A. Bend Test
Repeatedly bend the stud away from its axis until failure occurs.
B. Torque Test - Threaded Studs
Twist the stud to point of failure. Apply a twisting tensile load by
using a collar, washer and nut.
C. Test Results
In an acceptable weld, failure will occur in the stud material or
tear out of a thin base plate. Failure in the weld requires adjust-
ment of procedure, weld time, weld current, or gun setup.
