Weld fracture test is performed to reveal embedded imperfections such as lack of fusion, incomplete penetration, cracking due to inadequate width to height ratio, slag inclusions and porosity.

LMATS  Melbourne and Sydney laboratories performs these tests in accordance with AS 2205.4.1, AS 2205.4.2, ISO 9017, ASME IX QW 182, AS 1665 and AS 2885.2 and similar international standards.
