Welding machine with row of workpiece clamps - esp for pairs of workpieces joined together by submerged arc welding burner to make electric contact clamps

On the machine bed is a row of clamps, which each consist of a stationary baseplate (I) below two clamping jaws. Each jaw is mounted on elbow levers, which are driven in pairs to clamp one pair of workpieces on each plate (I). Adjustable limit stops are provided for the levers. A long rail can be moved onto plate (I) to form a limit stop aligning pairs of workpieces before the latter are clamped. Above the row of clamps is a welding burner, which can be driven along the machine bed for the successive welding of pairs of workpieces. In an embodiment, a submerged arc burner is used. Used for automatic or semi-automatic mass prodn. welding.
