How To Tig Weld Stainless Steel Sheet

This process also uses shielding gas against contamination but you can weld thinner metals more efficiently.

How to tig weld stainless steel sheet.

The tig option can be deployed for doing the stainless steel welding task. Furthermore if you plan to weld stainless steel er308 er308l and er308lsi welding wire are best used. Stainless steel grows and warps excessively from heat. 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. It is ideally preferred where the chicago welder fails because of its limitation in doing the stainless steel soldering job. Tig generates heat via an arc of electricity jumping from a tungsten metal electrode to the metal surfaces you intend to weld usually aluminum. When welding 304 stainless steel er308 er308l and er308lsi wires are compatible but for welding 316l stainless you need a 316l wire.

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. To weld sheet metal with solid wires use electrode positive ep or reverse polarity. With these materials use a tri mix gas 90 helium 8 argon and 2 co 2.

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. Tig welding stainless steel is performed by using a non disposable tungsten electrode with a tig welder for striking up the arc. How to tig weld stainless steel.

S curves or welds on round things. The coloring is all from excess heat. Tig welding is one type of welding amongst a few choices you have mig stick oxyacetylene etc. This is basically a common and unique process for joining stainless steel.

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.
