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...

Friction Stir Welding (FSW) is a solid-state welding process, based on frictional and stirring phenomena, that offers many advantages with respect to the traditional welding methods. However, several parameters can affect the quality of the produced joints. In this work, an experimental approach has been used for studying and optimizing the FSW process, applied on 5754-H111 aluminum plates. In ...

in this paper, the deep drawing process of tailor welded blanks is simulated using the finite element modelling and verified using the experimental results available in the literature. then the effect of die and material properties on the welding line movement is investigated. it is seen that the most effective material parameters on weld line movement are different between sheet metal thicknes...

Industries involved in surfacing operations use various fusion welding especially arc welding processes. These operations demand high deposition rates but at low penetration values in the base metal. Conventional SAW, besides its high deposition characteristics, employs high values of welding current and is not many times favoured for surfacing due to high degree of dilution of surfacing alloys...

Gas Metal Arc Welding (GMAW) processes is an important joining process widely used in metal fabrication industries. This paper addresses modeling and optimization of this technique using a set of experimental data and regression analysis. The set of experimental data has been used to assess the influence of GMAW process parameters in weld bead geometry. The process variables considered here inc...

Micro-friction stir spot welding (µFSSW) is one type of that suitable for joining lightweight materials. One the challenges in materials with µFSSW material easily perforated, or join not strong enough, so it necessary to select right parameters. In this article discusses about investigates micro-Friction Stir Spot Welding parameters on weld geometry, mechanical properties, and metallography di...

Welding is an important process used in the iron based industries. About two percent of the working population is engaged in some type of welding. The procedure of welding is simple but its health implications are complex. Welding generates enormous amounts of gases and metal fumes. Depending on the substrate and welding type, the composition of resultant gases and fumes changes. Therefore, wel...
