Abstract
Friction welding is a solid state welding technique with high automation and good quality.it
has been broadly applied in various industries especially in aerospace and automobile
industries. Because of high level of automation and less process parameters, the inertial
friction is common in many fields. There are many merits which are associated with the use
of friction welding in production such as, it is fast method of welding as compared to other
welding techniques. Even though there are many benefits which are associated with it, there
are also some drawbacks such as, is mainly used in round bars which have the same cross
section.

1.0 Introduction

FRICTION WELDING 4
Friction welding is defined as Solid state or a simply forge whereby the welding process
occurs between two mating surfaces of metals through the application of friction between
them. The welding technique has been adopted by well-known international companies in in
America and Europe such as American Manufacturing Foundry and Rockwell international to
manufacture their machines.
Friction welding is considered to be very essential in the production industry, by adopting
this welding method the high overhead costs which the companies will undergo to have this
technique in place will be balanced with the high production rates and lower labour
requirements.
The friction welding technique has many dimensional and hardware which are easily
adjustable making it to be very significant in the production of very small parts and
components. There are many industrial applications where friction welding can be applied
such as the machine and spare part production.
2.0 Background.
The process of friction welding was first discovered in the late 1920s, however during that
time there was very little data which was recorded about its use. A detailed discussion about
friction welding was recorded in the USSR in the early 1960s, but that time it was described
as ‘very doubtful, as a production technique due to the challenges in generating reciprocating
linear motion. The fist well-structured industrial research into friction welding took place in
the 1980s at TWI, UK, while the first ever research academic to be to be recorded took place
at Ohio State University, and the University Of Bristol, UK.
3.0 working Principle
The friction welding technique works on the basic principle of friction. In the process of
welding, friction is used to create heat at the interfaces surfaces (Anderson, 2016). The heat is
