How to tig weld stainless steel sheet.

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. Tig stands for tungsten inert gas which is a welding technique done with the help of tungsten electrode for heating different metals. But in the case of 316l stainless you will need to incorporate a 316l wire. Tig can be used to weld copper titanium even two dissimilar metals and is handy for making tricky welds e g.

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. With these materials use a tri mix gas 90 helium 8 argon and 2 co 2. If this is a consideration make sure your tig welding machine has pulse welding capability. It also forms the red blue and black coloring you re familiar with on welds.

When tig welding stainless steel pulse welding helps reduce distortion by minimising the heat going into the weld while simultaneously optimising penetration. For these types of materials a tri gas mixture is recommended which consists of 90 helium 8 argon and 2 co2. Furthermore if you plan to weld stainless steel er308 er308l and er308lsi welding wire are best used. Tig welding stainless steel is performed by using a non disposable tungsten electrode with a tig welder for striking up the arc.

To weld sheet metal with solid wires use electrode positive ep or reverse polarity. Tig generates heat via an arc of electricity jumping from a tungsten metal electrode to the metal surfaces you intend to weld usually aluminum. Tig welding is one type of welding amongst a few choices you have mig stick oxyacetylene etc. When welding 304 stainless steel er308 er308l and er308lsi wires are compatible but for welding 316l stainless you need a 316l wire.

This is basically a common and unique process for joining stainless steel. Stainless steel grows and warps excessively from heat. It is ideally preferred where the chicago welder fails because of its limitation in doing the stainless steel soldering job. This process also uses shielding gas against contamination but you can weld thinner metals more efficiently.

The coloring is all from excess heat.
