摘要：Advancements in welding have been rapid in
recent times and joining two similar and dissimilar metals in
solid state of metal is on high demand as revealed from the
literature studies. Friction Welding (FW) is one such advanced
technique of uniting two parent metals at solid state. The
fundamental advantage of the FW is that is more efficient in
joining the dissimilar materials as this method provides
outstanding weld seam with good mechanical and
metallurgical properties in comparison to other welding
methods. Unavailability of a FW set up in CCE is also another
source of inspiration that is addressed through this project
work. Selection of work holding parts, prime moving devices
and design of a suitable electronic controller pose a greater
challenge in making the FW set up. There is no reservation on
the geometry of work pieces (such as plates, pipes and rods)
that can be welded. However, in this work, round cylindrical
metallic solid rods of diameter ranging from 10 mm to 20 mm
are welded using FW set up. Similar and dissimilar base metals
(mild steel to mild steel, stainless steel to stainless steel, copper
to aluminium and copper to bronze) are welded with this
process. The FW on stainless steel and mild steel rods was
achieved at a rotational speed of in the range from 2100 rpm to
2400 rpm while the temperature of heat generated ranges
between 950oC to 1000oC. Finally, welded pieces are subject to
tensile testing on UTM in order to compare the results
obtained through FW with that of conventional or other
advanced welding methods so as to confirm the usefulness of
this set up. The testing results show good agreement in most of
the cases and in some cases, welding conditions to be improved
to achieve the full efficiency and comparable mechanical
property values.
