Abstract
A method for manufacturing a rim is provided to overcome the problem that the strength of the rim as manufactured by the conventional manufacturing method reduces due to the annealing of the welding operation. The method includes processing a first material with a cold stamping process to form a disc embryo, with the first material being made of steel; processing a second material with a cold rolling process to form a rim embryo, with the second material being made of steel; coupling the disc embryo and the rim embryo with each other by a welding approach to form a semi-processed rim; and processing the semi-processed rim with a hot stamping process to form the rim.
