Course Description: This course covers shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and flux core arc welding (FCAW) processes on several pipe systems. A variety of materials and configurations on sub critical pipe welding (pressure and power systems, cross-country transmission, pipeline welding and water transmission pipe welding) will be used. Special attention and performance standards for the qualifications will be used from the following codes: American Petroleum Institute (API), American Welding Society (AWS) and American Society of Mechanical Engineers (ASME).
Objectives
Upon successful completion of this course, the student should be able to:
- Weld pipe and tube in 2G, 5G and 6G position using all the following processes: SMAW, GMAW, GTAW, and FCAW.
- Apply qualifications procedures of the API, AWS, ASME codes for certification.
- Follow procedures using the SMAW, GMAW, GTAW and FCAW welding processes meeting API, AWS, and ASME specifications for qualification of welding procedures and the welder.
