Module 1 – Squeeze-Type Resistance Spot Welding (STRSW) Process
This module describes the history of collision repair welding processes and defines the squeeze-type resistance spot welding (STRSW) process. The student will learn about the considerations for using STRSW and identify the stages of a resistance spot weld.

Module 2 - STRSW Equipment and Settings
In the second module, the student will learn about STRSW power sources and inverter-type equipment. This module covers the types of STRSW arm sets, electrode tips, electrode tip maintenance, and machine settings.

Module 3 – Making Resistance Spot Welds
This module explains how to prepare a panel for spot welding and provides information for panel fit-up and alignment of the electrode tips. It provides information on how to determine the correct pitch and edge distance for STRSW welds, and how to visually inspect and destructively test STRSW welds.

Module 4 – Weld Bonding
The final module provides an overview of the weld bonding process and how to prepare mating flanges for weld bonding. The student will learn how to make and inspect weld bonding test samples. Also included in this module are vehicle-maker recommendations for STRSW and how to choose STRSW equipment.
