Basic Materials and Weldability

The weldability of any material can be classified into two categories namely, weldability for fabrication and weldability for service. While the weldability for service aspects have received considerable attention from research workers in India, the weldability for fabrication has been a neglected field. This paper reviews the above two aspects of weldability as applied to common fabrication materials. The available information has been critically analysed and areas where further research efforts should be directed are outlined.
