Course Description: This course teaches 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. A variety of materials and configurations on sub-critical pipe welding to include pressure and power systems, cross-country transmission, water transmission and pipeline welding will be studied. Special attention and performance to the American Petroleum Institute (API) 1104 and American Society of Mechanical Engineers (ASME) Section IX code specifications for certification will be practiced. Intense training in pipe fitting, measurements, marking and layout tools used in the pipe welding industry will be stressed. Techniques of layout, cutting, fitting, and welding of various pipe joint designs will be performed.
Objectives
Upon successful completion of this course, the student should be able to:
- Correctly utilize the tools used in pipe layout and fitting.
- Layout various pipe joint designs.
- Cut, prepare, and weld various pipe joint designs.
- Layout and cut eccentric and concentric reducers.
- Apply qualification procedures of the API and ASME for certification.
- Follow procedures using the OAW, SMAW, GMAW, FCAW, and GTAW welding processees meeting API and ASME specifications for qualification of welding procedures and the welder
