INTRODUCTION
In 1956 India took a major step towards the establishment of its first heavy electrical engineering manufacturing plant at Bhopal. It progressed rapidly and three more factories went into production in 1965. In 1969 BHEL supplied its first unit to Basin Bridge Thermal Power Station in Tamil Nadu. Within a decade BHEL had commissioned the 100th unit at Santaldih,WB.
The present scenario of BHEL consists of 11 manufacturing divisions, 9 service centers, 4 power sector regional center, about 350 large consumers(in India ) and many countries also. The companies inherent potential coupled with its strong performance make this one of the “NAVRATNAS”, which are supported by the government in their endeavor to become future global players.

WORK UNDERGONE & EXPERIENCE
During my training period at the block-2 I came to know about the main processes which went through the block.Most of the manufacturing process have been told about earlier. Some more machineries and processes are given here.Some of them were like plasma cutting, NDT testing, Hydraulic presses,turning, gas cutting etc.
The various processes and machinery are as follows:
A)Hydraulic Press:A hydraulic press is a hydraulic mechanism for applying a large lifting or compressive force. It is the hydraulic equivalent of a mechanical lever, and is also known as a Bramah press after the inventor, Joseph Bramah. Hydraulic presses are the most commonly-used and efficient form of modern press.
The hydraulic press depends on Pascal's principle: the pressure throughout closed system is constant. At one end of the system is a piston with a small cross-sectional area driven by a lever to increase the force. Small-diameter tubing leads to the other end of the system. A fluid, such as oil, is displaced when either piston is pushed inward. The small piston, for a given distance of movement, displaces a smaller amount of volume than the large piston, which is proportional to the ratio of areas of the heads of the pistons. Therefore, the small piston must be moved a large distance to get the large piston to move significantly. The distance the large piston will move is the distance that the small piston is moved divided by the ratio of the areas of the heads of the pistons.
