I applied via Naukri.com and was interviewed in Jan 2024. There were 2 interview rounds.
The pipe is injected with argon gas before welding to create an inert atmosphere.
Before welding, the pipe is purged with argon gas to remove any oxygen and moisture that could contaminate the weld.
This is typically done using a purge gas system that fills the pipe with argon and then vents it out before welding.
Purging with argon helps prevent oxidation and ensures a clean, strong weld.
Proper purging techniques are ess...
Metals such as stainless steel, carbon steel, and aluminum are commonly used before the welding process.
Stainless steel is often used for its corrosion resistance and durability.
Carbon steel is commonly used for its strength and affordability.
Aluminum is lightweight and has good conductivity, making it suitable for certain applications.
Dimensions of the elbow of unknown degree are calculated using trigonometry and geometry.
Calculate the centerline radius of the elbow.
Use trigonometry to find the length of the elbow.
Consider the angle of the elbow to determine the dimensions.
Measure the outside diameter and wall thickness of the pipe for accurate calculations.

There are several types of pipes used in fabrication, including steel, PVC, copper, and cast iron.
Steel pipes are commonly used in construction and industrial applications.
PVC pipes are often used for plumbing and irrigation systems.
Copper pipes are used for water supply lines and heating systems.
Cast iron pipes are typically used for drainage and sewer systems.
The question is unclear and lacks context.
Can you please provide more information about the context of the question?
What is the purpose of the 10inch pipe outside the meter?
Is this related to a specific project or industry?
Without more information, it is difficult to provide a meaningful answer.
P&ID stands for Piping and Instrumentation Diagram.
P&ID is a detailed diagram that shows the process flow, equipment, and instrumentation in a piping system.
It is used in engineering and construction projects to understand and communicate the design and operation of the system.
P&ID includes symbols and labels to represent various components such as valves, pumps, instruments, and control loops.
It helps in identifying p...
