Abstract
Attaching an attachment surface of an electrically conductive workpiece to an electrically conductive support surface is described. In one aspect, a biasing force is distributed at least partially around a weld region of the workpiece to urge the attachment surface of the workpiece against the support surface in a way which at least resists welding induced movement of the workpiece relative to the support arrangement. An electrode arrangement, having an electrode tip, contacts the workpiece to provide for substantially compliant movement of the electrode tip against the weld region in directions that are parallel to the support surface. In another aspect, a combined manipulation/welding arrangement is supported for controlled movement with a free end configured for engaging the workpiece to bias the workpiece against the support surface to manipulate the workpiece against the surface and to conduct an electrical current, while holding the workpiece, for welding to the support surface.
