Post Weld Treatment

The welding induces undesirable residual stresses and reduces corrosion resistance. Stress relieving, annealing or solution annealing are the treatments recommended for weldments before putting them to use. Weld decay is a common welding defect in stainless steel which is caused by precipitation of carbide of chromium in the weld region and HAZ. The result of this precipitation is great susceptibility to intercycstalline cracking when a corrosive media comes in contacts.
