ROLL ELECTRODE FOR ELECTRIC CONTACT WELDING

摘要

FIELD: electricity. ^ SUBSTANCE: roll electrode is arranged with flat working surface in the form of packet electrode and from materials with different conductivity and hardness that are assembled in packet so that conductivity is reduced and hardness is increased from the center to the edge. ^ EFFECT: improvement of uniformity of current density distribution in contact area of electrode-part and uniformity of wear of electrode working surface. ^ 2 dwg
