AWS D1.6, the Structural Welding Code for Stainless Steel, focuses on the structural integrity of welds on stainless steel alloys. It allows for cost-saving prequalified welding procedure specifications (WPSs), similar to AWS D1.1 for carbon steel. Using prequalified WPSs involves adhering to guidelines for welding process, base and filler metals, temperature, and joint type. While advantageous, users must own the code and ensure their applications align with its structural focus, as engineers are responsible for additional requirements like corrosion resistance.
