Course Name: Joining Technologies for metals

Course abstract

It is proposed to include following joining technologies of commercial importance under different groups of processes A) Fundamentals of Metal Joining Technologies: mechanisms for obtaining metallic continuity: fusion, deformation, diffusion, chemical interactions B) Fusion based processes: principle of fusion welding processes, oxy-fuel has welding, common arc welding processes, laser beam welding, spot welding processes, newer variants of fusion welding processes C) Solid-liquid joining processes: brazing and soldering, braze welding, cold metal transfer welding, D) Solid state joining processes: diffusion bonding, ultrasonic welding and explosive welding and E) Adhesive joining: design, procedure, and applications F) Metallurgical Aspects of Welding: weld thermal cycle, solidification of weld metal, weldability of carbon steel, alloys steel, stainless steels, and aluminium alloys, Fe-C, CCT and schaffler diagram for understanding the metallurgical transformation in weld and heat affected zone., basics of residual stresses G) Common issues related with joining technologies their causes and remedies: hardening and softening of heat affected zone, porosity, cracking.
