal straight. You also cannot grind the front surface flat without pinholes everywhere. Any paint job will fail! I’m convinced that using Panel Bonding Adhesive using a contour matching backing strip is the way to go. No warpage, super strong bond and waterproof seam!

Im no good at flux core, I make a big ole mess with it, it maybe possible but no with me lol ,try it out and let me know how you do!!!

[@emilranes298]

Do you hammer and dolly while the plate is still hot?

[@ACDesignsGarage]

You could ,but No I usually cool it down with air to keep the warp down then hammer it cold, its pretty soft cold.

[@wearegame777]

So if you have a burn-through ...what is the best way to fill that hole back in?

[@ACDesignsGarage]

Thanks for the question, I usually grind the area smooth if its built up, then do a quick tac on one side of the hole then go to the other side, then do the middle to connect them, letting the weld cool in between! Hope this helps!!!

[@wearegame777]

@@ACDesignsGarage yes, thank you

[@TheGoldinge]

What you did on the speed, like 1/50 or the 2/70 can you do that on a lincoln welder?

[@ACDesignsGarage]

You should be able to, the easy way is to go to your chart on your welder and set it up to the recommendation then tune it in up or down with some practice pieces. Hope this helps!!

[@mattluszczak8095]

Whats the deal welding sheet metal can you weld with two sheets butted against each other? Will weld still penetrate?

[@ACDesignsGarage]

Yes if you have your heat set correctly its no problem to penetrate .If you have any gap it can also blow a hole lol.

[@justinmichealduncan1055]

If i had to do a weld test if i had to weld that thin type of metal onto a flate plate is it ok to mig using that stitch type style of welding?

[@ACDesignsGarage]

If it were a welding test id say maybe not, really depends on what there looking for. And also it really depends on the thickness of the thinnest material. If it were 16 ga. Id say just straight weld it but thinner than that its gonna be tough not stich welding it..But as for sheet metal on body pannel and floor pans id say go for it.

[@ironbirdclub9673]

Thank you so much

[@ACDesignsGarage]

Thanks for watching

[@kevinprivet5942]

what speed do you have the wire coming out at?

[@ACDesignsGarage]

Im gonna say it was 70 on my miller but im not sure that its acurate for inches per minute, I think its just a irrelevant number on the old machines. I have a new machine and ill be doing another video in the future and you have the accurate numbers.

[@bushpilot73]

the quarter panel patch panel I need to do...I can't get behind it to dolly it after I weld it. How do I fix the warping that you beat out in this situation? Excellent video, thank you for sharing!

[@ACDesignsGarage]

Thank you!!! Those are kinda tricky, there is 2 ways that I do them. First is to weld very slowly and cool after every tac and take your time fitting your patch as perfect as you can. The other method is if you can cut the brace out thats in your way till you get your patch welded in and hammered out ,then weld the brace back in. Just becareful that it's not structural , ive done this on front fenders alot, hope this helps!!!!

[@bushpilot73]

[@andrewbrown1463]

Great video. I’m doing the same thing but using FCAW. Lincoln 140 machine. I am on the lowest voltage and very slow feed speed. To prevent blow thru this is best approach right? I’m welding in a rocker panel patch with 22ga.

[@ACDesignsGarage]

I haven't messed much with FCAW. I just bought some fluxcore wire to try to do a video on sheet metal to see if I could help you guys out that wasnt runnin gas. Id say get some scrap and mess around with settings. Try your low setting and add more wire ,sometimes when you introduce more wire it cools the weld. Try to increase in small increments till you get the best results. Super short tacs as fast as you can may help. Make sure to subscribe and ill see if I can get a video out soon. Let me know how it goes!!!!

[@stuartbird5217]

Great video, and great accent 👍

[@ACDesignsGarage]

Thank you very much, and thanks for watching!!!!!!

[@flyermike2029]

Thanks, this helps a lot. How did you ground when you were stitching? Did you just put the clamp on the table and that was good enough? Forgive me, I’m new doing this so I’m trying to learn.

[@ACDesignsGarage]

No problem, yeah its grounded to the table, if the part was bigger id just clamp to the part. Thanks for the kind words, if you have any questions just let me know!!!!!

[@kenken-sr2vq]

what gauge steel do you use for new cars ? can you use galvanized sheet metal if its only available?

[@ACDesignsGarage]

New cars probably 20 gauge ,I like my patch to be a the same as factory or a hair thicker than the metal on the car. Most new cars are probably 22ga.

[@ACDesignsGarage]

As for galvanized id try to stay away from that stuff. The fumes welding it can cause you to get pretty sick.

[@wanmuhddanial]

Can i know 22 is what type measurement? .in my place we mostly use 0.8 or 1 or 1.2 mm

[@ACDesignsGarage]

.759mm is 22ga, here is a link I use some times thanks for watching! www.metalsupermarkets.com/sheet-metal-gauge-chart/

I have a millermatic 140 i was welding a 22g made holes my set for 22g speed auto & gas 200.what the issue? My wire 030

[@ACDesignsGarage]

22ga is tough, the thing that helped me the most is fit up, try to have no gap if you can, you want it tight as you can possibly get it and keep it cooled. Get some scrap and play with your settings. Thats how I do it.

[@dirtyjobs3995]

Great tutorial, what is the abrasion material on the air sander you used to prep / clean the metal?

[@ACDesignsGarage]

Thank you very much ,Its 80 grit sand paper

[@gene2200]

Dont sell those small Miller's anymore, had mine stole. Got a Lincoln 140 I've gotta dial in this week, not an inverter, old heavy copper type so shouldn't be to different i hope. Always used .030 any smaller and i blew holes. Think i usually set it at 2 and 60, was the 110v 70amp.

[@ACDesignsGarage]

Yeah thats what id start with, good luck!!!!

Can you use flux core to weld body panels?

You can it can be a lil bit of a pain, but doable!!

Hi, I'm not very good at mig welding. Just starting out. My wife just bought me one today and it's a gasless mig welder. I'm currently working with 1mm thick square 40 X 40mm tubing but been practicing on some scrap metal I picked up from my metal steel supplier. I seem to burn holes if I try to mig scrap. What am I doing wrong? Should I be turning voltage down?

[@ACDesignsGarage]

If you want email me some pics and ill try to see what maybe the problem. The flux core welding can be tough, im thinking about doing a how to video on it and give it a shot. Here is my email [e-mail]

[@GodofAbraham]

1 mm is difficult with flux core things you can try that should help use more angle on your gun welding at a 45-degree angle increases penetration and heat use that and work backwards and leave more wire stick out about an inch it will preheat the wire that's how I do it I hope this helps good luck.

[@JohnnyBravo02]

You ever sectioned in a quarter panel on a car? The thing about that is , it’s very important because someone’s life is at risk if you don’t do it correctly and safely and it’s not just two straight pieces of thin ass medal , it’s for sharp lines and curves. I’ve fared well but some people are terrified of it even after years of being a body tech

[@ACDesignsGarage]

Yeah I've been restoring cars for 20 years, Ive built car from vin numbers they were so ruff lol check out the link below . This is a 1968 camaro build I just finished, we started with a skeleton of a car and made a show car out of it, paint and all. kzbin.info/aero/PLly0wFZ3b0EUQDyeBwWFceGjuQEhpZl52

So what I learned here is to go for as small of a gap as possible when repairing sheet metal.

That seems to work for me, thanks for watching!!!!!

[@MidnightOilsRestoration]

I do a lot of restoration work also and it requires a lot of patience for certain. I've never done very much tig welding to be honest although I would like to become proficient in it; years ago most of the type of welding we are doing (restoration work)was done with oxy-acetylene followed by hammer welding to prevent cracking. What's your opinion on what is best for this type of work all around?

[@ACDesignsGarage]

Thanks for watching, I like the tig process over mig on sheetmetal repair because you can hammer weld it. Mig will crack for sure if you over hammer it because its so hard. I think the the tig process is very simular to oxy fuel welding. If you can oxy fuel youll have no trouble tigging it.

[@MidnightOilsRestoration]

@@ACDesignsGarage that's really interesting, I bet it leaves some really nice looking seams! I will have to invest in a tig unit.
