Abstract
The study examined the impact of different operating conditions of 2219 aluminium (Al) sheets and 304 stainless steel FSW. Recently, the FSW procedure has been utilised to fastening various materials as it was able for conventional fusion welding techniques to remove local casting errors. The microstructure and mechanical characteristics of the weld nugget depend primarily on several FSW parameters such as rotation of the instrument, feeding speed, offset and pin profile. The current paper examines and discusses the effects of instrument speed, feed rate, offset and the cleaning process for tensile behaviour. As demonstrated by the decrease in velocity from 710 to 500 rpm and the increase in feed rate from 40 to 80 mm/min, the joint was improved. Furthermore, by raising offset to 1.5 mm, the defect in the twisted area was reduced. The use of the ringing method also successfully enhanced the extension and tensile strength by 100% and 9%.
