Welding Research Institute (WRI) was established in November 1975 by Government of India with UNIDO and UNDP assistance under the management of Bharat Heavy Electricals Limited, Tiruchirappalli, India. WRI has been constantly interacting with world renowned institutions for updating the knowledge base on latest technologies and assimilating experience.

This Institute has been established to cater to the welding needs of the Indian welding industries and for contributing to the growth of welding and allied technologies.


The major activities of the Institute include

Research and Development on various welding processes
Metallurgical Investigations
Dissemination of knowledge in welding
Consultancy Services


The Institute has the following recognitions to its credit

Recognized by Bureau of Indian Standards (BIS) for testing of welding electrodes
Authorised by Indian Boiler Board (IBR) for training and certification of welders
Well equipped laboratories accredited by National Accreditation Board for Testing and Calibration laboratories (NABL), New Delhi
Centre for Doctoral research recognized by Bharathidasan University, Tamilnadu, India.


The Institute is manned by experts comprising of 10 doctorates and 21 post graduates trained in different countries in the field of welding and allied areas and is fully equipped with the state of the art facilities. More than 6000 personnel have been trained and 2000 consultancy services have been completed covering 120 organisations. The type of industries served include Heavy Engineering, Power, Petro-Chemical, Transport, Metal Processing, Ship Building, Consumable & Welding equipment, Electronics industries etc.

Till date, technology transfer has been effected with the know-how for 9 products, around 18 Patents have been sealed, more than 50 Awards have been won and 600 Technical papers have been published in national and international journals. A reference book on Industrial Welding Technology authored by WRI has been published by Central Instructional Media Institute, (CIMI), Chennai for practicing welding personnel. The important research works carried out in the Institute are published in the Institute journal titled "WRI Journal".
