Abstract: A joint unit includes a first metal pipe, a second metal pipe, and a joint portion (a region including a joint interface at which the end faces of the first and second metal pipes are joined to each other. At the joint portion, an outer circumferential bead portion protruding toward the outer circumference side and an inner circumferential bead portion protruding toward the inner circumference side are formed. The difference between the width of the outer circumferential bead portion (the width L1 of a grinding portion and the width L2 of the inner circumferential bead portion in a direction from the first metal pipe toward the second metal pipe is equal to or smaller than 40% with respect to the average value of the width L1 of the outer circumferential bead portion and the width L2 of the inner circumferential bead portion.

Abstract: A method of controlling a weld penetration profile on a workpiece (306) having an outer region and an inner region is described. The method comprises the step of applying energy to the outer region of the workpiece with a welder (302) to produce a weld pool (304). The method also comprises the steps of penetrating the workpiece (306) such that the weld pool (304) spans between the outer region and inner region, and also applying a shielding gas to the inner region at a pressure that provides a force that limits weld penetration. A corresponding apparatus is also defined.

Abstract: A first tubular, inner radial annular seam is produced to weld together two hollow cylinders by narrow-gap tungsten inert gas arc welding. Narrow-gap metal gas-shielded arc welding is used to create another tubular, outer radial annular seam to further weld together both hollow cylinders. In this manner, the rotational axis of the rotor shaft remains vertically aligned throughout the entire production method of welding together the shaft parts. In this manner, the required production time can be advantageously reduced and the use of welding filler can be effectively decreased.
