How To Weld Sheet Metal With A Arc Welder

Mig welding uses an arc of electricity to create a short circuit between a continuously fed anode the wire fed welding gun and a cathode the metal being welded.

How to weld sheet metal with a arc welder.

While wire feed welding sheet metal go for short bursts of welding instead of a going on a long bead. The real trick to weld sheet metal is to use a wire feed. This adds two operations. So you can keep the other hand free for manipulating your materials and other tools.

Just kidding this tip is to explain how to weld sheet metal with a stick welder. Disclaimer due to factors beyond the. A standard arc welder is undoubtedly the best way to weld galvanized steel. Short bursts or tacks will help.

Yes arc welding sheet metal is difficult tedious and probably a bit insane but it is feasible. Mig or metal inert gas welding aka gas metal arc welding or gmaw also uses a gas shield and filler material however in this case the filler is a wire fed directly through the welder. Any arc welding process general recommendations the best way to weld galvanized steel regardless of welding process is to remove the zinc coating from the joint. Tig welding sheet metal.

Every surgeon can operate a scalpel but only a few could work with any tool. As a rule when mig welding sheet metal never use a body filler metal that is thicker than the base metal. I would compare it to performing plastic surgery with butcher knives. It is recommended that a welder should use 023 or 024 inch wire for light gauge sheet metal work.

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. We need to establish what is considered thin metal. How to weld thin gauge steel similar to car body panel down to 8mm or 1 32 of an inch thick with arc or stick welder. Try going for a wire of 023 inches when welding sheet metal.

To weld sheet metal with solid wires use electrode positive ep or reverse polarity. A wire feed or tig welder is ideal for sheet metal but we will assume that you don t have one. Removing the coating and re spraying or painting the weld seam after welding to regain corrosion resistance. Forget the larger 1 8 inch tungsten electrode and use a smaller one.

The heat produced by the short circuit along with a non reactive hence inert gas locally melts the metal and allows them to mix together. That makes this a one handed process. Don t attempt to weld thin materials like sheet metal with flux cored wires which put more heat into the base metal. Now you know the secret of arc welding thin metal sheets.

There is occasionally splatter from the spread of the arc.
