Credits: 3

Course Description:

Students will study and demonstrate safety practices with Gas Metal Arc Welding (GMAW) and Flux Cored Arc Welding (FCAW). The GMAW and FCAW processes will be discussed in depth including the different type of modes of transfer available, shielding gases, and the different types of materials that can be welded. The differences in the electrode types of gas-shielded wires and self-shielded wires will be discussed, along with the types of shielding gases that are used. There will be discussions on the importance of how the welding process intersects with arc welding symbols and codes. There will also be a review of procedures used in visual inspections of welds. Time will be spent in the lab developing skills using GMAW and FCAW processes. Welds will be made in the flat, horizontal, vertical, and overhead positions. Written and fundamental tests will be completed in accordance with American Welding Society (AWS) codes and standards. Course Outcomes: 1. Demonstrate the proper use of Personal Protective Equipment (PPE) during welding. 2. Demonstrate safety habits consistent with industry standards and college policy. 3. Operate GMAW and FCAW equipment according to industry standards and practices 4. Examine the GMAW and FCAW applications used in current industry practices, 5. Differentiate GMAW and FCAW setup requirements and techniques from other welding processes. 6. Identify the common shielding gases, metals, and electrodes utilized with GMAW and FCAW processes. 7. Interpret arc welding symbols and codes in accordance with American Welding Society AWS standards. 8. Determine weld quality by following procedures for visual inspections of welds in accordance with American Welding Societ AWS standards. 9. Perform welds in the flat, horizontal, vertical, and overhead positions utilizing GMAW and FCAW. 10. (IL0: 4) Apply the appropriate power settings to specific types of modes of transfer,
