Q2. What is the maximum contribution of lel for hot work
Ans. 
The maximum contribution of LEL for hot work is crucial for ensuring safety in potentially explosive environments.
• LEL Definition: Lower Explosive Limit (LEL) is the lowest concentration of a gas or vapor in air that can ignite.

• Hot Work Precautions: Before starting hot work, ensure LEL levels are below 10% to minimize explosion risks.

• Monitoring: Use gas detectors to continuously monitor LEL levels during hot work operat...read more

Q1. How is the pipe injected before argon welding?
Ans. 
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...read more
