[@rickdee67]

I did collision repair for over 30 years! This is practically the same method that I used and the only way to do it however for the sake of strength and to give the Weld a backing I will put a 2 inch piece of the new quarter panel inside lapped under the skin on each side of the joint. Especially at the rocker.

[@mhughes1160]

In the 80’s and 90’s some people were saying the metal was to thin LoL 😂 Welcome to 2024 some areas are paper thin now. 👍

[@rickdee67]

@@mhughes1160 RIGHT!? 22-28 ga! You do nice work.

[@edjackson4389]

I do the same thing. I drill a few 3/16 holes on each side of the weld and spot weld the backing plate to hold it in place and for a little extra strength. Makes welding up that seam alot easier too

[@georgemichaels2325]

I do the same thing, but add a backing plate a little thicker than the replacement panel.​@edjackson4389

[@jasonehredt968]

Most manufacturers disallow a backer these days. Open butts only.

[@johngaller278]

Lots of critics on here... To be expected. Thanks for sharing your skill and knowledge. Appreciate it.

[@artszabo1015]

Yes, absolutely yes!

[@richardberryhill718]

Love then clear instructions WITHOUT music! And the comment to lap a portion of the new panel under the old for solidity.

[@lynnclay3190]

Been doing it like this for 30 years. I allways tack in a bonding strip beneath the joint for strength and to reduce sparks on the inside. Lots of stuf in there that can and will catch fire such as noise insulation.

[@saneauto]

Precise and straight to the point. Good clear voiceover. Well lit & in focus work. Great Job.

[@raydreamer7566]

Great tutorial video. I have done this many times even for wood projects . I learned your trick from a pro painter who was installing wall paper in an commercial building by the elevator. Even though I am electrician I still learn lots from workers around me . STAY ALLERT FOR LEARNING AROUND PROFESSIONALS .

[@EnglishCad]

I used to make up a fillet to go inside between the two panels where it butts up, then weld it together. Helped stop heat distortion. Quick grind off. Perfect finish every time. I did this work ( body and paint) for 25 years. 6 days a week. 12 to 15 hours a day. I got so prolific it wasn't unusual for me to be working on 8 cars at a time. Getting them ready for my guys when they came in the next morning to get them in the booth for paint. Didn't do my marriage any good however.

[@elbassaraghii5744]

[@robertcheslock9636]

Learned this method back in the 70's when I was doing body work. Replaced several complete roofs on rollovers.

[@rex8255]

I like seeing people do body work (as opposed to bondowork)

[@jaarts359]

As an ex collision tech, I say looks great. Those cut and welds are harder to do than most would know!

[@charlesloomis2224]

Short, simple, and to the point. 👍. Looks simple enough until you have to do it. It requires a sharp blade and a steady hand when cutting. The blade can be purchased any day of the week but the steady hand…that takes time and experience to make something difficult look easy.

[@IROK660]

Love it!! Concise and to the point. Too many 20 minute videos with 18 minutes of the person holding rhe camera on themselves.

[@1hjehje]

A very professional and nice looking job. I am retired now, but this brings back memories of when I was young and worked with my father in our autobody repair shop. It is still interesting to see the new tools and techniques that are being used in the industry. Thank you for the video!

[@WilliamVG]

Can you do a video showing us your welding setup? Thanks.

[@AUTOBODYTECH]

Sure!

[@MrMuffanga]

Gap is a little big. The best way is cut the new quarter where it needs to be. Then over lay it and scribe a line with a sharpe object. Cut the panel and debur both panels. Youll then have a super tight gap. As for the techs that say to use a Backer. Im against it as it doesnt allow cavity wax to get between the backers. If its a butt weld then youll be able to spray it with cavity wax. Most of the time procedures say Butt weld only. I forget what they call a butt weld with a backer, i think its called a "fillet" remember seeing it on the symbol sheet for a quarter i just finished up.

[@MH-on8ol]

I personally like to see a sleeve added with some plug welds. It really adds strength in the rocker area.

[@HackMasterBlaster]

I’ve done many with sleeves but these days you have to follow manufacturers procedures. If they don’t allow one (most don’t) then you shouldn’t use it otherwise you’re making yourself a liability.

[@TheKebobhunter]

[@dyingforpie6879]

Dude excellent work! Im jealous

[@louf7178]

Never did it myself, but in my recollection, MIG welders changed the game; then technique improved to be able to make these idealistic joints. Leading was the excellence before that, too.

[@dougpeters1625]

That is some fine work.

[@melikestuff8389]

Keeping it simple. Good job.

[@arthurwagar88]

Nice cutting tool.

[@DoThingsYk]

Clean work🔥

[@Encryptus1]

I used a similar tecnic to cut a board of wood to fit a especific hole. Bigger board that covers the entire hole and then cut both. I cut it on a 45º angle in order for the board on the wall not to fall inside the wall. In metal, that won't help you. Maybe make three cuts and tack weld the cut corners. Then finish the cut.

[@christiantroy7722]

Good job hear in Australia we have to remove the panel at the original join seems and spot welds cut and shut jobs like this are illegal the was to many bodgers doing bad work and car's would break in two in an accident so it was outlawed you would need to reinforce the joint and get an engineer report if you want to do it this way even a chop top needs to have a engineer report before it can go back on the road it makes custom work a lot more difficult to do hear and much more expensive for the customer

[@wheels-n-tires1846]

Wow thats crazy!! I mean, I see the point but i bet it makes life and doing custom stuff really tough!!!

[@markpayne6803]

USA here educate me what's the definition of a bodger never heard that term before Thanks

[@vipcress]

​@@markpayne6803 I think it's a combination of the word dodgy and botch-job.

[@johnhall1299]

Same here in the US, not the official OE procedure, not crash tested. Some of the 1500 MPa panels become much weaker at the heat affected zone of a butt weld. Times and materials have changed. Look up 3M and John Eagle Honda.

Good evening sir, thank you for sharing your experience and expertise. What brand of welder and size wire? Your welder really sounded like it was really kicking it. Take care and good luck.

[@AUTOBODYTECH]

It's a GYS welder, and I'm using .23 solid wire

[@FLORIDAMANIAM-he2lz]

I would have used an agle grinder. Its more precise or maybe its just my ability to use one like pocket knife. But dope sauce, dude killer work!

[@daviddntait]

The metal dust from the grinding process will spoil the paint work that will be done. Basically, the body saw is easier to contain. Still makes a mess but it won't shower everything in hot slag.

[@SteveWrightNZ]

@@daviddntait Diamond disc not so messy

[@davidgentz1731]

I have used that tape trick it works really good for your blade to follow it's better than a pencil line

[@martycaldwell7197]

I almost always put a backing plate on most joints. It's ez and less filler you don't warp the metal as bad .don't care what aldata says. It's a skin when you start messing with structure hole different story .

[@mistersinister2043]

But then you're never able to completely apply corrosion protection to the joint

[@tillross4078]

Digging that cutting tool ,, Air saws all ?

[@AUTOBODYTECH]

Yup!

[@rodb8274]

I prefer to use panel bond adhesive with a series of backing strips glued to the underside of one side. The backing strips are 1 5/8” wide, leaving a 3/4” flange on each side of the gap. This is clamped using aircraft Cleco Clamps through 1/8” drilled holes. Then glue on the new panel by laying it onto the flange created by the backing strip. Then fill holes with more adhesive. This creates a super strong double thickness joint that has zero warp, no sparks and is completely watertight.

[@AUTOBODYTECH]

@@rodb8274 this is a similar method to how BMW and MINI do it. I will have a video with that coming soon.

[@letsride2057]

Did a lot o q panels year ago. Move your cut line forward four inches and have less welding and grinding... time is money

[@AUTOBODYTECH]

@letsride2057 agreed! except that this is exactly where the manufacturer wants the cut. If I could choose, it would be the smallest part of the panel

[@southerntrendkiller2632]

I feel like that sail panel and rocker should be sleeved, with plug welds on both sides of the butt joint. But, it still looks good from the outside, and you only replaced the outer skin, with no structural damage that I saw. Good job.

[@AUTOBODYTECH]

It really depends on the manufacturer specs whether to sleeve or not. When sleeving these joints, it does add strength to the welded area and may actually be counterproductive to the ability for it to collapse as designed

[@southerntrendkiller2632]

@@AUTOBODYTECH very true. I’ve been out the business for about 14 years now. And only do my own jobs, flipping cars for profit and of course building my own projects.

[@harryloibl5183]

Thanks buddy 😊

[@jasonh8416]

Nice job although it does leave a good sized gap that needs to be filled with weld. What if you tilted the saw over, like on a 45 degree angle while cutting? Then the panel that's resting on top, once cut, would lower down to make a tighter joint, wouldn't it?

[@AUTOBODYTECH]

Yup, it would. I've seen this technique before 👌 🔥

[@suecobandito8954]

Like doing wallpaper joints only harder.

[@trship6274]

Could you use a flux core MIG for the weld?

[@AUTOBODYTECH]

@trship6274 unsure of this.. I don't think so..

[@ToadleyBrowne]

I-Car. The panel needs a sleeve. Butt joint will fail when destructively tested. Nice presentation on matching 2 metal parts.

[@richardwarfordjr.5622]

Yep that's metal 101

[@chendo627]

thanks great tip

[@janetpearson1455]

how do you seal the inside from rust?

[@AUTOBODYTECH]

From a nearby cavity with a 360 wand attachment or from the backside, if you have access

[@rfreitas3298]

I did that with double sided tape on flexographic printer

[@willconklin7739]

Question, why not use the entire length of the new panel to repair the damage further up on the pillar?

[@AUTOBODYTECH]

This is where the manufacturer wants the section. Anything further, you would be replacing the side aperture and be getting into the roof panel.

[@Regal2800]

Did you tig or mig weld the joint?

[@AUTOBODYTECH]

Mig

[@rossokeefe9268]

What brand airsaw are you using and what kinda pressure are you running it on...my ingersolrand dont work that good

[@AUTOBODYTECH]

Lenox or crytool saws. And not sure on pressure, I don't have a regulator on my saw but the astro saw works really well. I'm really happy with it especially for the price too

[@user-pw7wl3nu1l]

Awesome work. I'm just wondering why you're not using grinder I think it's much easier?🤷

[@FLORIDAMANIAM-he2lz]

I said the same thing. But maybe its our perception from using them for ever.

[@leebdj1949]

I started trying different cutting tools like jigsaw, hand held band saw, die grinder with multiple cutters, even a recip saw with zero clearance foot. I used grinder a lot, but get annoyed with the abrasive dust, and sparks getting everywhere. If you have anything in the shop it gets covered with shit, especially windshields, and wipers. I welcome any techniques that can replace the grinder if possible. Nobody’s wrong, just my choice.

[@peggyseefeldt2638]

Seems more controllable with a cutoff wheel grinder.

[@Gatf4]

If I wind up with cancer when I get older I feel like it will be sure from Grinding wheel dust. All young guys should have full face shields and respirator on for even the simplest little cuts. JMHO

[@davidmilne9738]

Im going to be mounting a service bed on a truck. It will be welded onto frame and i need a product to protect from rust…any recommendations?

[@davidmilne9738]

Don't weld it! Use the recommended U bolts. Vibration from driving could cause the weld to crack. I built trucks like yours for years. Plus if the truck is wrecked you will have a hell of a time getting the box back off.

[@AUTOBODYTECH]

I agree with using u bolts, but if you were to weld it. Definitely get it painted, then I undercoat it with 3m cavity wax or fluid film.

[@kellyappel3015]

So, what's the thinnest cutoff wheel out there and where do you get them? I assume you're going with .023" wire too?

[@bogey19018]

Do you strengthen it on the inside with any metal?

[@AUTOBODYTECH]

Nope not unless the manufacturer states on the procedure

[@wheels-n-tires1846]

Just curious- if you have a complete new panel, why not drill spot welds and use whole thing and avoid the butt weld altogether?

[@samg5543]

You can't buy the whole panel new. you have to section it. if you install a full used one, you'd probably have to remove the roof skin also.

[@wheels-n-tires1846]

@@samg5543 ok fair enough- i just assumed it was a complete replacement panel... With my old cars ive had to do that so thats just what Im used to, and its nice because there isnt any seams to weld.

[@AUTOBODYTECH]

Yup! You would be getting into the roof. Also, insurance companies won't pay for a complete side apertures so we order the quarter skins only and these are generally where manufacturer allow you to join them.

[@wheels-n-tires1846]

@@AUTOBODYTECH yikes!! Well im glad I only do 60s Mopars (although I did do a quarter panel on a 92 Stealth, its on my channel) and also glad its for myself and not insurance companies!!!😁

[@mobylas]

Hi there, the repair is well done, BUT, modern high carbon steels should not be welded, but the gap should be sleeved and MIG (CuSi) brazed. A complete weld over that distance makes the panel weak. In a next crash it will crumble there (the seam) or rip off. Trie yourself, make a weld with two modern metals (high carbon steel) and do the same thing now sleeving the seam and MIG brazing it. Than trie to tear both panels, you will be surprised..... ; ) Keep on hammering...

[@AUTOBODYTECH]

I've always wanted to learn MIG brazing. I disagree that it will crumble or rip off in the next accident, all though MIG welding does cause it to become more brittle. There are other manufacturers such as BMW that glue their quarter panel section with a backing plate and this is considered safe. Thanks for sharing!
