Abstract
A welding electrode according to the disclosure includes a body. A head is secured to the body and includes an aperture through which a pin extends. A polymer insulating sleeve is arranged between the pin and the head, for example. The sleeve material extends radially from an inner diameter to an outer diameter. The outer diameter engages the head, and the inner diameter is in close proximity to and engagement with the pin, which slides axially relative to the sleeve. The head and sleeve include first and second interlocking features that cooperate with one another to retain the sleeve in the aperture. The sleeve is arranged inboard from an outer face of the head, which is used to support a work piece.
Claims14
A welding electrode comprising:
- a body;
- a head secured to the body and including an aperture;
- a pin arranged within the body and extending through the aperture;
- and
- a polymer insulating sleeve arranged between the pin and the head, the sleeve extending radially from an inner diameter to an outer diameter that are respectively in contact with the pin and head.
A welding electrode comprising:
- a head including an aperture extending from an outer face to an inner face, the head including a first interlocking feature;
- and
- a insulating sleeve received within the aperture and including a second interlocking feature cooperating with the first interlocking feature, the insulating sleeve constructed from an insulating material that is in engagement with the head and extends radially inwardly to a pin support surface.
A method of manufacturing an electrode comprising the steps of:
- machining a head to include an aperture and a first interlocking feature;
- machining a sleeve to include a second interlocking feature;
- and
- inserting the sleeve into the aperture such that the first and second interlocking features engage one another in an interference fit.
