Study of Friction Welding on Conventionel Lathes Machine

Friction welding process has been extensively used in the manufacturing industry
whereby it's used in the aerospace industry to join two different materials together to
create a good joint while retaining the parent material properties after welding. The
main objectives that was hoped to be achieved in this research was whether the two
pieces of metal can be welded together on the conventional lathes machine and if it
could be done what was the rotational speed value (RPM).
Due to the high cost of purchasing a friction welding machine, it was decided to
attempt to create the weld joint using conventional lathes machine. Various sources of
journals gave different values of good RPM rates but however this could not be taken
lightly as it depended on the material that was being chosen.
The scope that was taken was the varying rotational s@ which was E55RPM,
I325RPM and 2000RPM. The material of choice was AA 6063G5).
Research was conducted throughout the after the project was undertaken by the
author. A mini experiment was carried in FYP I term and morc tests werc conducrted
during the concurring semester. Micro - hardness and microstnrcturp were the two
choice of testing that was to be carried out.
