WLD 220 - Machine Tool Maintenance and Repair

3 Credit(s)

Prerequisite(s): WLD 113, and BT 114 or WR 121Z or designated placement, and MTH 60 or MTH 63 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 Level: Career/Tech Preparatory

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 solution 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 for equipment. (ILO: Communication)
CLO#5: Identify and explain maintenance requirements of general shop fabrication equipment (band saw, drill press, angle grinders, sanders, shears and ironworkers etc.). Follow appropriate recording procedures.
CLO#6: Independently demonstrate basic maintenance procedures on engine driven welder/generator machines.
