Effect of welding parameters on pitting corrosion rate of pulsed current micro plasma arc welded AISI 304L sheets in 1N HCl
Austenitic stainless steel sheets have gained 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 industries. In the case of single pass welding of thinner sections of this alloy, Pulsed Current Micro Plasma Arc Welding (PCMPAW) has been found bene...
متن کاملInvestigating the Effect of Current Type (Direct and Pulsed) on Microstructure and Mechanical Properties of Hastelloy B-2 Superalloy Welded Joint by GTAW Process
In this research, Gas tungsten arc welding (GTAW) on Hastelloy B-2 Superalloy was used to investigate the effect of current type on microstructure and mechanical properties of welded zone. The welding process was performed using two direct and pulsed current and with Hastelloy X filler metal. Optical Microscope (OM) and Scanning Electron Microscope (SEM) were used to investigate the microstruct...

متن کاملapplication of grey relational analysis for optimizing weld pool geometry parameters of pulsed current micro plasma arc welded aisi 304l stainless steel sheets
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...
متن کاملReliability-Based Robust Multi-Objective Optimization of Friction Stir Welding Lap Joint AA1100 Plates
The current paper presents a robust optimum design of friction stir welding (FSW) lap joint AA1100 aluminum alloy sheets using Monte Carlo simulation, NSGA-II and neural network. First, to find the relation between the inputs and outputs a perceptron neural network model was obtained. In this way, results of thirty friction stir welding tests are used for training and testing the neural network...
