摘要：
The invention relates to a method for producing pistons (1) that can be used in internal combustion engines from lightweight metal, with a combustion bowl (3) assigned to one piston head (2), wherein a bowl rim (4) is subjected to a melt treatment. For this purpose, in a first method step the bowl rim (4) is inductively heated. In a second method step, the material of the bowl rim (4), also to be referred to as the delimiting zone, is improved by means of a laser beam.
