DEVICE FOR SEAM WELDING

摘要

FIELD: metallurgy. ^ SUBSTANCE: device consists of base (1) with poles (3) and pneumatic cylinders of short travel. Case (5) is hinged by brackets (6) and axes (7) and in its lower part has guides with vertical slots for connection with axes (4) of poles (3). Case (5) in its upper part is equipped with copper backing bar (9) in form of a set of butt-jointed plates for making a welding seam. Inside the case there are formed cavities for circulation of cooling liquid. ^ EFFECT: high quality of weld seam of panel of length over 2 m; improved conditions for its operation due to elimination of jams of rods of pneumatic cylinders. ^ 4 dwg
