Analytical Estimation of Welding Time BHEL (Tiruchi)'s Experience

1.1 Welding is the single major manufacturing operation at the High Pressure Boiler Plant Unit of Bharat Heavy Electricals Limited (Tiruchy Unit). Presently, 1,00,000 tonnes of components per year-(pressure parts and non-pressure parts for boilers and boiler house auxiliaries)- are being fabricated both at BHEL Works and sub-contractors' works. BHEL alone employs about 750 welders of whom nearly 200 are high pressure welders.

1.2 Planning and co-ordinating these welders' activities and associated welding equipment is a vital function and depends on the time estimation for carrying out various welding operations.
