Module 1 – Weld Removal and Replacement
The class opens by providing the student with an understanding on removing and replacing spot welds on a collision-damaged vehicle. The instructor will cover different options for replacing spot welds, such as repair spot welds, GMA (MIG) plug welds, and MIG brazing, which is gaining in popularity among vehicle makers. This module will also cover considerations for replacement at factory seams, such as removing parts for access or protection, the importance of corrosion protection. This module also contains interactive exercises that stress the importance of locating and using vehicle maker repair information.

Module 2 – Part Replacement at Factory Seams
The class continues by using actual vehicle maker procedures for replacing parts at factory seams and also explores some of the reasons why some parts need to be completely replaced. The class will also discuss situations that technicians may encounter, such as materials other than steel and how to work around, and with, sensors.

Module 3 – Separating Assemblies
The final module in the class will detail information on disassembling an assembly at the factory seams, comparing it against installing a complete part assembly. Also part of the discussion will be considerations for disassembling an assembly when the vehicle maker doesn’t provide procedures for doing so, or warns against it altogether. The instructor will provide information on what factors go into the decision for separating an assembly.
