Abstract
An assembly of a crown wheel and a differential casing of a differential gear assembly is adapted to welding. The differential casing has a circular flange with an axially extending lip engaged in a circular groove of the crown wheel, which is further relieved at a radially outer side to give clearance for a high energy welding beam. An interface between the crown wheel and the circular flange is in one example a frusto-conical surface, which presents an oblique angle to the welding beam.
