When tig welding stainless steel pulse welding helps reduce distortion by minimising the heat going into the weld while simultaneously optimising penetration.
How to tig weld stainless steel sheet.
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.
If this is a consideration make sure your tig welding machine has pulse welding capability.
When welding 304 stainless steel er308 er308l and er308lsi wires are compatible but for welding 316l stainless you need a 316l wire.
Stainless steel grows and warps excessively from heat.
With these materials use a tri mix gas 90 helium 8 argon and 2 co 2.
S curves or welds on round things.
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.
This is basically a common and unique process for joining stainless steel.
This process also uses shielding gas against contamination but you can weld thinner metals more efficiently.
Tig can be used to weld copper titanium even two dissimilar metals and is handy for making tricky welds e g.
For these types of materials a tri gas mixture is recommended which consists of 90 helium 8 argon and 2 co2.
Tig welding is one type of welding amongst a few choices you have mig stick oxyacetylene etc.
Furthermore if you plan to weld stainless steel er308 er308l and er308lsi welding wire are best used.
But in the case of 316l stainless you will need to incorporate a 316l wire.
How to tig weld stainless steel.
The coloring is all from excess heat.
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.
To weld sheet metal with solid wires use electrode positive ep or reverse polarity.
It also forms the red blue and black coloring you re familiar with on welds.
Tig welding stainless steel is performed by using a non disposable tungsten electrode with a tig welder for striking up the arc.
The tig option can be deployed for doing the stainless steel welding task.
