Abstract
PURPOSE: To perform captioned welding at low cost, preventing inclination of thread part, by inserting a cross-recessed flush head screw into the hole in a work, passing the thread part of flush head screw into the guide tube inserted in the hole in the lower electrode, and pressurizing and feeding power by the upper electrode.
CONSTITUTION: A guide tube 3 made by forming electric insulating films on the inner and outer surfaces of a stainless steel tube is inserted into a hole 2a in a lower electrode 2. A thin sheet work 4 is disposed on this electrode 2, and the hole 4a in the work 4 is set to coincide with the hole 3a in the tube 3. A flush head screw 5 with cross recess 6 is inserted into the hole 4a in the work 4, and the taper surface 5b of the flush heat screw 4 is placed in linear contact with the edge of the hole 4a, and the thread part 5c is positioned in the hole 3a. By pressurizing the upper electrode 1, power is supplied to the electrodes 1, 2. Since the head part 5a of the flush head screw 5 is relieved nearly uniformly by the cross recess 6, the whole head part 5a softens, and is crushed on the work 4 so as to be deposited uniformly with the work 4. The thread part 5c is accurately projected because its inclination is defined by the tube 3.
