Induction assisted friction stir welding (i-fsw): A Novel Hybrid process for joining of Thermoplastics.
Masters thesis, Indian Institute of Technology Hyderabad.
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.
