Abstract
PURPOSE: To improve the bonding strength of weld zone by providing the curved surface form ridge part intersecting orthogonally with the axial direction of an Mo wire on the contact surface of a welding electrode end in contact with an Mo plate at the time of welding the Mo wire and Mo plate by supplying electric current under pressure thereto by the electrodes from their above and below.
CONSTITUTION: An Mo wire material A and Mo plate material B are contacted. While they are being pressed by upper and lower electrodes 1, 2, electric current is flowed between the electrodes 1, 2 to weld the Mo wire A and Mo plate B. At this time, the end face 2a of the lower electrode 2 in contact with the Mo plate B is formed to the semicircular shape of a radius of curvature R. Hence, it has a ridge part 3 in the direction orthogonal to the axial direction of the Mo wire A. When pressure is applied and electric current is supplied by the electrodes 1, 2 in this state, the central part of the contact area D of the Mo wire A and Mo plate B recrystallizes and has smaller mechanical strength but in the peripheral part the rate of recrystallization is less becuase contact resistance is smallest in the central part and becomes gradually large in the periperal part thereof, thus the weld zone of high mechanical strength is formed.
