Break test consists of breaking a specimen on a strength testing machine by increasing the applied load until the specimen ruptures. The break surface is then observed to determine any defects such as cavities, non-metallic insertions, cracks, lack of fusion or incomplete fusion.
Break testing is among the test methods performed during a welder qualification exam.
Break tests are performed in conformity with the following standards:
PN-EN ISO 9606-1:2017-10 - Qualification testing of welders — Fusion welding — Part 1: Steels
PN-EN ISO 9017:2018-03 - Destructive tests on welds in metallic materials — Fracture test
