UNIVERSAL DEVICE FOR SEAM AND DOT ELECTROCONTACT WELDING Russian patent published in 2010 - IPC B23K11/06 B23K11/10 

FIELD: technological processes.

SUBSTANCE: invention may be used to recover and strengthen parts by method of seam and dot electrocontact welding. At one end of every of two electrode heads, there is a roller electrode mounted for seam welding, and at the other end - electrode for dot welding. Electrode heads are fixed on axes 1 of bar holds 2 fixedly by means of engaged sectors 3 and 4 arranged on bushing 5 of electrode heads and on axes 1 of bar holds. Sectors provide for fixation of electrode heads against undesirable axial motions in process of welding and their re-installation by means of 180° turn in plane perpendicular to axes of bar holds.

EFFECT: proposed design of device makes it possible to execute both seam and dot welding, at the same time electrode heads fixation rigidity is increased, and identical quality of parts welding is guaranteed.
