Abstract

In the present work an attempt was made to investigate the weld ability of High density polyethylene (HDPE) sheets by a hybrid friction stir welding process called i-fsw (Induction Assisted Friction stir welding) where the friction stir tool during welding is heated by Induction and the temperature is precisely maintained through a temperature feedback control system. The mechanical behavior and weld micro structure of the joints were studied over a wide range of tool rotational speeds and tool pin temperatures. A narrow transition zone between the weld and base material without any defect ensures joints with a strength similar to the base material, better than previously reported results with the same material.
