Abstract
PURPOSE: To subject the outside equipment and the cap to resistance welding completely in a short time without weld defects and appearance defects, by bringing a pair of taper electrodes into contact with the cap and by supplying power while rotating it, for welding between the outside equipment for semiconductor element and the cap.
CONSTITUTION: Outside equipment main body 1 incorporating the semiconductor element and so on is fixed onto rotary table 3. After cap 2 is overlapped onto outside equipment main body 1 and is fixed, a pair of electrodes 5 and 6 of the conical roller form are brought into contact with cap 2. A voltage is applied to both electrodes 5 and 6 to weld the contact part between cap 2 and outside equipment main body 1 due to resistance heating. Table 3 is rotated half simultaneously with applying of the voltage to weld all of circumferences of cap 2 and outside equipment main body 1. In this case, the cap edge part moves vertically along the taper part of electrodes 5 and 6 to adjust the interval between electrodes 5 and 6 automatically, and thus, welding superior in appearance is performed without generation of the arc.
