Description: Focus on advanced Shielded Metal Arc Welding (SMAW) for out-of-positions welding. This will include a focus on weld joint design and fit-up, weld quality, and an introduction to destructive and non-destructive testing. Welding will include AWS typical groove welds in the flat, horizontal, vertical, and overhead positions per AWS D1-1 Guided Bend Test with an emphasis on proper use and care of equipment and safety procedures. Prerequisite(s): Specialization # 1; WLD 121, 122, 222, or instructor consent.

Measurable Student Learning Outcomes
1. (Application Level) Explain and demonstrate safe working habits and procedures within a lab setting related to the welding trades.(CSLO 2)

2. (Synthesis Level) Use the fundamental techniques developed to become certified in the SMAW process to the AWS structural code.

3. (Evaluation Level) Explain and demonstrate how to evaluate weld discontinuities including undercut, overlap, porosity, and excessive reinforcement. (CSLO 2,3)

4. (Application Level) Apply the use of weld procedure specifications to base metal and filler metal selections, as it relates to welded joint designs. (CSLO 2,3)

5. (Synthesis Level) Develop proper techniques and utilization of Oxyfuel, Plasma, and Carbon Arc Cutting for preparation of welder qualification bend testing.(CSLO 2,3)

5. (Synthesis Level) Strengthen and develop advanced welding techniques by performing AWS typical groove welds in the flat, horizontal, vertical, and overhead positions, with emphasis on safety and proper use of equipment. (CSLO 2,3)

6. (Evaluation Level) Detect and assess the cause of weld defects: slag inclusions, porosity, overlap, lack of fusion, and undercut, by performing destructive testing. (CLSO 2,3)

7. (Application Level) Explain and demonstrate proper weld techniques and how to avoid weld defects in groove welds. (CSLO 2,3,4)

8. (Synthesis Level) Certify to AWS D1.1 Structural code through successful completion of welder qualification bend testing. (CSLO 2,3)
