Welding Thin Sheet Metal

Here s a shot of 0 3 mm stainless cut from a 5l thinners can that was welded in this way.

Welding thin sheet metal.

Auto body sheet metal welding with different welders. I was hoping to manage a butt weld too but the metal was far too thin for mig and i just blew holes. For 3 32 7018 s it s about the same. A good heat setting for 1 8 6011 rods on thin material is about 80 90 amps.

Everyone is different but those settings will get you in the right ballpark to weld sheet metal. As a rule when mig welding sheet metal never use a body filler metal that is thicker than the base metal. When it comes to welding thin sheet metal like car body panels if you are not experienced and skilled enough then you can easily create a mess as blow holes in the sheet and make the metal useless.

Don t attempt to weld thin materials like sheet metal with flux cored wires which put more heat into the base metal. It is recommended that a welder should use 023 or 024 inch wire for light gauge sheet metal work. Did you want to learn how to work around that and deliver a solid re.

Do not try to run a bead from one end to the other. 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. Some bodymen prefer to pause after each short weld bead then hammer the weld if you can get a dolly behind the patch to help relax the panel back to its natural shape.

Just grab a piece of sheet metal to get the heat set correctly and go to town. Avoid warping the sheet metal. In this article we are taking a look at how people should go about welding sheet meta l what kind of wire and shielding gas need to be used. 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.
