Process parameter optimization of gas metal arc welding on IS:2062 mild steel using response surface methodology
TL;DR: In this paper, the effect of various process parameters has been studied on welding of IS:2062 mild steel plate using gas metal arc welding process with a copper coated mild steel wire of 0.8mm diameter.
Journal ArticleDOI
A decision support system for the selection of an additive manufacturing process using a new hybrid MCDM technique
TL;DR: A novel hybrid Multi-Criteria Decision Making (MCDM) technique has been proposed to select an appropriate AM process from available AM processes and the results suggested that the Material Jetting (MJ) process produces dimensionally accurate and quality parts among available alternatives AM processes.
Journal ArticleDOI
Measurement and Mitigation of Residual Stress in Wire-Arc Additive Manufacturing: A Review of Macro-Scale Continuum Modelling Approach
TL;DR: This study focuses on the critical review of multi-physics continuum modelling of WAAM at a macro-scale level and reviews the simulation results discussed as thermal fields, residual stress and distortion, and experimental validation to provide a critique of real-life experiments.
Journal ArticleDOI
Multi-physics continuum modelling approaches for metal powder additive manufacturing: a review
Shekhar Srivastava,Rajiv Kumar Garg,Vishal S. Sharma,Noe Alba-Baena,Anish Sachdeva,Ramesh Chand,Sehijpal Singh +6 more
TL;DR: In this paper, the authors present a systematic approach in the literature survey related to metal additive manufacturing (AM) processes and its multi-physics continuum modelling approach for its better understanding.
Journal ArticleDOI
A multi-objective optimisation of TIG welding parameters using response surface methodology
TL;DR: In this article, the effect of different variables such as gas flow rate, travel speed and current for the welding of mild steel (IS: 2062) with TIG welding was examined.
