Welding Research Institute, BHEL, Trichy

The Welding Research Institute (WRI) is the premier national research centre of India in the field of welding and allied areas.  WRI was established by Government of India under the aegis of the Bharat Heavy Electricals Limited, Tiruchirappalli, India, a premier public sector undertaking with the assistance of UNIDO / UNDP. The institute has assimilated high level of technological excellence in nearly four decades and has assisted the Indian industries in applying the latest welding and allied techniques to upgrade quality & productivity. This institute has been established to cater the welding needs of the Indian welding industries and for contributing to the growth of welding and allied technologies. Since its inception on November 1, 1975, WRI has been constantly interacting with world renowned institutions for updating the knowledge base on latest technologies and transferring it to the Indian industry sector. The major services rendered by WRI to the industrial sector includes: Research and Development in establishment and application of various welding processes catering to the appropriate needs of industries, serving varied sectors. It is indulged in carrying out metallurgical investigations including Failure Analysis, and remnant life assessment. Other than research and development it also focusses on dissemination of knowledge in welding and allied areas through Training, documentation services, publications and Journal authored by field experts of WRI. The expertise of WRI is proved by its holistic consultancy services and solutions to industrial problems through long term MOUs and one time contracts. It has well equipped laboratories accredited by National Accreditation Board for Testing and Calibration laboratories (NABL), New Delhi. The type of industries they serve include Heavy Engineering, Power, Petro-Chemical, Transport, Metal Processing, Ship Building, Consumable & Welding equipment, Electronics industries etc. The important research works carried out in the Institute are published in the Institute journal titled "WRI Journal". Expertise of the Institute encompasses the following: (Source: http://www.bhel.com/wri/institues.php)
