Purpose: Purpose of this paper was to understand the structure and chemical composition changes of gas metal arc welded joints of wear resistant plate with constructional steel plate with possible application as replacing material for reservoirs and chute in cement industry. Based on the experiment results presented it is clear that welding of wear resistant plate with constructional steel is possible, but special attention is needed during the welding process of the root. Design/methodology/approach: Wear resistant plates can be used for elements working in intensive abrasion resistance conditions to obtain considerable material and economical savings based on the manufacturing costs reducing and decreasing turnaround time for replacing worn parts. During the welding process of two materials, when one is wear plate and the other is steel plate significant structure changes and mixing of alloying components in weld area are observed. Findings: Based on the experiment results presented it is clear that welding of wear resistant plate with constructional steel is possible, but special attention is needed during the welding process of the root, most of important changes during welding of wear resistant material are connected with melting, mixing and carbides passage into weld area, non uniform chemical composition of the welded joint creates different microstructures with different hardness. Practical implications: Welding of wear resistant plate with constructional steel is possible, but special attention is needed during the welding process of the root. Root weld must be free of cracks and possibly free of intermixing with wear resistant plate material. Applying welding parameters described in the paper is possible to achieve free of cracks root, presence of crack in face weld is not important in term of wear resistance abilities of chute. Originality/value: Development of new generation materials, which allow intensive use in machine parts with extended life-time is clear in demand especially when considering the economic aspects. Technological progress of new materials and new solutions for the future should be carefully and precisely analysed.
