Student Led Plug Welding Demonstration

In this ABRN How2 tip Preston and Tucker, collision repair students at Butler Community College, are doing a student led demonstration, demonstrating how to perform a plug weld using a MIG welder. Once welded, they demonstrate a destructive test method to determine if the plug weld passes the test.

A plug weld can replace the factory spot welds when repairing a vehicle in a body repair shop. Even if the shop is equipped with a resistance spot welder, there are some areas that are two difficult to reach with the spot welder. There may also be certain areas that plug welds are recommended by car manufacture.
