WLD 220 - Machine Tool Maintenance and Repair

WLD 113  

MTH 60  or MTH 102CT  or designated placement

WR 121Z  or designated placement

Course Description: Focuses on troubleshooting problems commonly encountered in welding and fabricating equipment. Students will learn basic electrical principles and apply them to simple repair tasks on welding power sources. Removal and replacement of mechanical components on welding equipment and shop equipment (band saws, shears, drill presses, etc.) will round out the students’ ability to function independently in the shop setting.

Course Learning Outcomes:

• CLO#1: Explain the basic electrical concepts associated with welding power sources, include possible hazards encountered during troubleshooting and how to avoid them.
• CLO#2: Troubleshoot and prescribe repair solutions for power sources commonly used in Shielded Metal Arc Welding.
• CLO#3: Troubleshoot and repair power sources commonly used in Gas Metal and Gas Tungsten welding equipment.
• CLO#4: Demonstrate basic maintenance procedures on SMAW, GMAW and GTAW equipment including proper maintenance records. (ILO: Communication)
• CLO#5: Follow proper maintenance procedures of general shop fabrication equipment (e.g., band saws, drill press, angle grinder, sander, shears, ironworker), including documenting maintenance.
• CLO#6: Independently demonstrate basic maintenance procedures on engine driven welder/generator machines.
