PIPE WELDING INSTALLATION Russian patent published in 1995 - IPC

Abstract RU 2034689 C1

FIELD: welding equipment. SUBSTANCE: installation has argon feeding device installed on roller table and made in form of rod with mechanism providing for its moving into space of pipe under welding for local blowing of welding zone through holes in rods communicating with argon supply line when rod is in operating position. Rod guide is hinge-mounted by means of levers on roller table and gets disconnected from the latter to receive and deliver pipes. Outlet roller table has truck with weld X-ray testing chamber installed for reversing along rails between driving and tension sprockets of chain. Rollers fitted on chain links form roller conveyor on chain whose ends are secured on truck. Testing is carried out in process of welding. Workpiece is moved along chain rollers. Design of control device incorporating program according to algorithm and coupling of device with mechanisms and transducers of installation provide automatic operation of installation. EFFECT: increased labour productivity, reduced consumption of shielding gas, enhanced quality of articles. 3 cl, 6 dwg
