Abstract
Official abstract text for this publication.
In resistance welding, an end portion and a flange portion are welded together at contact surfaces thereof by applying a voltage between a first electrode and a second electrode while an inner casing and a main metal piece are pressed in directions toward each other. When a shearing stress due to the pressure is applied to a ceramic guide pin, the guide pin is more resistant to wear compared to a phenolic resin guide pin. In addition, a clearance is between a large-diameter portion of the guide pin and an inner surface of a guide-pin insertion hole. Accordingly, the guide pin is capable of tilting in the radial direction, so that the guide pin can tilt so as to partially absorb the shearing stress. Therefore, the guide pin is more resistant to breakage compared to a guide pin made of ceramic that is not capable of tilting.
First claim
Opening claim text (preview).
What is claimed is: 1. A resistance welding method for welding conductive cylindrical first and second members to each other in a coaxial manner by bringing end portions of the cylindrical first and second members into contact with each other, the resistance welding method comprising: providing a first electrode having an insertion hole and a columnar guide pin insertable into the insertion hole; positioning the guide pin and the cylindrical first member by inserting the guide p…
