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. 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. If you are new to welding and only have room. To weld sheet metal with solid wires use electrode positive ep or reverse polarity. Forget the larger 1 8 inch tungsten electrode and use a smaller one.

Removing the coating and re spraying or painting the weld seam after welding to regain corrosion resistance. That makes this a one handed process. Arc welding is a versatile method that uses alternating currents to create a high heat arc that melts your flux. There is occasionally splatter from the spread of the arc.

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. A standard arc welder is undoubtedly the best way to weld galvanized steel. If you can work outside when using an arc welder.

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. 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. Tig welding sheet metal.

Disclaimer due to factors beyond the. The real trick to weld sheet metal is to use a wire feed. Now you know the secret of arc welding thin metal sheets. Just kidding this tip is to explain how to weld sheet metal with a stick welder.
