Title:
METHOD FOR PRODUCING A LARGE-DIMENSIONED COMPONENT FROM NODULAR GRAPHITE IRON
Document Type and Number:
WIPO Patent Application WO/2012/010512
Kind Code:
A3
Abstract:
The invention relates to a method for producing a component from nodular graphite iron, comprising the following steps: constructing the component (1) from nodular graphite iron in such a way that the component (1) is composed of a plurality of component parts (2, 3); placing the component parts (2, 3) against one another in pairs, wherein one of the partial joints (8) is formed by an edge (6) of an edge section (4) of the first component part (2) and an edge (7) of an edge section (5) of the second component part (3); applying buffer material (9, 10) to the edges (6, 7) by low-energy arc welding or friction welding or electron beam coating or thermal coating or induction coating; welding the edge sections (4, 5); wherein the buffer material (9, 10) is selected such that, during the welding of the edge sections (4, 5), a structural change in the nodular graphite iron material of the component parts (2, 3) is suppressed, wherein an addition material based on nickel, in particular, SG - NiTi4 or SG-NiCu30MnTi, is used to apply the buffer material (9, 10).
