Abstract:
The invention concerns a method for manufacturing a steel component (6, 11) comprising a first steel part (7) and a second steel part (8), the first (7) and second (8) steel part having a carbon content up to 1.5 weight percent, The method is comprising: Heating (1), at least partly, the first steel part (7), and at least partly, the second steel part (8), to above the alpha/gamma transformation temperature, and joining (2) the first steel part (7) and the second steel part (8) by welding, the welding taking place at a temperature above the alpha/gamma transformation temperature, and cooling (3) such that hardening effects are avoided. The invention further concerns weld seams (9), welded steel components (6, 11), and bearing components (11, 15, 20, 22, 26, 27, 31).
