Evaluation Of Microstructure And Mechanical Properties Of Explosively Welded Aluminium Alloy And Low Carbon Steel Plates

Abstract

In the present paper joining of aluminium alloy-AA1100 and low carbon steel (LCS) plates has been carried out using explosive welding technique. Welding parameters were optimized in order to achieve uniform and good quality welds. Optical and scanning electron microscope (SEM) were employed to observe the morphology and microstructure at the interface boundary. Mechanical properties of weld joints have been evaluated by carrying out ram tensile and hardness test. After successful joining of plates, the bonding interface had laminar morphology free from major cracks. No delamination was observed at the interface of the clad plate when subjected to chisel test. The bonding strength of the weld joint was more than the strength of weaker material.
