ABSTRACT:
An apparatus and method for testing weld integrity is disclosed which is portable, self-contained, adaptable for field use in most locations, and can verify the integrity of attachment welds. The testing apparatus includes a cylinder or cylinders, attachable to the desired object to be tested on one end and to a cross bar on the other end, support beam or beams which, along with the cylinder or cylinders, support the test apparatus, a supply for pressurized fluid, and a control manifold for flow direction and pressure measurement. The pressurized fluid moves the cylinder shaft creating a load on the test piece. As the fluid pressure increases the cylinder shafts extract or retract and exert a required load on the test piece. The test piece is then inspected for breakage or damage such as deformation or attachment weld cracking.
