The extruded AZ61A magnesium alloy plates of 6 mm thickness were butt welded using friction stir welding (FSW) process. The corrosion behavior of the welds was evaluated by conducting immersion test in NaCl solution at different pH value, immersion time and chloride ion concentrations. An empirical relationship was established incorporating pH value, immersion time and chloride ion concentratio...

In this paper experimentally, the friction-stir welding of the polypropylene sheets with 40% glass fiber has been investigated. Comparison to other welding methods, the strength of the joint is the most important feature in this process. Many parameters such as tool geometry, rotational speed, linear velocity, and tilt angle are very important as input parameters in this type of welding. Theref...

Friction stir welding (FSW) is a solid-state jointing technology, and has the advantages of high joint strength, low residual stress, small deformation after welding. During FSW, temperature directly influences quality weldment. A heat generation model FSW medium thickness aluminum alloy 2219 established considering friction generated at interface between tool workpiece plastic weldment materia...
