Mandrel supported tensile test to evaluate weld bonding










Image Number 3 for United States Patent #6557421.

A tensile test apparatus and method for testing a circumferential weld on a tubular member wherein the tube region of the weld is completely supported by a mandrel and the tubular specimen is gripped on both sides of the weld along the specimen's longitudinal length with a very small separation distance between the tensile test grips. If there are any non-bonded defects in the weld, they are captured by the weld fracture surface as mesa or void features with an orientation different from that of a well bonded region.
