FIELD: process engineering.
SUBSTANCE: invention may be used in strip welding at specialised machines incorporated with high-efficiency continuous metallurgical units, for example, tube welding and profile-iron bending stands, and pickling lines. Common carriage carried guillotine shears secured thereto with top moving support and bottom fixed support, steadier of strips to be welded, welding torch and copper strap arranged there under and provided with key-type strip end clamps, and carriage drive. Hydraulic cylinder with rod is fixed vertically ahead of carriage. Rod free end is provided with roller mounted in supports to turn and to get in contact with welded strip front end to act thereon from below to displace said strip and provided for gap between strips ends. Hydraulic cylinder rod is connected with cylinder limit switch.
EFFECT: simplified design and servicing, higher reliability.
