Welding Training Centre

Welding is one of the most frequently used processes in Railways both in production as well as in maintenance. The Lab is equipped with the state of the art welding sets and trainees can have hands on experience on various welding methods viz.

1. Manual Metal Arc Welding

2. Resistance Welding

3. CO2 Welding

4. TIG Welding

The Multimedia e-Learning Software on the specific welding operation, welding defects- causes and remedy, welding inspection etc. is supplied along with equipment. The wall charts on welding symbols and illustrated processes complete the learning in welding.

The lab is fully equipped with a set of 13 illustrative posters on various welding methodologies / processes, symbols, electrode selection / identification, welding defects and causes of the same.

Metrology Centre

Metrology laboratory consists of various measuring instruments Viz. Sine Bar, Limit Plug Gauge etc. The training equipments are supplied with the multimedia e-Learning Software to form a complete Blended Learning System.

e-Learning Software for understanding the quality aspects of material such as Rexene, Rubber etc. and testing of the same is provided. The software is in English & Hindi and provides explicit details of the concerned standards used for accepting the material.

Refrigeration Air-Conditioning Lab

Railways use both Air Conditioning & Refrigeration for passenger comfort & food preservation. The Railway Engineers and Technicians who are responsible for maintaining the coaches & wagons need to be trained in Air Conditioning & Refrigeration. The training equipment is supplied with the Multimedia e-Learning Software to form a complete Blended Learning System.
