Stainless steel tig welding rod chart.

The following tig mig classifications for wire and rod can be used on sheet metal high pressure pipe and tubing. Tig welding stainless steel is performed by using a non disposable tungsten electrode with a tig welder for striking up the arc. But in my experience. Tig welding is most often used for welding thin sections of stainless steel and other non ferrous metals like aluminum magnesium and copper alloys.

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. 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. 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.

For aluminum the same rule applies to sheet metal roughly. However skilled welders can use this method for other materials like brass with much precision practice and skill. 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.

It is ideal for stainless steel tig welding vertical welding single carbon brazing and numerous other procedures. 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 is basically a common and unique process for joining stainless steel. How to tig weld stainless steel. Stainless is less thermally conductive than mild steel so heat does not flow away from the weld quite so quickly.
