BEKEM Infra Projects Interview Questions, Process, and Tips

Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.

• Ohm's law is expressed as V = I * R, where V is voltage, I is current, and R is resistance.

• It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.

• For example, if a circuit has a voltage of 12V an...read more

Voltage is the electrical potential difference, current is the flow of electric charge, and frequency is the number of cycles per second in an alternating current.

• Voltage is the measure of electrical potential difference between two points in a circuit.

• Current is the flow of electric charge through a conductor, measured in Amperes (A).

• Frequency is the number of cycles per second in an alternating current, measured in H

Welding is a fabrication process that joins materials, typically metals, using high heat to melt and fuse them together.

• Arc Welding: Uses an electric arc to melt the workpieces, e.g., Shielded Metal Arc Welding (SMAW).

• MIG Welding: Metal Inert Gas welding uses a continuous wire feed and inert gas, ideal for thin materials.

• TIG Welding: Tungsten Inert Gas welding provides high precision and is suitable for stainless steel...read more

ASME Codes and Standards ensure safety and quality in engineering, particularly for pressure vessels and piping systems.

• ASME stands for American Society of Mechanical Engineers, which develops codes for mechanical engineering.

• Key standards include ASME Boiler and Pressure Vessel Code (BPVC) and ASME B31 for piping.

• These codes provide guidelines for design, materials, fabrication, and inspection.

• Example: ASME BPVC Secti...read more

NDT procedures are essential for assessing material integrity without causing damage, widely used in various industries.

• Common NDT methods include Ultrasonic Testing (UT), Radiographic Testing (RT), and Magnetic Particle Testing (MT).

• Ultrasonic Testing uses high-frequency sound waves to detect internal flaws in materials, such as welds.

• Radiographic Testing involves X-rays or gamma rays to visualize the internal structu...read more
