Webinar: Dissimilar metal welding – Practical aspects


Organizer: In coloboration with Nickel Institute
Venue: Online - Zoom
Speaker: Dr. Krishnan Sivaraman, IWE
Date: 25 Aug 2023
Time: 06:30pm - 08:30pm
Registration Close Date: 23 Aug 2023



Dissimilar metal welding refers to the process of connecting materials with different alloys through welding. The filler material and both base metals need to be evaluated before choosing the best way to connect the metals. While fusion welding is a popular method, it does not work well for some combinations of metals. Reportedly, there are three main challenges with welding dissimilar metals; Different thermal expansion coefficients, Different metallurgy, and Potential for galvanic corrosion.

There is no simple, standardised approach when it comes to welding dissimilar metals. As such, one needs to analyse the situation before selecting a suitable methodology to join dissimilar metals. The webinar will focus more on a broader classification of the most used welding processes and welding techniques for some of the common dissimilar material combinations, critical factors to be considered and the practical aspects to be followed for achieving a satisfactory weld, and practical difficulties arising from the physical and chemical properties of dissimilar materials to be joined.


Dr Krishnan Sivaraman

Dr Krishnan Sivaraman is a Graduate in Mechanical Engineering, a Postgraduate in Metallurgy and a PhD in welding from one of India’s most prestigious institutes, IIT-Bombay.
Dr Krishnan has got close to 2 decades of experience in Welding, Metallurgy and Quality with Larsen & Toubro’s Heavy Engineering Division, one of the world leaders in the manufacturing of Pressure Vessels and Heat Exchangers.
He is also an International Welding Engineer (IWE) and is presently working with FCRIT Mumbai as an Associate Professor in the Mechanical Eng dept.  He supports many companies as a welding expert in India and is presently the Vice Chairman of the Indian Institute of Welding, Mumbai branch.  He has won many awards at the National level for his contributions to the welding field and has also presented many papers in Journals, conferences and seminars both at the National and International levels.
