Abstract
A method of forming a welded component by electron beam welding, and the resulting welded assembly. The method is particularly directed to the welding of a component whose subcomponents are formed of dissimilar metals, with the result that an electron beam used to weld the subcomponents is prone to being deflected away from the contact surface interface between the subcomponents and into one of the subcomponents as it passes through the interface. The method is also suitable for welding applications in which the interface between the subcomponents has an arcuate shape. The method involves magnetically steering the electron beam so that the beam is caused to follow the desired path through the interface.
