How To Tig Weld Thin Sheet Metal

Gas metal arc welding gmaw is an effective method for joining light gauge metals such as carbon steel and austenitic stainless steel.

How to tig weld thin sheet metal.

Sheet metal is only thin. Carbon steel and 18 ga. Typically call for a size 7 tig cup. Forget the larger 1 8 inch tungsten electrode and use a smaller one.

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. In thin applications shielding gas on the backside of the weld reduces heat input. Tig welding is the way forward for metal under 0 6mm and a mig welder with decent power and wire control is needed for anything less than 0 8mm. It produces good quality results and is usually the preferred method for autobody repair unless you re a very experienced welder.

Stainless steel are used in applications such as hvac automotive mobile machinery guards and cabs and small parts as well as stainless steel food service and processing. Auto body sheet metal welding with different welders. But using this method also requires some practice and practice advice in order to understand it. When you re welding body panels you can either mig weld or tig weld.

Tig welding for sheet metal. You can use a welding rod of any size as long as it works with your welder. Using a tig welders means that one can work on materials of 26 gauge. Using this process enables more than effective work on thin materials as it provides high precision and high quality work.

Keep in mind that a bigger rod is going to weld a larger area than a smaller rod. The backing bar is used commonly by welders to cool the welded metals and they are generally made up of a copper or aluminum metal and clamped to the base of the weld piece whether it is just a piece of thin sheet metal or a body panel you can use it either way. Use a 6013 7018 6011 or 6010 welding rod. Tig welding sheet metal.

For welding sheet metal in aerospace applications use a 15 cup 15. To weld sheet metal with solid wires use electrode positive ep or reverse polarity. I was hoping to manage a butt weld too but the metal was far too thin for mig and i just blew holes. Mig welding is the easiest process to learn that has revolutionized autobody repair.
