And this welding process is still very popular today mainly because it does not require much equipment and does not require power.
Best gas for welding sheet metal.
The high carbon dioxide content does a good job of welding through the zinc coating.
How to weld auto body sheet metal with a tig welder.
Welding of carbon steel can be done with carbon dioxide alone and it produces the deepest penetration the most smoke and the roughest weld.
Ditch a 1 8 inch tungsten electrode for something much smaller like 1 16 inch tungsten.
Tig welding sheet metal.
Because it will have you a lot more control over.
The most widely used mixture is called c25 and that is 25 carbon dioxide and 75 argon gas.

The 5 best welders for sheet metal.
The best two electrodes for welding auto body sheet metal is either ceriated tungsten or thoriated tungsten.
But keep in mind that thinner material like sheet metal should not be welded with flux cored wires.
Holding the tip too far from the surface will cause the wire to have to come out too far to touch the metal.
While wire feed welding sheet metal go for short bursts of welding instead of a going on a long bead.
If using short circuit transfer in thinner parts using 100 is acceptable but will generate more spatter.
Short bursts or tacks will help.
Always use the smallest wire diameter possible since smaller wires take less heat to melt and heat the metal less.
Tips for welding sheet metal with mig or tig.
Welding gas for stainless steel while choosing the shielding gas for mig welding stainless steel welders usually prefer a mixture consisting of argon 98 and co2 2 while some prefer to use the gas mixture of helium 90 argon 7 and co2 2.

Why would i ever want to gas weld anything.
So the question is.
For these types of materials a tri gas mixture is recommended which consists of 90 helium 8 argon and 2 co2.
For thinner gauge sheet metal like 18 or 20 gauge we suggest 023 6mm wire in your mig welder.
There are other mixtures that work well depending on the type of welding that will be done.
Try going for a wire of 023 inches when welding sheet metal.
Oxy fuel or oxy acetylene welding are gas welding procedures that were invented in the early 1900 s.
If you will use spray transfer then got with not less than 20 carbon dioxide.
