Abstract
A welded joint between two metal members in which the weld must support a structural load. The abutting faces of the welded members have step portions formed therein, in which the step portions extend beyond the surface of the adjoining welded members. The outer step portion of one member extends beyond an inner step portion of the adjacent member, and a weld is applied on abutting faces of the members and the step portions. The welded joint of this invention is intended to be used for two adjacent rotor discs in a gas turbine engine. But, the weld arrangement of this invention can be used for welding two pipes together, or two adjacent plate members. The weld arrangement of this invention provides for reduced stress distribution along the weld line that acts to increase part life.
