A stud bolt welding jig which produces a standardized product capable of always connecting stud bolts to accurate positions on an outer surface of a stainless steel corner and improves productivity by connecting the stud bolts to the accurate positions even when doing a large amount of work within a limited time is provided. In a jig that is fixed to weld stud bolts to an outer surface of a stainless steel corner(1) connected to a corner side within a cargo containment of an LNG vessel, a jig(100) for welding the stud bolts comprises: a base frame member(10) comprising placement parts formed to place the stainless steel corner on upper portions thereof; and a guide frame member(20) which is placed between the two vanes by having an area corresponding to a distance between two vanes formed on the outer surface of the stainless steel corner, and comprises position fixing holes(21a) with the same positions and number as the stud bolts connected to the outer surface of the stainless steel corner, wherein the stud bolts are welded to the outer surface of the stainless steel corner by a welding gun after inserting the stud bolts into the position fixing holes.
