In particular this technique is used for welding exhaust pipes made from alloys such as stainless steel.
Tig welding stainless steel exhaust pipe.
Those of you working on stainless steel exhaust pipes a dc current tig welder can be an excellent choice.
Tig welders are similar to mig in that they need a supply of shielding gas connected to the welder.
By using tig welder you can use the right heat to weld the exhaust pipe and get the best welding result.
Firstly tig welding has zero tolerance of dirt oils paint and rust.
Your base surface should be completely free of oils rust paint and dirt.
You can use this technique to weld exhaust pipes made from sensitive alloys like stainless steel.
Hard to use during welding.
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.
So first thoroughly clean the tubing and ensure no dirt or oil residue is left.
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.
However instead of automatic wire feeding tig systems use a rod that you have to melt into the seam with a hot arc.
The first part is cleaning the tubing and ensuring that no residues are left.
When tig welding exhaust pipe care must be taken.
Tig welding is ideal for doing weld exhaust pipe properly.
The magnet stuck to the mig weld strongly letting me know for sure that the weld was carbon steel.
However you must take extra precaution to tig weld your exhaust pipe.
Tig welding is traditionally used for welding stainless steel tube and pipe and remains the optimal solution for extremely high purity applications on tube or pipe at or below 6 inch diameter and schedule 10 wall thickness.
