Department: Mechanical Engineering
Author: Prof. Dheerendra Kumar Dwived
University: IIT Roorkee
Type: WebLink
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.
