ABSTRACT:
Disclosed is an electric welding method and apparatus using resilient means such as springs for supporting a work to be welded. The work can be set at a desired level at which required welding is to be effected, by yieldingly compressing the springs with an upper electrode on the work until the work has been lowered to the desired level. If the work is thick or stiff, the work can be lowered simply by pushing down the work with the upper electrode against the resilient force of the springs. If the work is thin or easy to bend or deform, the work must be lowered by pulling down the work table and the work together with the aid of an appropriate pull-down piston-and-cylinder. Exact positioning of the work and satisfactory welding are assured despite the simple positioning device.
