Abstract
For resistance-welding workpieces of metal, an electrode is pressed against superposed regions of the workpieces and an electric current is supplied to the superposed regions to heat the same due to an electric resistance of the workpieces. The electrode has a body having a tip end for pressed engagement with one of the workpieces, and a matrix of tapered teeth disposed on the tip end of the body except for a center of the tip end. The teeth define recesses therebetween. One of the recesses is positioned at the center of the tip end, and the teeth are progressively higher from an outer circumferential edge of the tip end toward the center thereof.
Claims11
An electrode for use in resistance-welding workpieces of metal by being pressed against superposed regions of the workpieces and supplying an electric current to the superposed regions to heat the superposed regions due to an electric resistance of the workpieces, said electrode comprising:
- a body having a tip end for pressed engagement with one of the workpieces;
- and
- a matrix of tapered teeth disposed on said tip end of said body except for a center of said tip end with recesses defined between said tapered teeth, one of said recesses being positioned at the center of said tip end, each of said teeth having respective heights defined from a base of the teeth to respective tips of the teeth, said heights of said teeth becoming progressively higher from an outer circumferential edge of said tip end toward said center thereof.
