Stainless Steel Tig Welding Amperage Chart

It s the most commonly used shielding gas for tig welding a wide range of materials.

Stainless steel tig welding amperage chart. Stainless is less thermally conductive than mild steel so heat does not flow away from the weld quite so quickly. Browse suggested weld parameter settings for tig welding. This will require traveling much slower and therefore produce more heat input on an overall scale. Tig welding stainless steel is performed by using a non disposable tungsten electrode with a tig welder for striking up the arc.

The more heat you put into stainless steel tig welding the worse your weld will look and the more your project will warp. This is basic set up information if you have questions please leave it in the comments sections. The amps required to weld stainless are about 10 lower than the amps used for mild steel. The foot pedal starts at 0 amps in the resting state and will gradually increase in amperage as the welding operator pushes the foot pedal down to a certain limit.

Shielding gas 90 of applications can be done with 100 argon. It is ideally preferred where the chicago welder fails because of its limitation in doing the stainless steel soldering job. Post weld heat treatment to soften and toughen the weld. Pure 100 argon can cover almost all your welding needs.

Carbon steel stainless steel and aluminum can all be welded using pure argon shielding gas. The unique characteristic of tig welding when it comes to amperage is that the foot pedal on the tig welding machine controls the amperage needed in the weld per the user s input. The balance between the cr and ni mn is normally adjusted to provide a microstructure of 90 100. Tig stands for tungsten inert gas which is a welding technique done with the help of tungsten electrode for heating different metals.

Beginners might find the stainless chart handy for mild steel the lower amps will compensate for a slower travel speed. This process also uses shielding gas against contamination but you can weld thinner metals more efficiently. The tig option can be deployed for doing the stainless steel welding task. 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.

However this does not mean that you should turn down your amperage. How to tig weld stainless steel. In fact as little as five amps can make the difference between the perfect weld and a blued or burnt through part. It works with steels stainless steel titanium and aluminium.
