How To Tig Weld Stainless Steel Sheet

It also forms the red blue and black coloring you re familiar with on welds.

How to tig weld stainless steel sheet.

This process also uses shielding gas against contamination but you can weld thinner metals more efficiently. Tig welding stainless steel is performed by using a non disposable tungsten electrode with a tig welder for striking up the arc. Tig stands for tungsten inert gas which is a welding technique done with the help of tungsten electrode for heating different metals. This is basically a common and unique process for joining stainless steel.

Tig welding is one type of welding amongst a few choices you have mig stick oxyacetylene etc. It is ideally preferred where the chicago welder fails because of its limitation in doing the stainless steel soldering job. How to tig weld stainless steel. 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.

S curves or welds on round things. But in the case of 316l stainless you will need to incorporate a 316l wire. With these materials use a tri mix gas 90 helium 8 argon and 2 co 2. To weld sheet metal with solid wires use electrode positive ep or reverse polarity.

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. If this is a consideration make sure your tig welding machine has pulse welding capability. When tig welding stainless steel pulse welding helps reduce distortion by minimising the heat going into the weld while simultaneously optimising penetration.

The coloring is all from excess heat. 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. The tig option can be deployed for doing the stainless steel welding task. 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.
