Catalog Description Formerly known as WELD 20 Advisory: Concurrent enrollment in WELD 1A or previous welding experience Hours: 72 (18 lecture, 54 laboratory) Description: An introduction to the principles of shielded metal arc welding (SMAW), setup/use of SMAW equipment, and safe use of tools and equipment including oxyacetylene cutting. Provides instruction in welding carbon steel weld joints in various positions. This is a required foundation welding technology course for students who wish to pursue a career in structural or pipe welding outdoors at various construction sites. (C-ID WELD 101X) (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 Shielded Metal Arc Welding plus Oxyacetylene Cutting, to perform student assignments. CSLO #2: Define terms related to this course; constant current output, duty cycle, fast freeze electrode, fill freeze electrode, low hydrogen, stringer or weave manipulation, regulator, undercut, weld toe and fillet weld size. CSLO #3: Demonstrate manipulative skills using Shielded Metal Arc Welding with stringer and weave bead techniques on carbon steel plate in flat, horizontal, vertical and overhead fillet weld positions. CSLO #4: Analyze the relationship between heat input and metal fusion. Explain how current setting, arc length, travel and work angles, travel speed and electrode manipulation affect the heat input in a weld puddle. CSLO #5: Demonstrate safe handling and proper manipulative skills using Oxyacetylene Cutting to cut steel.
