摘要：
A method for producing pistons that can be used in internal combustion engines made from lightweight metal, with a combustion bowl assigned to one piston head, wherein a bowl rim is subjected to a melt treatment. In a first method step, the bowl rim is inductively heated. In a second method step, the material of the bowl rim, also to be referred to as the delimiting zone, is improved by means of a laser beam.
