In the automotive industry, a barrier to widespread implementation of friction stir welding (FSW) for aluminum joining is the perceived need for high cost, custom capital machinery. The reason for this perception is that the FSW process requires relatively large forces that commonly used automation machinery (e.g. an industrial robot) has difficulty producing. Further complicating the issue, is...

Aluminium alloy 6082-T6 plays a vital role in the fabrication of lightweight structures, especially for manufacturing artillery, defense vehicles, and aircraft. is well-known structural having high strength-to-weight ratio favorable corrosion resistance properties extreme environments. In this study, three friction stir welding (FSW) process parameters (spindle speed, weld shoulder penetration)...

The basic aim of present study is to examine the effect of main friction stir welding (FSW) parameters on the quality of AA 6063 plate welds. Welding of AA6063 was carried out by a vertical milling machine, using different tools with a stationary shoulder and during the welding no external heating system was used. Different welding parameters studied were the tool rotational speed which varied ...

Friction stir welding (FSW) is a solution to overcome the problems of AA 6061 welding. When initial temperature T0 material increased during FSW process while parameters are kept constant then parameter value can be lowered. was varied by Troom temperature, 50 0C, 75 100 0C and 125 0C. The weld joint design form square butt joint. By using this approach higher T0, with being constant, produce p...

Abstract In this work, electron backscattered diffraction (EBSD) was used to examine the evolution of grain structure during friction stir welding aluminum alloy 6061-T6. entire FSW range studied, microstructure found be governed by continuous recrystallization. An increase in temperature resulted only microstructural coarsening.

A simulation model was developed for the monitoring, controlling and optimization of the Friction Stir Welding (FSW) process. This approach, using the FSW technique, allows identifying the correlation between the process parameters (input variable) and the mechanical properties (output responses) of the welded AA5754 H111 aluminum plates. The optimization of technological parameters is a basic ...

In this research, St37 and 316L steel sheets were welded using friction stir welding (FSW) process and effective parameters such as the rotational speed, linear speed of the tool, pin diameter, and their appropriate values were studied. The microstructure, hardness, and strength of the different welding regions were investigated. It was observed that in the stir zone (SZ), a mechanical operatio...
