Welding Test pieces

We are providing welding test pieces for ISO24394, ASME, AWS, DIN

  1. ISO 24394 Welding for aerospace applications:

Welding for aerospace applications –Qualification test for welders and welding operators –Fusion welding of metallic components

Current ISO 24394:2018  is second edition issued in 2018-12 (last is ISO 24394:2008 + Amd. 1:2013, DIN ISO 24394:2013-12)

7 Test pieces  

Test pieces (see Table 6) shall be applied according to the required welder qualification test, see 4.1.1.
