In this experimental work tensile and hardness tests of weldments have been carried out on an aluminium (H-30) and mild steel (AISI-1040) by Rotary Friction welding process on medium duty lathe machine at different spindle speeds. The temperatures, time taken for welding, tensile test and hardness test of weldments were evaluated and compared at different spindle speeds of two different diameter materials (10mm, 12mm of aluminium(H- 30) and 10mm, 12mm of mild steel(AISI-1040)). The experimental results pertaining to different welding parameters for the above materials using Rotary Friction welding are discussed and compared. . Investigations are carried on mild steel (AISI 1040) and aluminium (H-30), both as similar and dissimilar combinations. The results indicate that aluminum and AISI 1040 steel can be joined by friction welding.
