摘要
The invention relates to a wheel rim made from a light alloy, such as an aluminium-based alloy, comprising a front face (10) and a tyre tread (20) which are welded together. The inventive method of producing the wheel rim (J) comprises the following steps: moulding of the front face (10) with a light alloy; provision of a weldable alloy strip with structural hardening; curving of said strip to produce a generally cylindrical shape; welding of the ends in relation to the curved strip with fusion of the strip material; forming of the strip by necking and/or spinning in order to form the tyre tread (20); and welding of the front face and the tyre tread to one another.
