The American Welding Society (Miami, Fla.) released AWS D8.7M:2005, Recommended Practices for Automotive Weld Quality-Resistance Spot Welding. This document presents recommended practices and criteria for evaluating resistance spot welds typical of automotive sheet steel applications. It contains weld characteristics, metrics and test methods useful in evaluating spot welding quality on coated and uncoated automotive sheet steels of all strength levels and compositions. These test methods are designed to assess static and dynamic properties of automotive sheet steel.
