This SAE Recommended Practice provides a minimum standard for evaluating squeeze-type resistance spot welding (STRSW) equipment and minimum weld performance criteria for two-sided automotive collision repair welding. This document contains several standardized test methods that are designed for evaluating equipment performance in a laboratory environment.

This SAE Recommended Practice provides manufacturers of STRSW equipment with minimum performance criteria for collision damage repairs. Collision repair centers and related businesses will also benefit by having a guideline for selecting STRSW equipment that meets this minimum performance criteria.
