How To Tig Weld Stainless Steel Sheet

The tig option can be deployed for doing the stainless steel welding task.

How to tig weld stainless steel sheet.

Welding will always need heat otherwise the metals won t weld together but the heat on stainless steel is from the job heating up more than it needs to. Tig generates heat via an arc of electricity jumping from a tungsten metal electrode to the metal surfaces you intend to weld usually aluminum. Stainless steel grows and warps excessively from heat. For these types of materials a tri gas mixture is recommended which consists of 90 helium 8 argon and 2 co2.

Tig can be used to weld copper titanium even two dissimilar metals and is handy for making tricky welds e g. Furthermore if you plan to weld stainless steel er308 er308l and er308lsi welding wire are best used. If this is a consideration make sure your tig welding machine has pulse welding capability. But in the case of 316l stainless you will need to incorporate a 316l wire.

It also forms the red blue and black coloring you re familiar with on welds. This is basically a common and unique process for joining stainless steel. To weld sheet metal with solid wires use electrode positive ep or reverse polarity. How to tig weld stainless steel.

S curves or welds on round things. This process also uses shielding gas against contamination but you can weld thinner metals more efficiently. The coloring is all from excess heat. 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.

When tig welding stainless steel pulse welding helps reduce distortion by minimising the heat going into the weld while simultaneously optimising penetration. When welding 304 stainless steel er308 er308l and er308lsi wires are compatible but for welding 316l stainless you need a 316l wire. Kevin stone is a senior fabricator who began applying his welding and drawing skills to the creation of massive stainless steel sculptures back in 2005. Tig welding stainless steel is performed by using a non disposable tungsten electrode with a tig welder for striking up the arc.

With these materials use a tri mix gas 90 helium 8 argon and 2 co 2.
