Course Details
Course Code:
WELD 217

Calendar Description:
This program focuses on affects of heating and cooling in welding, identifying aluminum and its alloys, and the grain structure of metals. This course is part of the three month, self-paced, Level 'B' Welding program. To complete the Welding 'B' Level program, students must complete P7 and 1 of Modules P8, P9, or P10. To advance to 'A' Level, P-10 must be completed. Students requiring additional time to complete may, with the approval of the instructor, purchase additional weeks of instruction.
