Volume 8 No.2 April-June 2019 pp 16-18
Friction Crush Welding (FCW) is a new technology of joining thin sheets in the field of friction welding, which is based on the relative motion of tool and work-piece. In friction crush welding, calculated flanged part of sheet is compressed into the specified gap between the two sheets, with the help of rotating tool. In this research paper, trapezoidal and spherical profile of rotating tool are designed and an experimental study is carried out between trapezoidal and spherical profile of tool to analyze its effect over the bond strength of weld, under a given set of input parameters like speed (RPM) and feed (mm/min). The results of experimentation revealed that under a given set of input parameters, trapezoidal profile of rotating tool gives maximum bond strength in terms of breaking load in comparison to spherical profile.
