For resistance welding, an electrode assembly includes auxiliary nonconductive clamping means providing a resilient supporting surface flanking the electrode work face. For a spot-welding electrode the auxiliary clamping means may be a sleeve enclosing the electrode; for a seam-welding roller electrode it may be a pair of discs or rings, one on each side of the roller electrode. Its primary use is in overcoming difficulties experienced in the welding of soft heavy metals such as lead, for example.
