Welding procedure specifications (WPS) allow welders to consistently produce welds that meet desired requirements without any rework. However, the nature and use of a WPS, and its supporting procedure qualification record (PQR), are commonly misunderstood. This online course provides a comprehensive overview of these documents in an engaging and easy-to-understand multimedia format. Topics include: the format and function of a WPS and a PQR; the different types of WPSs; essential and nonessential variables for arc welding, oxyfuel welding , resistance welding and brazing procedure specifications; the procedure qualification process; the information included on a PQR; and common nondestructive and destructive tests.
