Patent ID: 7075028

Claim:
A method comprising: configuring an electrically conductive workpiece to define a weld region having an attachment surface which is configured for attachment to an electrically conductive support surface that is defined by a support arrangement; distributing a biasing force using a biasing force arrangement, at least partially around the weld region of the workpiece to 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 contacting the workpiece at said weld region using an electrode tip forming a distal end of an electrode in a way which provides for substantially compliant movement of the electrode tip with the weld region at least in directions that are generally parallel to the support surface while applying a welding current though said electrode, and while said biasing force arrangement applies said biasing force, so as to weld the attachment surface of the workpiece to the support surface.
