WELD-262 Advanced Multi-Process Pipe Welding

Credits 4 / 6 Contact Hours
Pre-requisite: Placement into ACRD-080; WELD-260; and WELD-261 or WELD-272.
Students will further develop their Shielded Metal Arc Welding (SMAW), Gas Metal Arc Welding (GMAW), and Gas Tungsten Arc Welding (GTAW) skills by learning the American Society of Mechanical Engineers (ASME) Section IX & American Welding Society (AWS) D1.1 codes and standards and applying them to welds being performed. Students will create open root groove welds on carbon steel pipe using SMAW, GMAW, and GTAW. All welding will be performed in 2G, 5G, and 6G positions. Students
will be tested to meet qualification requirements for AWS D1.1 Prequalified Welding Procedure Specifications (WPS).
