scope:

This standard provides specifications on spot weld joints of low carbon steel, low alloy steel and stainless steel materials with panel thickness of 0.4mm ~ 5.0mm. Here, hardening agent, surface treatment agent, clad material and combination of different materials, whose tension strength of welded area is 25% or less of tension shear strength, are excluded.

PURPOSE

The purpose of this standard is to specify test procedure and assessment criteria on spot welded joints of metal materials used for motor vehicles.
