in this paper, dissimilar resistance spot welding of aisi 1075 eutectoid steel to aisi 201 stainless steel is investigated experimentally. for this purpose, the experiments are designed using response surface methodology and based on four-factor, five-level central composite design. the effects of process parameters such as welding current, welding time, cooling time and electrode force are inv...

Computational Welding Mechanics, CWM, can not only be used for RSDP, Residual Stress and Distortion Prediction [1]. It can also be used for a broad range of applications such as remaining life time analyses of reactors, pressure vessels, boilers, furnaces, tubeand pipe systems. As well as the Manufacturing Engineering process of integrated metallic structures that is the engineering discipline ...

In this paper, a low cost, high performance and full PC-based sensor system for the pulsed gas metal arc welding (PGMAW) is described. It allows the visual online observation of all states of the welding process, including the material transition, and all welding situations without an additional lighting unit. Additionally, the synchronized measurement of the welding current and welding voltage...

Identification of significant process parameters using experiments needs to be carefully formulated as it can be a resource demanding process. Using appropriate statistical techniques such as the Taguchi method of factorial design of experiments, the number of necessary experiments can be reduced and the statistical significance of parameters can be safely identified. In the case of linear fric...

FSW is a solid phase welding, invented by W. Thomas and his colleagues at The Welding Institute (TWI), UK, in 1991. It is proven that FSW is completely user friendly, non hazardous and produces no effluents. From the advent of the modern Welding technology, most of all the techniques that were developed produced fumes and gases that were hazardous to the welders and the environment. Protective ...

Friction stir lap welding of 7B04 aluminum alloy was conducted in the present paper, and the effect of welding speed on the defect features and mechanical performance of lap joints was investigated. The results indicate that the hook defect at the advancing side (AS) can reduce the effective thickness of the top sheet, and the sheet thinning level is gradually lowered by increasing the welding ...
