A weldment of a welding construction has a first member formed with a curved face, and a second member welded to the curved face of the first member. The second member has an inner conical face overlying the curved face of the first member and extending to a first end of the second member, and an oblique face extending toward the first end of the second member so that a distance between the oblique face and the inner conical face becomes smaller gradually toward the first end of the second member.
