How To Weld Thin Metal Sheet

Depending upon the weld type and the size of the sheet you can use either the regular mig welding technique or combine it with the pulsing method to avoid a blow through.

How to weld thin metal sheet.

Tig welding sheet metal. These days i ll normally leave less than half a second. But there are several ways that one can do it. Experience plays a lot in this case but you also need to know the fundamentals that come with this type of welding.

Namely heat is the biggest factor when welding thinner material. Are you planning to do weld auto body sheet metal or any thin metal welding with mig welder or tig welder you should keep in mind some critical things to avoid creating any unwanted situations and we have decided to incorporate them in right here. Welding in a sequence that limits the amount of heat can help minimize distortion in thin material. Metal inert gas is then used to protect the weld from contaminants.

Don t attempt to weld thin materials like sheet metal with flux cored wires which put more heat into the base metal. Mig welding is one of the simplest to use for welding. Forget the larger 1 8 inch tungsten electrode and use a smaller one. Mig welding for thin metal.

There isn t a definitive answer to how one needs to approach welding sheet metal. While wire feed welding sheet metal go for short bursts of welding instead of a going on a long bead. To weld sheet metal with solid wires use electrode positive ep or reverse polarity. For sheet metal i use ine welding wire and it is just as good as their flux cored wire if you want you can grab one here.

Mig is one of the best ways to weld 20 gauge sheet metal. On larger thin gauge material spread out several smaller welds over the joint. Gas metal arc or metal inert gas welding is the most commonly used welding procedure for metal sheets. Try going for a wire of 023 inches when welding sheet metal.

For instance when producing a 3 ft. And then stop to allow the weld to cool down before restarting again. Technique for thin metal the way around this is to weld in short pulses allowing a second or less between pulses for the steel to cool down. Metal inert gas for thin sheets.

In the video i ve left about a second between pulses. Weld in the vertical down position weld 6 in.
