    • 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) which are placed against one another, forming partial joints (8), and are dimensioned and designed such that they can be cast from nodular graphite iron without critical flaws in the material; 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; placing the edge section (5) of the second component part (3) against the edge section (4) of the first component part (2) such that the buffer materials (9, 10) of the edges (6, 7) rest against one another; welding the edge sections (4, 5) such that the partial joint (8) formed by the edge sections (4, 5) is welded and thereby the first and the second component parts (2, 3) are attached to one another, whereby the first and second component parts (2, 3) at least partially form the component (1); 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.

    • A clad plate comprising an improved wear resistant cladding. The clad plate comprises a substrate plate (11) having a plurality of adjacent lines of continuous bead welding (12) deposited thereon via arc welding. The bead welding is deposited in a wave-like fashion to form a sinusoidal or herringbone pattern. The bead welding can be deposited to form a cladding comprising a single layer or a cladding comprising multiple layers. The wave pattern of the clad layer substantially improves wear resistance of the clad plate and reduces the problem of channel wear brought about by exposure to highly abrasive environments because the abrasive materials cannot be carried continuously within the interstices between the bead welding lines as the abrasive materials flow across the clad plate. The clad plate shows greatest wear resistance when used in a manner such that the abrasive materials being handled by the clad plate move across the cladding perpendicular to the direction of bead welding line deposition.
    • 包括改进的耐磨包层的复合板。 复合板包括具有通过电弧焊接沉积在其上的多个相邻的连续焊道焊接线(12)的基板(11)。 胎圈焊接以波浪形式沉积以形成正弦或人字形图案。 可以沉积珠焊,以形成包括单层或包含多层的包层的包层。 包覆层的波形显着改善了复合板的耐磨性,并且减少了由于暴露于高度磨蚀性环境而引起的通道磨损的问题,因为磨料不能在珠焊线之间的空隙内作为研磨材料 流过复合板。 复合板在以包覆板处理的研磨材料垂直于焊道焊接线沉积的方向穿过覆层的方式使用时,具有最大的耐磨性。
