Quizplus · Accepted Answer

Stainless steel should be thoroughly cleaned before welding to ensure the best quality weld. This can involve using acids (to remove rust and scale), alkalines (to neutralize acid residues and remove fats), and detergents (to remove oils and dirt). Each of these cleaning agents serves a different purpose and may be used in sequence to prepare the metal surface for welding.
