There are 3 common strategies to understand to weld stainless steel. SMAW (shielded metal arc) or rod welding, GMAW(commonly known as Mig welding (metal inert gas), and GTAW (tungsten inert gas) or Tig welding.
Stick or Arc welding.
The approaches to weld stainless with a arc welder very little to this of steel. Normally a little indicator stainless steel electrode can be utilized for arc welding stainless steel. There are many online sources where you can get the info about footvalve stainless.
A security note of warning, such as mild steel there’s a layer of slag made onto a finished bead, using mild steel that the slag needs burning off, nevertheless, stainless slag has a propensity to ‘stand’ off since it warms.
This may result in significant eye damage consequently always use eye protection utilizing stainless electrodes. Employing arc equipment is a Relatively Simple way to Learn to weld stainless steel
Mig welding stainless steel.
Again a similar procedure used on light steel. Evidently, you’ll have to swap the mig welding cable for stainless steel cable. This is normally available in 304 and 316 grades.
Use 316-grade stainless steel wires in high corrosion regions and also for marine uses. You’ll also have to use pure argon gas rather than c02 that’s used for mild steel. Mig welding is not uncommon in metal manufacturing shops.
The best way to Tig Stainless.
This way has become the toughest to understand to weld stainless steel, but in my view, it’s by far the most gratifying and supplies a pristine joint between the base metal and metal alloy.
