چکیده مقاله
Surface welds are deposited on the surface of the parts in order to achieve the desired properties or dimensions One of the features of surface operations with the help ofwelding is to achieve properties such as corrosion resistance,Erosion resistance, reduction of friction coefficient, etc at the level of base materials at a cheaper price Inthis research, ST37 steel coating was performed by two electric arc and argon welding processes, using HS60V electrode and its powder Coating by arc welding in the centralgroove of ST37 steel piece and coating by argon welding, once by replacing HS60V electrode powder in the central groove on the base metal and once by applying thepowder coating of this electrode in the form of wafer on the base metal The mechanical properties of the samples were investigated using Vickers hardness and microstructure and the microstructure of the samples was studied using a light microscope The results show that the microstructure of the coating by powder coating method in the form of wafer shaped and argon welding, and the coating by arc welding method, both in the welding area have Wiedmann Statten ferrite and acicular ferrite The hardness results in these two samples are 800 Vickers and 780 Vickers, respectively
