EFFECT OF TIG HARDFACING PROCESS PARAMETERS ON THE STRUCTURAL CHARACTERISTICS OF SHUT-OFF VALVE COMPONENTS

The study presents an experimental investigation of the influence of GTAW/TIG cladding process parameters on the formation of microstructure and the dilution coefficient of the deposited layer on valve seats made of low-carbon alloy steel. The cladding was performed using 6M filler wire while varying the welding curren...

Surface Layer Formation of a 12KH18N10T Stainless Steel Toothed Base During Wire Electrical Discharge Machining

Wire Electrical Discharge Machining (WEDM) is an effective manufacturing process for producing complex-shaped components from difficult-to-machine materials. However, the thermal effect of electrical discharges alters the structure and condition of the surface layer. The aim of this study was to investigate the surface...
