Fusion Welding Processes and Methodologies

December 16 - December 20


The modern material assemblies require the combined use of metals for a given commercial application. Welding technologies are of critical importance for the construction of virtually all components of the assemblies. This course aims to elaborate the physical principles of arc, plasma, laser, resistance spot and electron beam welding processes. This includes, physical properties of molten weld pool, fluid and magneto fluid dynamics of weld pool, physics of electric arc-plasma, engineering the arc-plasma for welding, metal transfer and mass flow in the weld pool, laser/electron beam – material interactions, pressure and force balance in keyhole mode power beam welding, fundamentals of heat generation by Joule heating and process principles and overview on types of resistance welding processes. This course also aims to provide details about the advances that are made in mathematical modelling the physical phenomena that governs the heat generation and conduction during welding. Course participants will learn these topics through lectures, case studies and assignments to stimulate research motivation of

Course Content:

  • Introduction to the physics of arc
  • Introduction to arc welding processes
  • Introduction to laser and electron beam welding processes 
  • Heat transfer and metal transport in arc welding

About IIT Madras:

Indian Institute of Technology Madras is a public engineering institute located in Chennai, Tamil Nadu. As one of the Indian Institutes of Technology (IITs), it is recognised as an Institute of National Importance.Founded in 1959 with technical and financial assistance from the former government of West Germany, it was the third IIT that was established by the Government of India. IIT Madras has been ranked as the top engineering institute in India for four years in a row (2016-2019) by the National Institutional Ranking Framework of the Ministry of Human Resource Development.

IIT Madras is a residential institute that occupies a 2.5 km² (617 acre) campus that was formerly part of the adjoining Guindy National Park. The institute has nearly 550 faculty, 8,000 students and 1,250 administrative and supporting staff. Growing ever since it obtained its charter from the Indian Parliament in 1961, much of the campus is a protected forest, carved out of the Guindy National Park, home to large numbers of chital (spotted deer), black buck, bonnet macaque, and other rare wildlife. A natural lake, deepened in 1988 and 2003, drains most of its rainwater.
