FIELD: welding.
SUBSTANCE: invention can be used for fabrication of reinforcement mesh by contact spot welding. Upper part of the electrode is made with widening, from the lower end of which a cylindrical cavity is formed, in which the working part of the electrode is fixed by means of bolts. At the bottom of the above cavity there made are transverse closed from the edges grooves separated by partitions forming the coolant circulation zone. Grooves, partitions with openings are made with possibility to direct coolant flow to central groove. In the central groove there is a longitudinal cavity of the upper part of the electrode, which is intended for removal of the heated coolant; at that, the coolant circulation zone is sealed with a sealing element.
EFFECT: collecting electrode provides symmetrical and uniform cooling of its end, which reduces wear and increases resistance of the electrode.
