7 Most Common Welding Defects, Causes and Remedies
Slag is a vitreous material that occurs as a byproduct of stick welding, flux-cored arc welding and submerged arc welding. Is can occur when the flux, which is the solid shielding material used when welding, melts in the weld or on the surface of the weld zone. Causes: Improper cleaning. The weld speed is too fast.

Best Methods for Welding Stainless Steel (With PDF)
Also known as Tungsten Inert Gas Welding or TIG welding, the welding of stainless steel by GTAW uses Argon or any other inert gas to protect the welding zone from atmospheric contact. An intense electric arc generated between the non-consumable tungsten electrode and the SS workpiece creates the necessary heat for welding.

Argon is also used as back side shielding gas, mainly in welding of stainless steels, aluminum alloys and reactive metals. Flow rates of shielding gases depend on weld thickness, being 4 - 10 l/min for argon and 10 - 15 l/min for helium, because it is lighter than argon, and consequently less effective in shielding purposes [ 28] .
