Welding question

[lowrider91]

Hello everyone. I am going to weld a small piece(2x3) on the rear quarter. I have a Millermatic 210 wire feed. I am not a welder, just a landscaper with a welding machine. My question is what kind of heat do i use on this thin metal. I don't want to warp the panel. I am cutting the patch out of bad front fender and will cut it up and practice on that before I try the patch. What size tip should i use? You guys have been a big help already. Happy to have a place to go for good info.Thanks in advance, Jim

somewhere on the miller website they have a reference guide that will help you with heat setting rcommendations, wire size etc. based on the thickness and type of metal you are welding

.025 wire,medium setting,move your tack welds around,DO NOT concentrate your welds in one area,work your way around the patch.For example,top left,bottom right,left side bottom,right side top,keep bouncing around the edges until you have connected all the tack welds.When it is solid grind it down;again DO NOT concentrate your heat,move your grinder around!! I like to use a cutting disc on edge to get the welds down then switch to sanding discs. ROY.

Weld no more than 3/8" at a time. This keeps the metal from getting too hot and warping. As Roy said tack all away around the piece, skipping from one side to the other, never twice in the same area. Keep tacking until you have all the tacks about 1/8" apart. Then start connecting the tacks but weld no more than about 3/8" and stop and go to the other side and do the same. Stop and look at your work, take a deep breath and do it all again. Take your time letting the metal cool a little bit between welds. Don't worry about the looks, It will look terrible but you are going to grind it all off. As you start to grind you may see a few pin holes. Try to weld them up before you grind the metal too thin. In some places you may have not had the metal aligned just perfect when you butt welded it together. Don't grind all the way through trying to get it perfectly smooth. That is what body filler is far. Practice on a piece of scrap that is the same thickness before you start on your patch plate. Remember, you can't learn to weld by reading, it takes practice.

ita all good advise, I'm sure someone will use it but he's probably got that patched by now

The inside corners would blow out on me some so I started saving them for last or just cut diagnally across corners on some. works for me

Thanks guys. Been a while. Had some personal and buisness set backs the past couple years. My car has neen blasted to bare metal, metal work done and painted Black. Still up on jackstands. Sold my sleds for some engine money. 347/450 being built by Proformance Unlimited in NJ. Just got some front end stuff from Opentracker and CSRP. Took apart the 8in rear for some paint, new gears and posi unit. Tearing apart the toploader for a rebuild over the next couple weeks. When I figure out how to get pics posted I will get some on.
