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

FIELD: electricity.

SUBSTANCE: holder has a cavity under the coolant supply tube and a transverse window connected to the cavity for removing the coolant. The electrode-cap is mounted on the front of the holder with a clearance relative to its end. There is a cap in the rear part of the holder, in the cavity of which the rear end of the tube is fixed. The hollow cap has a longitudinal window for the supply of the coolant and is installed in the cavity of the rear part of the holder through the sealing elements sealing the gap between the surfaces of the tube and the cap. At the front end of the holder, the inner chamfer is made, and the end of the tube has a shape corresponding to the shape of the said chamfer and the cavity of the electrode-cap. The tube is installed in contact with the bottom of the electrode-cap cavity, and transverse grooves are made on the front of its front part.

EFFECT: increasing the resistance of the electrode-cap working surface by eliminating the stagnant zone with the coolant in its cavity.
