Course Description: This is a supervised lab experience for pipe and tube welders. Students will practice skills in shielded metal arc welding (SMAW), gas metal arc welding (GMAW), flux core arc welding (FCAW), gas tungsten arc welding (GTAW), oxyacetylene welding (OAW), and oxy-fuel cutting (OFC) processes on several piping systems. Performance standards will meet the American Petroleum Institute (API) 1104 and American Society of Mechanical Engineers (ASME) Section IX. This course may be repeated to a maximum of 1.00 units to complete the entire curriculum of the course. Pass/No Pass only. Open Entry/Open Exit.
Objectives
Upon successful completion of this course, the student should be able to:
- Follow proper safety protocols when operating welding and cutting equipment.
- Cut, prepare, and weld various pipe joint designs.
- Follow procedures using the OAW, SMAW, GMAW, FCAW, and GTAW welding processes meeting API and ASME specifications for qualification.
