A process for shielded metal arc welding of steel body made from dissimilar steel composition, particularly dissimilar medium carbon steel compositions. The process comprises heat treating the steel bodies in order to bring down the hardness of the steel bodies to a range of 250 to 400 BHM (Brinell Hardness Number) comprising one or several stages of heating and/or subsequent cooling of the steel bodies, preparing the weld joint comprising providing a suitable groove between the joining faces of the steel bodies, shielded metal arc welding providing root run and first layer cladding and at least one stage of build up by electrode. The process of invention is particularly useful for joining two broken steel parts of a critical machine component made from dissimilar steel compositions and eliminates the requirement of manufacturing a new component to replace the broken steel part
