AWS- D8.9M:2012 Test Methods for Evaluating the Resistance Spot Welding Behavior of Automotive Sheet Steel Materials
D8.9M:2012 Test Methods for Evaluating the Resistance Spot Welding Behavior of Automotive Sheet Steel Materials, presents standard test methods for evaluating the resistance spot welding behavior of automotive sheet steels. The document contains a number of tests and test methods useful in determining the resistance spot welding performance of coated and uncoated automotive sheet steels of all strength levels and compositions.
The test methods are designed to assess current range, electrode endurance, and weld properties of automotive sheet steels. The weld property tests include tests for hold time sensitivity, weld hardness, shear tension strength, and cross tension strength.
