Tig Welding Stainless Steel Filler Rod Chart

Tig welding is most often used for welding thin sections of stainless steel and other non ferrous metals like aluminum magnesium and copper alloys.

Tig welding stainless steel filler rod chart.

These factors include but are not limited to the type of steel type of weld loading on the welded joint applicable codes level of preheat level of restraint position of welding condition of the steel and service conditions. 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 following tig mig classifications for wire and rod can be used on sheet metal high pressure pipe and tubing. Since then he has used the gas tungsten arc welding gtaw aka tig process to produce an impressive collection of eagles dragons dinosaurs and more.

Coating welding positions current and tensile strength for each arc welding rod. Er308l stainless tig rod when you know that you are welding 300 series stainless steel 304 is the most common 300 series stainless used you cant go wrong with er308l rods. For aluminum the same rule applies to sheet metal roughly. 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.

6 common arc welding electrodes used for welding mild steel. However skilled welders can use this method for other materials like brass with much precision practice and skill. Welding stainless steel can be tricky because it is very good at retaining heat and this can lead to problems such as warping embrittlement and rust. The amps required to weld stainless are about 10 lower than the amps used for mild steel.

At low amperage a large rod chills the puddle a lot and can cause a very irregular bead. The next chart below is similar to the one above but it gives you more detail on the six top arc welding rods. Filler metal is selected for a specific application. There are a lot of other stainless steel filler rods like 316l 321 and others and if you know what you are welding its best to use a match.
