WLD 121 Shielded Metal Arc Welding I
Credit Hours:  3
Effective Term: Fall 2017
SUN#: None
AGEC: None  
Credit Breakdown: 2 Lectures, 3 Labs
Times for Credit: 1
Grading Option: A, B, C, D, F

Description: Focus on the Shielded Metal Arc Welding (SMAW) process using DCEN, and DCEP modes. Skills include basic equipment set-up, electrode selection, proper arc starts, re-starts, and terminations, and basic Oxy-Fuel cutting, and material identification. Welding experiences with overlap padding in the flat and horizontal positions are provided. Also covered are AWS typical fillet and lap joint designs in the flat and horizontal positions with an emphasis on proper use and care of equipment and safety procedures.

Prerequisites: None

Corequisites: None

Recommendations: None

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