WLD 224 - Pipe Welding 3 - Downhill
Credits: 3
2 Lecture Hours 2 Lab Hours
Prerequisites: WLD 223
Description
This course provides students with knowledge and skills to prepare for The American Petroleum Institute (API) downhill shielded metal arc pipe welding process and certification. This process is employed by the Marcellus Shale industry to connect natural gas cross country transmission pipelines. Students are introduced to the branch tee takeoff, which includes laying out, cutting and welding. The testing fee for the downhill shielded metal arc pipe welding certification is added to this course.
Learning Outcomes
Upon successful completion of the course, the student will:
- Perform proper pipe welding techniques to the downhill process using specialized electrodes.
- Fabricate a shielded metal arc weld on 6” pipe in a downhill fixed 5G position.
- Perform a shielded metal arc weld on 6” pipe in a downhill fixed 6G position.
- Validate the API downhill welding process required for the pipe certification.
- Design a branch tee takeoff cut and weld.
Listed Topics
- Downhill welding process
- Specialized electrodes for downhill welding positions
- API downhill welding test
- Layout, cut and fit of pipe sections
- Weld branch tee takeoff
