WELDING EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a welding equipment which is capable of efficiently performing welding with high quality by automatic remote controlling. SOLUTION: The welding equipment which having TIG welding torches 11a and 11b for TIG welding a nozzle stub 8 penetrating a lower end plate (end plate section) 7 constituting a nuclear reactor vessel at narrow gaps 9 worked at the peripheral edges of the nozzle stub through-holes is constituted by mounting a welding equipment body 10 which is provided with two units of the TIG welding torches 11a and 11b around a swiveling shaft 18 and supports these torches in a manner as to make the multispindle movement inclusive of at least the swiveling shaft possible on traversing beams 3 supported in a lower cylinder 1 constituting the nuclear reactor vessel by means of a traversing truck 5 and a vertical moving truck 6.
