How to MIG Weld (THIN) Sheet Metal (Plus BONUS Content)

In this video I demonstrate how to set up your mig welder so you can weld thin sheet metal. We also showed in this video how to make your pattern, fit and weld it in. I demonstrated this project on one of my old c/10 front fenders. This process can be used in rust repair, customizing and panel repair. I hope this video helped you understand the process of thin metal repair and welding. Hope you enjoyed this video, Please LIKE and SUBSCRIBE if you got value out of this video.

Learned more in 40 minutes than 5 other how to videos, combined! Great job! Thanks a million! God Bless you too!

[TailSpin]

Almost 40 minutes long and I couldn't tear myself away from it. Great content. You showed enough detail to make it interesting and informative and covered all the bases without making it seem long and boring. 👍

Great video by a natural born teacher. Thank you

Great "home" welding in garage for nearly 25 years and just learned how to weld even better thanks to you....God Bless and keep em coming....

Thanks telling your viewers, that grinding welds can distortion of panel ( problem people over look. ) good man.

Thanks Martin - UK.

26:55 I always find it amazing how the camera can capture stuff you don't usually see while welding. Check the upper right corner just as he cools the panel down, you can see the metal shrink and start sinking back down.

TIP: Round patches have the least distortion. The sharper the corner, the more distortion in that area. Replacing 90 deg corners with a pair of 45's makes a difference.

One thing I learned in the machine shop, was to cut the patch/inlay bigger than the hole, hold it in place and use a scribe to mark and cut/grind “to” the line.

Thank you for this video. I have been dragging my feet for 4 years on a project simply because I am afraid to weld. Never done it and starting on 20 gauge is a bit daunting. Bought some 2x4 plugs to practice on and I was getting a funky sound and the wire was going back up into the nosel. Going over the weler settings helped and I went back out and brought my wire speed up a bit until I got a better sound and better weld. Still practicing but making progress!

Thanks for the great video. I've been procrastinating on all of the rust repair I need to do on my '74 VW Beetle. After watching your video I'm much more confident that I can do it well. I like the fact that you speak about what you're doing and how to do it in between the actual work. The details you provided really help people like me who have very little experience.

One of the clearest explanation guides on YouTube 👍🏼

Nicely done, im not a welder, but by watching your video I think I might start a new career.

I learned a trick that helps keep the patch in place. use magnets on the back side spanning both pieces of metal. this will keep the patch from moving around .

I'm no expert but his the best I've seen so far on tute vids. Couldn't tell it wasn't all the original panel. Thankyou for sharing your experience.

[teymac]

Great video! You’re an excellent teacher. Everything is explained in detail. Being a novice I can’t ask for more than that.

[staninjapan]

Good one thanks!
I no longer weld and have not done for three decades, but I do love a good restoration video.

[mitchwakeland]

Great job, great video. You walked through the project well and to the point. Well spoken too.
I get it that some people always have special ways or you could have, should have ways but your video was to the point. Not many if at all, you could do it this way or that way.
You did it your way and did it great, I'm sure you helped many people get started.

[fastjeffy]

I’ve been watching body work videos for a few months now and this is the best one I’ve seen. Thanks a bunch

Nice job! When I cut a hole for a patch, I make the patch on the area to be patched then use the thin cutoff tool to cut into the main panel at 45 degrees which also cuts the patch at 45 degrees. This method eliminate the gap between panel and patch and the patch will actually lay into the cut hole then all you have to do is clamp it with a deep throat clamp or magnets and weld it up. I like to use my Henrob torch to weld. The weld isn't as hard as a MIG weld, it's easier to clean up and there is less warpage. I also use "Bastos" as a heat sink, (waaay back in the day, I used to use wetted down asbestos fiber for that. I'm sure that I still have around 15 gallons of that sitting around somewhere). I love those paint stripper wheels. For a guide coat I use the 3M rattle can spray. For filling small holes, I modified myself several pairs of vice grips, giving them unequal length jaws. I put a copper penny on the lower jay and close the grips. This give me a very stable surface to weld against, and the best thing is, it only costs pennies.

I am just starting to learn to Mig weld, and will work on my 1956 F100 and your video showed so much detail and you worked slow and steady, meticulous which I appreciate as I only want to do my repair once :) Thank you.
