Abstract
Owing to the superior properties of stainless steel it is pertinent to make use of it in various automotive aerospace nuclear chemical and cryogenic applications It is observed that a wide range of dissimilar materials can be easily integrated by solid phase bonding techniques such as friction welding and explosive bonding This study mainly focuses on friction welding of AISI 304 austenitic stainless steel The friction processed joints are evaluated for their integrity and quality aspects Friction welding of austenitic stainless steel was carried out using a KUKA friction welding machine Germany As the friction time increased the fully plastically deformed zone region I in the vicinity of the bond line becomes increased In contrast an increase in friction time will decrease the region region II where the grains are partly deformed and grown Tensile test results indicated that the joint strength is decreased with an increase of the friction time The detailed fractographic observation confirmed that the rupture occurred mostly at the joint zone and partly through the base material
