Defects in Welding – Weldability and Testing of Weldments

Defects in Welding

Defects in Welding Process A welding defect is any flaw that compromises, the usefulness of a weldment. The improper welding parameters, base metal and selection of method introduce defects in the weld metal. So, the defective weld causes failure in service conditions and damages to the properties the defects in weld depending on thickness, load,

Directional Control Valves (DCVs) in Pneumatic System

Directional Control Valves (DCVs)

Directional Control Valves (DCVs) The primary function of any control valve is to direct, regulate the flow of fluid and regulate the pressure in various loading devices. Usually, directional control valves are used for sensing, processing, controlling which involves in the following functions. Controlling the flow by guiding and directing It to a loading line.

Pneumatic and Hydraulic Actuation Clamps

Pneumatic and Hydraulic

Pneumatic and Hydraulic Actuation Clamps Generally, the above mentioned pneumatic and hydraulic clamps are actuated by mechanical means. Sometimes, these are actuated by hydraulic or pneumatic methods where large production quantities are required. It facilitates faster clamping, uniform and equalised clamping pressure and less operator fatigue. It also provides an accurate controlling over clamping pressure.

Electrical Machine Design – Rotating Machines

Electrical Machine Design

Introduction – Electrical Machine Design Electrical machine design involves application of science and technology to produce cost effective, durable, quality and efficient machines. Also the machines should be designed as per standard specifications. The requirements like low cost and high quality will be conflicting in nature and so a compromise should be made between them.
