Site Welding -Part 1 Tools, Equipment and facilities A compromise between equipment and production costs must be reached. Specialism welding equipment often requires experienced operators, who are not likely to be found or cannot be retained on the permanent basis, owing to non-continuous operations. Often even though a field training program for the use of such equipment is provided, the site welders resent change...

Introduction: Here we will discuss about the qualification tests for welders, economic choice of tools, the environmental contingencies of open air welding and quality control. There are innumerable factors which can be considered in regard to site welding so no single operational policy can be established to cover all site conditions. Therefore some of the factors affecting site welding in general will be discussed. Site...

Figure shows the general layout of a diesel engine power plant. The engine and its various auxiliaries systems are depicted with their proper positions. The flow path of air, fuel and gas are shown by arrows. The plant consists of the following: Engine Air Intake system Exhaust system Fuel system Fuel Injection system Cooling...

Diesel Electric Power Plants available in the range of 1MW to 50 MW capacity are used sometimes as central station for meeting small requirements and universally employed as stand by plant to supplement thermal power station or hydraulic station. Applications: The following are the applications of diesel electric power plants: Pick load plant: Diesel plants are suitable as pick load plants in combination with  thermal...
