The following tig mig classifications for wire and rod can be used on sheet metal high pressure pipe and tubing.

2 2mm is the transition between 1 0mm and 1 6mm filler rod.
Additionally 309 309l is recommended for welding 304 to carbon steel or for the barrier layer for overlays on carbon steel.
Tig welding is most often used for welding thin sections of stainless steel and other non ferrous metals like aluminum magnesium and copper alloys.
Er308 and er308l one of the most common welding rods it s the choice for welding 304 stainless steel which is widely used in manufacturing as well as 200 series and other 300 series steels.
3 3 austenitic stainless steel the austenitic stainless steels contain 16 26 cr 8 24 ni mn up to 0 40 c and small amounts of a few other elements such as mo ti nb cb and ta.
This process also uses shielding gas against contamination but you can weld thinner metals more efficiently.
Stainless is less thermally conductive than mild steel so heat does not flow away from the weld quite so quickly.
This is basically a common and unique process for joining stainless steel.
For stainless sheet metal one size lower than you would use for carbon steel seems to help because typically less amperage is used on stainless steel than on carbon steel.
Post weld heat treatment to soften and toughen the weld.
The 316 316l types of stainless steels contain molybdenum mo and are commonly used in more corrosive applications than the 304 type.
The larger filler rod cools the weld pool more than the smaller rod so you might add about 5 amps if using 1 6mm filler rod.
Alternating current power supply an ac power source alternates the current flow from positive to negative and negative to positive around 120 times per second depending upon the frequency of the supply.
Tig welding stainless steel is performed by using a non disposable tungsten electrode with a tig welder for striking up the arc.
How to tig weld stainless steel.
It is ideal for stainless steel tig welding vertical welding single carbon brazing and numerous other procedures.
The balance between the cr and ni mn is normally adjusted to provide a microstructure of 90 100.
At low amperage a large rod chills the puddle a lot and can cause a very irregular bead.
