WELD 2510 Pipe Welding 1

This course provides pipe weld training using Shielded Metal Arc Welding (SMAW) process to develop the skills necessary to produce high quality welds on carbon steel pipe. Topics include: safety and health of welders in the pipe industry, review of oxyacetylene torch cutting, proper setup and use of pipe beveling equipment, and the use of mathematical equations to layout branch patters for pipe. Prerequisite: Completion of WELD 1610, WELD 1710, and WELD 1750. (2 lect., 4 lab)
