FIELD: quality control of welded and soldered joints of different materials, possibly in different branches of industry.
SUBSTANCE: process comprises steps of forming protrusion in allowance zone on one of materials to be welded and forming in the form of ring allowance zone and part of joint adjacent to said protrusion. Axis of said ring coincides with axis of blank. Load is applied to protrusion for destruction of part of welded joint arranged in zone of allowance. According to load value welded joint quality is evaluated. It provides possibility for quality control of welded and soldered joints with cross arrangement of layers due to creation of out-of-center tension in part of butt joint arranged in allowance zone.
EFFECT: improved reliability of quality control process.
