Cladding of Cylindrical Parts with Dissimilar Steel Combinations Via Gas Metal Arc Welding
摘要
Cladding processes are applied to improve the physical and mechanical properties of existing parts or to provide them the desired additional properties. Welding methods, which are widely used in joining materials today, have also allowed the possibility of cladding. This study deals with the application of cladding on cylindrical parts using gas metal arc welding. Cladding processes were applied to cylindrical AISI 1010 and AISI 304L steel in different combinations with low alloy steel (ER70S-6) and stainless steel (316LSi) wires. The process was applied in a total of five different substrate–cladding material couples. The macrostructure analysis showed that the applied method can produce reasonable cylindrical cladding samples without macrodefects. Depending on the substrate–cladding material, the cladding dimensions varied, especially the differences in thermal properties between these affected the dimensional variation. The rapid melting, cooling, and solidification pattern of the cladding wire due to the welding process resulted in different microstructure order in the cladding region. This variation resulted in a change in the microhardness of the cladding and the regions close to the substrate. The study showed that the gas metal arc welding method can be used for successfully cladding cylindrical parts in different material combinations.
