MULTI-AXIS WELDING MACHINE FOR CLADDING THE CURVED NOZZLE SURFACE OF A NUCLEAR STEAM GENERATOR

摘要

PURPOSE: A multi-axis welding device for cladding curved nozzle surface of nuclear steam generator is provided to improve the quality of welding by evenly welding the nozzle curved part of a steam generator. CONSTITUTION: A multi-axis welding device for cladding curved nozzle surface of nuclear steam generator comprises a base(10), a center pole(20), an arm(30), a support stand(40), a main movable part(50), an angle movable part(60), a torch part(70), a torch rotating part(80), and a torch movable part(90). The center pole is installed on the upper side of the base. The support stand is connected to one end of a horizontal stand. The main movable part transfers arm to the up down left right and rotates the center pole. The support stand is transfer angle movable part. The torch par performs a welding process.
