Effect of speed on tensile strength and hardness of friction welded joint

Abstract

Welding of dissimilar metals take place due to uneven heating in the outide and inside zones of materials.  This paper discusses, the Joining of two non-metals like copper, aluminium & brass  using friction welding method by varying the different speeds like 1800,1400,1120,960 rpm’s to analyse the hardness and strength of a material by conducting Brinell Hardness test hydraulic load test and also studied the effect of time on speed.
