Abstract: An assembly of crown wheel (12) and casing (11) of a differential gear assembly (10) is adapted to welding. The casing (11) has a circular flange (17) with an axially extending lip engaged in a circular groove (33) which is further relieved at the radially outer side to give clearance for a high energy welding beam (13). The interface between crown wheel (12) and flange (17) is preferably a frusto-conical surface (70, 65) which presents an oblique angle to said welding beam.
