Welding holes in thin metal or sheet metal is a crucial skill. Whether you're correcting a mistake or shaving a body so it's perfectly smooth. I have welded up a lot of holes in a truck bed using a copper backer. Some of the holes went through a couple of layers of sheet metal so when I welded up the holes, my filler metal didn't hit the copper backer and leave a flat backside. Is there any issue with getting in behind the holes and welding up any residual gap to get a flush clean finish?
the importance of metal fabrication
The smaller the hole, the less effective small stitches are. In the case of filling body trim holes where you are not using filler metal, backing up the hole with a copper bar helps to absorb the heat from the weld so it doesn’t . Have you ever welded something so thin and worn out that all you do is blow holes in it? Did you want to learn how to work around that and deliver a solid re. 3/32" 6011 is one of the most useful welding rods you can have in the garage/shop. Set machine for 45-50 amps and you should be able to fix up holes in sheet metal. If you don't have any metal to patch, you can always do field filler, break the . With the welder's gloved hand you hold it underneath the hole while welding it (or prop it there somehow). The weld does not stick to the carbon, does not 'fall' through and there is no contamination. It works fine for holes up to 1/4" and probably more. For a hole which is a slot simply move the block along as you work.

Put it behind the hole and start welding around the periphery of the hole. Weld in a circle and move to the center as you finish up. The back side of the weld will be flat. If the hole you want to weld up is any bigger a good approach is to make a plug of sheet metal the size of the hole. Then just weld the plug into the hole, using tack welds. For thinner gauge sheet metal like 18 or 20 gauge we suggest .023 (6mm) wire in your MIG welder. Keep the Stick Out Short-Stickout of your MIG wire is important when welding any type of metal, but especially sheet metal. Holding the tip too far from the surface will cause the wire to have to come out too far to touch the metal.
3. Adjust Your Torch Angle. Changing the torch angle when MIG welding goes a long way to preventing burn-throughs. Make sure you adjust the angle to shorten the distance between the tip and the metal, no matter the welding position you work in.This will make the arc more stable, giving you more control over the weld and lessening the chance of burn-through. Comprehensive 29-Piece Kit: The kit includes a total of 29 sheet metal patches in multiple conventional hole sizes, ensuring you have the right size for your specific hole-filling needs. Strong and Durable Construction: Made from 14-gauge steel (approximately 0.0747" or 5/64" thickness), these welding discs offer robustness and durability to . Add small dabs of new material around the perimeter of the hole until it closes over. Plug welding kits include pre-cut blanks in multiple sizes plus a step-style bit for drilling sheet metal. Sheet metal patch – If you lose control of the blow-through altogether, you may need to remove the damaged area entirely and start over. Grind out the .

Usually the best thing to do is to weld them up if there is any chance of moisture getting in from the back side. There may be other options that won't cause a problems later on if the holes are in the weld bead and don't go all the way through. . (on the inside) with the spray on rust converter.

Great tip for welding up holes in sheet metal, use a flattened copper pipe to aid in welding up holes.#outlawedge #mnoutlawedge#weldingtricks #weldingtips #w. Leave about a six inch "handle". Put someone on the outside with the backer. Climb in the truck and weld the holes up with a quick little circle. Nothing to grind. Actually, do it that way even if it's a restore job. . Read that from another sight while googling "welding sheet metal screw holes". Appreciate all the input! Reply . 04-07-2014 . For any sheet metal welding, I prefer a tight fitting, zero gap joint (or as close as humanly possible). For holes, if you get up into anything larger than a #10 hole, you are getting to a point that the size of the weld "blob" is going to .
These 12-gauge welding discs are designed to fill the holes in the heavier gauge metal areas of a car, including the frame and any weight-bearing floor ; This 29-piece kit includes sheet metal patches in several conventional hole sizes ; 12-gauge steel (approximately 0.1046" or 7/64") Tabs around disc allow for strong butt-weld
I have heard of guys putting brass behind sheetmetal for welding up small holes as the weld will not stick to the brass. I dont have any brass but have a ton of aluminum. Can i use that to back up the sheetmetal when welding? Im just doing about a dozen small holes and using a 110 mig. 19 ga steel.

In this video I show how to fill holes in sheet metal using a mig welder. This is always challenging do to the thin sheet metal cars are built out of today. . Yes when you heat metal it expands. BUT during welding you are heating up a small area of metal, also keep in mind that heated metal is also softer as well. The heated metal expands outward but the cooler much stiffer surrounding metal keeps it from expanding. The heated metal needs to go somewhere so it bunches up. It can be done,but I have to build up both sides a bit so that the metal is now a little thicker with material. I found that it is crucial to having the sheet metal flush with each other(lap welds) or touching completley when butt welding. . Sheet metal + Welding = Blown Holes = More practice, setting adjustments, Practice
When starting to learn auto body sheet metal welding with a MIG welder, you should opt for a shielding gas that has a higher proportion of argon gas. It is better to use instead of a high percentage of CO2. . As the metal sheets used in auto body parts such as cars are quite thin, chances are you may end up making a hole or two into the sheet . This may be due to burning through the thin sheet metal, welding molding holes, fabrication, or other reasons needed. Regardless of the reason, you will have holes that need welded shut. For years, I’ve triggered the MIG welder to weld the hole shut. However, I have discovered a much easier method for doing this. If a hole is much bigger then the o on our keyboards, take some tin snips and cut out some round circles, about an eighth of an inch bigger in diameter then the actual hole, then concentrate your weld on the new metal and blend it into the old, it should keep you from blowing holes, but the big benefit, is you don't have a bigger glob of weld .
