Abstract
A welding stud is attachable to a workpiece at a work end portion shaped for enhanced attachment strength with the workpiece. The welding stud has a portion of reduced thickness along a body portion between the work end portion and a retaining collar. The reduced thickness portion is furnished to yield or bend in the event of contact by some other body or piece and preserve the integrity of the attachment weld. The work end portion may also have an enlarged contact face with increased surface area for forming the weld.
Claims18
A welding stud for a stud welding gun to attach a component to a workpiece, comprising:
- a connector head at one end of the stud for fitting into the welding gun;
- a collar formed along an intermediate portion of the stud for retaining the component on the workpiece when the stud is attached;
- a work end for welding attachment to the workpiece;
- an intermediate body portion extending between the work end and the collar, the intermediate body portion having a reduced thickness shaft section along a portion of its extent between the work end and the collar, the reduced thickness shaft section having lower yield strength allowing the stud to yield and preserve the weld of the stud to the workpiece.
A welding stud for a stud welding gun to attach a component to a workpiece comprising:
- a connector head at one end of the stud for fitting into the welding gun;
- a collar formed along an intermediate portion of the stud for retaining the component on the workpiece when the stud is attached;
- a work end for welding attachment to the workpiece;
- a body portion extending between the work end and the collar;
- an end flat surface formed on the work end and having an enlarged contact face with increased surface area for forming the weld;
- and
- a shoulder surface formed rearwardly of the enlarged contact face of the end flat surface and tapering inwardly to the body portion.
A welding stud for a capacitor stud welding gun to attach a component to a workpiece, comprising:
- a connector head at one end of the stud for fitting into the welding gun;
- a collar formed along an intermediate portion of the stud for retaining the component on the workpiece when the stud is attached;
- a work end for welding attachment to the workpiece;
- an intermediate body portion extending between the work end and the collar, the intermediate body portion having a reduced thickness shaft section along a portion of its extent between the work end and the collar, the reduced thickness shaft section having lower yield strength allowing the stud to yield and preserve the weld of the stud to the workpiece;
- an end flat surface formed on the work end and having an enlarged contact face with increased surface area for forming the weld;
- and
- a shoulder surface formed rearwardly of the enlarged contact face of the end flat surface and tapering inwardly to the intermediate body portion.
