Abstract

A method of electron beam welding comprising splitting the output of an electron beam welder into two components, a pre/post heat ring and a fusion spot by rastering between the pre/post heat ring and a fusion spot, applying the two outputs to a workpiece that is to be welded, traversing the two outputs along the desired weld path, and wherein the fusion spot lies within the pre/post heat ring and travels in tandem with and inside the pre/post heat ring. The pre/post heat ring may be annular. The fusion spot may be located at the centre of the pre/post heat ring. The output of the electron beam welder may comprise 1 to 100,000 discrete points. The beams may be deflected using the EB welder deflector coils. The time the electron beam spends on each discrete point may be identical.
