A Review on Advancement in Friction welding Process

Abstract

Solid state joining techniques such as friction welding are used. This procedure is based on the idea
that metals can be welded together at high temperatures using friction between the metals to be
fused. The mechanisms of friction welding (FRW) and friction stir welding (FRSW) are compared and
contrasted in this short explanation of friction welding techniques (FSW). There is friction between
the two specimens in FRW, but in FSW, a revolving tool is used to fuse the material. A review of
current research reveals numerous advantages and disadvantages for each approach. Factors such
as rotation speed, welding speed, axial force, tool geometry, and flaws are examined in the study of
FSW joints. Welding FSW showed advantages when it came to adaptability, optimal process
parameters, and a wide range of dissimilar metals and alloys that could be joined.
