An Investigation on Effect of Welding Current Mode on Weld Quality Characteristics of Microplasma Arc Welding of Inconel 625 Sheets
Abstract: Nickel alloys have gathered wide acceptance in the fabrication of components, which require high temperature resistance and corrosion resistance, such as metal bellows used in expansion joints in aircraft, aerospace and petroleum industry. In case of single-pass welding of thinner sections of this alloy, pulsed current microplasma arc welding was found beneficial due to its advantages over the conventional continuous current process. The paper focuses on studying the effect of …

Multi Objective Optimization of Weld Bead Geometry Parameters of Pulsed Current Micro Plasma Arc Welded Inconel 625 Using Enhanced Non-dominated Sorting Genetic Algorithm
Abstract: Pulsed Current Plasma Arc Welding (PCPAW) is one of the most widely used welding processes in sheet metal manufacturing industry. In any fusion arc welding process, the weld bead geometry plays an important role in determining the mechanical properties of the weld and hence, quality of the weld. Moreover, the geometry of weld bead involves several simultaneously multiple quality characteristics such as front width, back width, front height and back …

Hot Corrosion Behaviour of Sol-Gel Alumina Coated IN625 Alloy in Alkali Metal Chlorides and Sulphates Salt Deposit Systems
Abstract: Sol-gel derived alumina coating was applied on Inconel 625 alloy using dip coating technique and their hot corrosion studies were carried out in LiCl-NaCl and Na2SO4-K2SO4 salt deposits system at 650 °C and 850 °C respectively. Oxidation kinetics measurement indicated the occurrence of an order of magnitude lower oxidation rate and around 15–20 % higher activation energy for the coated substrate as compared to uncoated one. EDS analysis of the …
