W-50 - Tensile Weld Tester

The W-50 Weld Tester is a destructive weld testing machine that incorporates compression, tensile, and bend testing in one complete unit. The W-50 is an invaluable asset to any training facility or commercial company that requires weld qualification.

The W-50 can do all the key destructive tests as specified by AWS, ASME, and API. The W-50 requires very little space since the unit sits horizontally. This machine is designed so the entire test procedure can be handled by one operator quickly and easily.
