Indian railways are today one of the largest users of welding consumables in the country, through welding as a fabrication tool was recognised only in the fifties with the setting up of the production units e.g. Chittaranjan Locomotive works, Integral Coach Factory, Madras and Diesel Locomotive Works, Varanasi under foreign collaborations.

Solid phase bonding is undoubtedly the first welding process to be used by man. The general phenomenon of this process is quite similar to the primitive method of forge welding and also to the Electric Resistance Butt Welding process. The Term "Pressure Welding" is often used as a synonym for solid phase bonding since almost all the solid state processes require pressure. The source of heating may be either gas mixture, electricity or open hearth fire.- A Retrospect

Twenty second day of April,1966 is a red letter day for all the lovers of Welding technology and its allied subjects in India, as on this day, our Indian Institute of Welding was incorporated as a limited Company under the Company Act, 1956.
There was no National Institute of Welding in India then to foster the technical development of welding. It was therefore essential that such a Technical Association was formed, at the earliest opportunity so that the development of welding could be guided in the proper channel and India can take its rightful part in National as well as International activities in the field of welding.

More than 15000 bridges of different lengths span the rivers, over the Indian Railways. About 350 important bridges are over 305 M in length. The girders of all these bridges are of rivetted design though there are quite a few bridges viz. Rajendra Bridge at Mokamah, Jagjivan Ram Bridge near Sonepur, Second Godavary Bridge at Rajamundry, Third Krishna Bridge at Vijaywada, Brahmaputra Bridge at Gauhati etc.

During service, the hammering action of the wheels when traffic is passing over the joints causes a protrusion to be formed at the landing rail due to cold flow. When the rails are butting against each other, there is likelihood of considerable compressive forces acting on the top portions of the rail head, particularly on the projected portions on the head during the downward vertical movement of the rail joints under traffic, resulting in the top projected portion of the head of the landing rail fracturing and causing flaking at the end.- Manufacture of Wear Resisting Liners by Welding Alloy Deposits on Mild Steel Plates

Austenitic manganese steel liners have the unique properties of developing rapidly a work hardened surface during service, while retaining adequate tough interior. Due to this work hardening characteristic, these liners have a property to withstand abrasion or sliding in service. As indigenously developed austenitic manganese steel liners are not abundantly available, Railways had to develop indigenous substitute for these liners.- TIG Welding of Defective Leaded Bronze Castings

Indian Railways are one of the major consumers of leaded bronze castings in the country. The necessity of a procedure for salvaging defective leaded bronze castings was felt when, in the foundries, due to minor defects viz. porosities, blow holes, small cracks etc. at or adjacent to the surface, castings had to be remelted resulting in the loss of metals, man hours, etc. Though the appropriate method for bringing down rejection is elimination of such defects by proper method study, a number still contain such defects, which can be reclaimed by welding.- International Welding Conference

The Indian Institute of Welding organised the Third International Welding Conference at the India Habitat Centre Auditorium, New Delhi in association with the Confederation of Indian Industry from 15th to 17th February, 2001. The Theme of the Conference was: “Advances in Welding and Cutting Technology”. It was co-sponsored by Engineers India Ltd., Oil & Natural Gas Corporation Ltd, Advani Oerlikon and MEMCO Ltd.
