Quality controlling method for welded joint in wire conductor connection, involves pressing end against surface such that opening is filled by line and determining quality of connection by comparison of filling degree of opening with value

摘要

The method involves providing a connection latch (12) with a passage opening (19) in a contact surface (18) lying against a connection line end. The end is pressed against the surface such that the opening is filled proportionately by a connection line. Quality of a wire conductor connection (13) is determined by comparison of filling degree of the opening with a reference value, where the opening has ramp shaped inner walls and width or diameter of the opening is 1.5 to 3 times of material thickness of the connection latch.
