An arrangement is provided including an electrode extending to an electrode tip for contacting a workpiece. A welding configuration of the electrode tip is established by exposing the electrode tip to a selected welding environment for use in forming a weld having a target set of weld parameters. An electrode passage is defined in a biasing force arrangement supporting at least a portion of the length of an elongated, flexible electrode and to limit lateral movement sufficient to transfer at least a portion of a resilient force to the electrode tip so that the tip resiliently contacts the weld region. The electrode passage limits induced lateral flexing to an extent which transfers an amount of the resilient force to the first end portion of the electrode that is sufficient to provide for formation of a weld between the support arrangement and the workpiece.

A drug delivery system can include a cylindrical structure extending in a longitudinal direction and formed from a substrate of an electrically conductive material.

Spot welding electrodes with generally dome shaped welding faces are provided with surface features for welding both aluminum alloy sheet assemblies and steel sheet assemblies. A raised circular plateau is formed on the central axis of the dome and, in one embodiment, a suitable number of round bumps are formed in concentric spacing from adjacent the circumference of the plateau toward the circular edge of the welding face. For welding steel workpieces the plateau mainly serves as the engaging feature of the electrode.
