Spot welding electrode
First Claim
Patent Images
1. A spot welding electrode comprising:
- a plurality of co-axially spaced first sections, each having a first predetermined sized cross section;
a plurality of second sections each integrally and co-axially formed with and interposed between adjacent first sections, each of the second sections having a second predetermined sized cross section smaller than the first cross section of the first sections;
the outer side surfaces of the second section forming undercut areas between the outer side surfaces of adjacent first sections, the outer side surfaces of the second sections serving as cleavage surface to remove excess material formed at the peripheral edges of the adjacent first section caused by deformation of successive first sections during repeated welding operations.

Abstract
A spot welding electrode includes a plurality of alternating, co-axially first and second sections, the first sections having a first predetermined sized cross section. The second sections have a second predetermined sized cross section smaller than the cross section of the first sections. The outer sides of the second sections form undercut areas between the outer sides of adjacent first sections. The outer sides of the second sections act as cleavage surfaces which remove excess material formed at the peripheral edges of the adjoining first sections caused by successive deformation of the first sections during repeated welding operations.

11. A spot welding electrode cap removably emplaceable on a hollow holder comprising;
-
alternating, co-axially aligned first and second sections, the first sections having a first predetermined sized cross section, the second sections having a second predetermined sized cross section smaller than the cross section of the first sections; the outer surfaces of the second sections forming undercut areas between the outer surfaces of adjacent first sections, the outer surfaces of the second sections functioning as cleavage surfaces which remove excess material formed on the peripheral edges of adjacent first seconds during repeated welding operations; and an end portion having the first and second sections formed at one end, the end portion having an internal cavity for coolant fluid flow.
