The widespread application of thermoplastic polymers in different aspects of industries has motivated researchers and companies to improve and upgrade their forming, joining and assembling processes to overcome their limitations. One of the newest joining methods of thermoplastics is friction stir welding which is based on frictional heat generated through contact between a rotating tool and th...

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...

Purpose This study aims to enable robotic friction stir welding (FSW) in practice. The use of robots has hitherto been limited, because the large contact forces necessary for FSW. These are detrimental position accuracy robot. In this context, it is not sufficient rely on robot’s internal sensors positioning. paper describes and evaluates a new method overcoming issue.
