摘要：
A method for producing a part from ductile iron, including the steps of designing the part in such a way that the part is composed of a plurality of part components, producing the part components from ductile iron, providing the part components in pairs, depositing buffer material onto the rim edge of the first part component and onto the rim edge of the second part component by means of deposition welding, laying the second part component with the rim section thereof on the rim section of the first part component so that the rim edges lie against each other with the buffer materials thereof, and welding the rim sections, wherein the buffer material is selected in such a way that a structure change in the ductile iron material of the part components is prevented when the rim sections are welded.
