DEVICE FOR CONTACT POINT WELDING WITH COOLING ELECTRODE-CAP Russian patent published in 2017 - IPC B23K11/30 B23K11/10 

FIELD: electricity.

SUBSTANCE: electrode-cap is placed on the conical surface of the front part of the holder to form an axial gap between the bottom of the cavity of the electrode-cap and the front end of the holder. The coolant supply tube is installed with a side gap in the longitudinal channel of the holder sealed at its front end and open to the axial gap. On the conical surface of the holder, longitudinal grooves are provided that are open on one side to the axial gap, and an annular groove with a sealing element installed therein for sealing the mating surfaces of the holder and the electrode-cap, into which the longitudinal grooves of the holder on the other side thereof are exposed. The axial longitudinal channel of the holder is connected by transverse windows formed in the wall of the holder, with longitudinal and annular grooves. The coolant circulates along the longitudinal channel, the transverse windows, the outer grooves of the holder, the axial gap between its front end and the bottom of the electrode cavity and is withdrawn through the tube beyond the holder.

EFFECT: effective cooling ensures an increase in the resistance of the electrode-cap.
