Austenitic stainless steels are highly prone to distortion during welding due to their high thermal expansion, low thermal conductivity, and reduced yield strength at elevated temperatures. These properties cause significant localized expansion and uneven contraction, leading to residual stresses and warpage. To minimize distortion, welders can employ techniques like controlling heat input, optimizing welding sequences, using rigid fixturing, and in some cases, post-weld heat treatment. A tailored approach combining these methods is crucial for achieving sound and dimensionally accurate stainless steel weldments.
