Sheet metal process - Free download as PDF File (.pdf) or view presentation slides online. Sheet metal processA novel process for butt welding of thin metal sheets was developed and named as surface friction welding (SFW), which utilizes friction heat and severe plastic deformation like friction stir welding (FSW). The joining mechanism of the SFW is based on not stirring by the pin tool but surface friction between tool shoulder and joining metals.
