Catalog Description

Formerly known as WELD 25
Prerequisite: Completion with grade of "C" or better or concurrent enrollment in WELD 5A
Hours: 72 (18 lecture, 54 laboratory)
Description:Students expand on knowledge and skills gained to perform structural plate welding using Shielded Metal Arc Welding (SMAW or Stick). Oxyacetylene Cutting (OAC) and Air Carbon Arc Cutting (CAC-A) are also performed. Intended as an intermediate level welding course for students following a career path in structural or pipe welding fields. Students are advised that WELD 5A and WELD 5B can be taken at the same time. (not transferable)

Course Student Learning Outcomes

  • CSLO #1: Apply knowledge of safety standards for both a learning environment and work site environment with focus on SMAW, plus CAC-C and track OFC cutting processes on plate.
  • CSLO #2: Define terms related to this course: open groove, low hydrogen exposure limit, air carbon arc gouging, inclination of axis.
  • CSLO #3: Demonstrate manipulative skills to prepare materials and deposit SMAW in 2G, 3G, 4G positions with both stringer and weaved techniques on carbon steel plate.
