We offer comprehensive assistance in developing and obtaining qualified WPQR welding technology and the organization of welders' examinations at the production plant of the commissioning party.
Qualification of WPQR welding technology is divided into stages:
- analysis of welding production - determination of variables such as types of welded materials, their thickness, types of joints, welding positions and such like,
- selection of the appropriate test connector,
- preparation of the initial welding technology manual – pWPS,
- welding of specimen joint,
- non-destructive and destructive test of the test connector,
- issue of technology qualification protocol by the notified body – WPQR,
