The present invention at least one and a piston body 11 having a piston skirt (15), at least one piston head 19, the annular with a top land 21 and the ring groove of the ring-shaped is formed in the ring zone 22 as including the piston ring member 12 has, and to a method for producing a piston main body 11 and the piston ring member for an internal combustion engine piston 10 for 12 to form a closed cooling channel (23) of the ring-shaped, the method is characterized by the following process steps: (a) the outer joint surface (29, 129, 229), the inner joint surfaces (31, 131, 231) with two joining surfaces (29, 31; 129, 131 ; 229, 231) for providing a bangagongpum (11 ', 111', 211 ') of the piston body 11 with the annular lower cooling channel section (23a), (b) the outer joint surface (32, 132 between the , 232), the inner joint surfaces (33, 133, 233) with two joining surfaces (32, 33; 132, 133; 232, 233), the piston ring member having an upper cooling channel section (23b) of the annular between the (12 ) bangagongpum (1 2 providing a ', 112', 212 '), (c) the cooling channel section (23a; 23b) extended portion (34a, 34b of the annular extending; 134b; the 234a, 234b) face the at least one joint forming a; (29, 129, 229, 31, 131, 231 32, 132, 232, 33, 133, 233), (d) the joint surfaces of the bangagongpum (29, 129, 229, 31, 131, 231 ; 32, 132, 232, 33, 133, 233), 112 bangagongpum (11 ', 111', 211 'bangagongpum (12) and the piston ring member 12' of the piston body 11 by friction welding through the ', 212'), the piston bangagongpum (10 ', 110') step, (e) bangagongpum piston (10 ', 110') for post-processing to the piston 10 and / or the finish processing step of combining a. The invention also relates to such a piston.
