Performing AWS Bend Test
Mechanical testing can be done to determine the strength of the welding area. This test should be performed when
setting up parameters to assure a sound weld is being made.

The AWS Structural Welding Code D1.1-72 states: “Each welding unit before use in production shall be used to weld
two stud or shear connectors to separate material in the same general position (flat, vertical, overhead, sloping) and of
similar thickness. After being allowed to cool each stud shall be bent to an angle of 30 degrees from its original position
by striking with a hammer. If failure occurs in the weld zone of either stud the procedure shall be corrected and two
successive studs welded and tested.”
