ArcelorMittal Nippon Steel Interview Questions and Answers

Pascal's law states that pressure applied to a fluid in a closed container is transmitted equally in all directions.

• Pascal's law is important in designing hydraulic power packs as it helps in determining the pressure required to move the fluid through the system.

• The law also helps in calculating the force required to move the piston in the hydraulic cylinder.

• Designers must ensure that the system is designed to handle the pressure generated by the fluid.

• For example, if the hyd...read more

GD&T is a system for defining and communicating engineering tolerances. Welding types include MIG, TIG, and Stick, each with unique features.

• GD&T stands for Geometric Dimensioning and Tolerancing, and is used to specify the allowable variation in form and size of features on a part.

• MIG welding uses a wire electrode and shielding gas to join two pieces of metal together, and is commonly used in automotive and construction industries.

• TIG welding uses a tungsten electrode and fi...read more

Hydraulics is a branch of engineering that deals with the mechanical properties of liquids and their application in engineering.

• Hydraulics uses fluids to generate, control, and transmit power.

• It is used in various applications such as construction equipment, aircraft, and automobiles.

• Hydraulic systems are used in brakes, steering, and suspension systems in automobiles.

• It is also used in heavy machinery such as cranes, excavators, and bulldozers.

• Hydraulic systems are used in a...read more

Filtration systems are used in hydraulic to remove contaminants and prevent damage to the system.

• Contaminants such as dirt, metal particles, and water can cause damage to hydraulic components.

• Filtration systems remove these contaminants and prevent them from circulating in the system.

• This helps to maintain the performance and longevity of the hydraulic system.

• Examples of filtration systems include suction strainers, pressure filters, and return line filters.

Meter in and meter out circuit is a hydraulic circuit used to control the speed and direction of hydraulic actuators.

• Meter in circuit controls the flow of fluid into the actuator

• Meter out circuit controls the flow of fluid out of the actuator

• The circuit uses flow control valves to regulate the flow of fluid

• It is commonly used in hydraulic systems for controlling the speed and direction of hydraulic cylinders

• Meter in and meter out circuit is also known as a differential circui...read more
