Patent ID: 7126078

Claim:
A resistance spot welding method for fixedly attaching an attachment surface of an electrically conductive workpiece to an electrically conductive support surface that is defined by a support arrangement, said method comprising: configuring a biasing force arrangement having a biasing tip for distributing a biasing force at least partially around a weld region of the workpiece to selectively bias the attachment surface of the workpiece against said support surface in a way which at least resists welding induced movement of the workpiece relative to the support arrangement and defining a through hole in the biasing force arrangement having an exit opening, formed within the biasing tip, that is at least generally aligned with the weld region when the biasing force arrangement delivers said biasing force around the weld region; providing an elongated, flexible electrode, having an overall length between a first end and a second, opposing end; and resiliently urging the electrode into the through hole to cause at least a first portion of the overall length of the electrode to be received in the through hole in a way which supports the first end of the electrode, terminating in an electrode tip for emerging from the exit opening to contact the workpiece at said weld region, while applying a welding current through said electrode tip so as to weld the attachment surface of the workpiece to the support surface.
