Résumé

The purpose of this study is to study the effects of various process parameters (welding current, filler materials and groove design) of tungsten inert gas welding (TIG) on aspect ratio, hardness and impact strength of SS304L welded joint. Aspect ratios are obtained by taking the ratio of bead width and bead penetration. This bead dimensions can be measured by digital vernier calipers. Weld joint quality depends on the bead dimensions. Bead dimensions of the welded specimen is mainly dependent on welding current, so that, aspect ratio is our response parameter. Rockwell hardness test set up gives hardness at fusion zone, heat affected zone and base metal zone. Impact strength of a material is defined as the resistance offered by the material against the suddenly applied load. Impact test on the weld specimen is performed on the impact testing machine. Impact strength generally depends on the heat input. This SS304L material is generally used in industrial field such as steam power generation, automotive engineering, biomedical engineering and dairy industry, petrochemical engineering and chemical engineering. So, the above mentioned mechanical properties are required to be estimated. Hence in this study, the above parameters of TIG welding for hardness, impact strength and aspect ratio of SS304L welds were optimized by using Taguchi orthogonal array (OA) experimental design and other statistical tools such asanalysis of variance (ANOVA) techniques. Cite this ArticleBhavsar Arpita N, Patel Vikram A.Influence of Process Parameters of TIGWelding Process on MechanicalProperties of SS304L Welded Joint: AReview.
