Butt TIG welding was performed for 316 stainless steel (SS) by using different pre welding stand-off distances with fixing the other parameters (thickness of welded plates, voltage, current, groove shape, and scanning speed). The influence of the stand-off distance parameter was examined by using tensile test, hardness test in the three different regions (base metal, heat effected zone, and.
This paper presents an experimental design approach to process parameter optimization for gas metal arc welding of austenitic stainless steels. Face-centered central composite design of experiments, based on response surface methodology (RSM) has been adopted. The selected input parameters are welding current, gas flow rate and travel speed.
Therefore, this present paper reviews past research findings on GTA welding of ASS and FSS. Results of the findings have confirmed that, depending on the amount of heat input, which can be controlled by welding parameters (welding speed, voltage and current), welded joints particularly, heat affected zones (HAZs) of both grades of steels can undergo mechanical failure and can be susceptible to.
An Analytical Study of Dissimilar Materials Joint Using Friction Welding and It’s Application. Abstract- In this research paper the effect of friction welding parameters such as rotational speed, friction time, forging pressure and friction pressure on tensile strength of a joint between SS316 and EN8 is experimentally investigated. A partial factorial design of experiment based on.
Welded joints are made by the various processes like TIG, MIG, spot resistance welding, arc welding process etc. For the present research study, MIG welding process is selected for analysis the welded joints. Three process parameters are selected for this study which is feed rate, gas flow rate and gap among pieces. The design of experiment.
The MIG welding parameters are the most important factors affecting the quality, productivity and cost of welding. This paper presents the influence of welding parameters like welding current, welding voltage, Gas flow rate, wire feed rate, etc. on weld strength, weld pool geometry of Medium Carbon Steel material during welding. By using DOE method, the parameters can be optimize and having.
This paper reports an experimental study and FEA simulation of fiber laser butt welding on 1 mm thick A304 stainless steel. A new heat source model (cylindrical and cylindrical) is established to match the actual weld profile using Marc and Fortran software. Four bead geometry parameters (penetration depth, bead width, waist width, and depth of the waist) are used to compare between the.
In this review paper it was tried to consider different research papers containing the research and analysis made on input output parameters of submerged arc welding process. This paper also focused on analysis of some research papers containing heat input rate, cooling rate of weld, micro structure of weld and heat affected zone and their effect on the performance of the joint.
