AWS D1.1 Welding Qualification
AWS D1.1
WELDING PROCEDURE AND QUALIFICATION
AWS D1.1 refers to the American Welding Society's (AWS) structural welding code for steel. It provides guidelines for welding procedure and performance qualification in steel construction.
Welding procedure qualification is the process of demonstrating that a particular welding process can produce welds that meet the specified requirements. This is typically done by welding test coupons, which are then evaluated to determine if the welds meet the acceptance criteria. The acceptance criteria can include factors such as weld penetration, fusion, and bead appearance.
Performance qualification is the process of demonstrating that a welder or welding operator is capable of producing acceptable welds. This is typically done by having the welder or operator complete a test coupon using the approved welding procedure. The coupon is then evaluated to determine if the welds meet the acceptance criteria.
AWS D1.1 provides specific requirements for welding procedure and performance qualification, including the types of welding processes that can be used, the test coupon dimensions and preparation, and the acceptance criteria for the completed welds. It also includes information on re-qualification and the requirements for record keeping.
In summary, AWS D1.1 provides a comprehensive guide for welding procedure and performance qualification in steel construction, ensuring that welds meet the necessary quality and safety standards.
