Abstract
A welding apparatus for welding hard segments to the circumference of a base of a saw blade. The blade base is clamped between two electrodes of a first electrode unit which can rotate. The segment is clamped by conductive fingers of a second electrode unit which is movable toward the first electrode unit. A power clamp presses together the conductive fingers together. The second electrode unit can rock to uniformly press the segment against the circumference of the blade base.
