The course content is designed to have systematic and comprehensive understanding on various aspects related with weldability of various metal systems of commercial importance. It is proposed to include weldability, factors affecting weldability of metals, weldability of plan carbon steel, alloy steel, and stainless steels. Presentations will be supported with case studies for effective communication of concepts and procedures. Case studies will be taken up regarding dis-continuities in metal systems like ferrous and non-ferrous metals.

Intended audience: UG and PG Student, Research Scholar & Practicing Engineers
