Types of welding include MIG, TIG, stick, and flux-cored welding.
MIG welding (Metal Inert Gas) uses a wire electrode and shielding gas to join metal.
TIG welding (Tungsten Inert Gas) uses a tungsten electrode and filler rod with shielding gas.
Stick welding (Shielded Metal Arc Welding) uses a flux-coated electrode to create the weld.
Flux-cored welding uses a tubular wire electrode with flux inside to shield the weld.
I applied via Company Website and was interviewed in Mar 2021. There was 1 interview round.
Tube OD selection depends on factors such as fluid flow rate, pressure, and material compatibility.
Consider fluid flow rate and pressure to determine appropriate tube OD
Ensure compatibility of tube material with fluid being transported
Consult industry standards and guidelines for recommended tube OD sizes
Factor in any space constraints or installation requirements
Perform testing and analysis to verify tube OD selection
Pump selection depends on the fluid properties, flow rate, head, and system requirements.
Determine the fluid properties such as viscosity, density, and corrosiveness.
Calculate the required flow rate and head based on the system requirements.
Consider the pump type such as centrifugal, positive displacement, or axial flow.
Choose the appropriate pump size and material based on the fluid properties and system requirements.

Design parameters for heat exchangers include heat transfer rate, pressure drop, material selection, and flow arrangement.
Heat transfer rate: determines the efficiency of the heat exchanger
Pressure drop: affects the flow rate and energy consumption
Material selection: depends on the fluid properties and operating conditions
Flow arrangement: affects the heat transfer rate and pressure drop

Outages for line/switchyard are managed by the load dispatch centre through coordination and communication.
Outages are scheduled in advance to minimize impact on the grid and consumers.
Load dispatch centre coordinates with the concerned authorities to plan and execute the outage.
Alternative arrangements are made to ensure continuity of power supply during the outage.
Regular updates are provided to stakeholders regardin...
Double bus system is important for ensuring redundancy and reliability in power distribution.
Enhances reliability by providing backup in case of failure in one bus
Allows for maintenance work to be carried out on one bus while the other remains operational
Reduces the risk of power outages and downtime
Commonly used in critical infrastructure such as hospitals, data centers, and industrial facilities

The contact resistance of VCB is typically very low.
VCB stands for Vacuum Circuit Breaker.
The contact resistance is the resistance between the contacts of the breaker when it is closed.
The contact resistance of VCB is typically in the range of micro-ohms.
Low contact resistance is important for efficient operation of the breaker.
High contact resistance can cause overheating and damage to the breaker.
The contact resistan...
The resistance value of tripping & closing coil of VCB varies depending on the manufacturer and model.
The resistance value can be found in the manufacturer's manual or datasheet.
It is important to use the correct resistance value to ensure proper functioning of the VCB.
The resistance value may also vary depending on the voltage rating of the VCB.
For example, the ABB VD4 VCB has a tripping coil resistance of 50-60 ohms
The minimum height at which the safety belt should be used is determined by the height of the individual and the specific safety regulations in place.
The minimum height requirement for safety belt usage varies depending on the country and jurisdiction.
In the United States, for example, the minimum height for safety belt usage is typically around 4 feet 9 inches (145 cm).
Other factors such as age, weight, and type of ve...
