(Text on screen): How to Weld a Steel Patch Using a Copper Backer, Kevin Caron, www.kevincaron.com The Voice: Hey, Kevin. What are you doing? Kevin Caron: Well, have you ever had a hole you had to fill in on a piece of metal? The Voice: Yeah? Kevin Caron: I’ll show you a little trick here. Here, let me just tack this together real quick and then I’ll show you something you can use. (welding) OK, so anytime you wind up with; you’ve got a little hole here, working on, like, a body panel, you’re working on a, you know, a little something. You’ve got a hole, you blow a hole in it, the fit isn’t quite good. Here’s a little trick you can use. Copper! It melts at a much higher temperature than steel does. So, as long as you have a piece that you can shape (this one’s a little thick to shape, but . . .) You have a piece that you can put behind your hole, and then clamp it on, like behind a body, or just right here on the table. Now you can come in and you can weld that steel, lay the fill right down inside that hole. Fill that hole all in. It’s not going to stick to the copper. It’s not going to blow through. You don’t have to fight and have this big glob and then you’ve got to go back and grind it all. Now, let me show you. (welding) See, I can start to fill this hole in here. You know, if you look at the back side, you can see it here. So I could come back in and grind this just a little bit. Or I could even come in with the TIG and get it just a little bit more on the back, just to fill in any little gaps that are there. But you can see how nice and smooth it came out on the back. No big bubble, no big glob to deal with or anything. And as for the copper, we just wound up with just a little burn mark on it. That’ll just buff right off, and use it again. Great, great thing to have around. You know; little different-sized sheets. You can get some of the thinner sheeting. I’ve even gone so far as to take a thin sheet of copper and a couple of rare earth magnets, and you can put one piece on the back side of the copper, the other piece on your steel side, and they’ll clamp together. When it’s so far in, you don’t have a clamp that you can reach in and do it with. Good thing to do; good thing to know. I’ll catch you next time. (Text on screen): Subscribe to See More Videos!
