I’ve never seen such an operation! Is it allowed from a safety perspective?

I watched another video; it seems there are similar cases in China as well, but they’re all special situations. Those working in oil fields might be aware of this

A welding method employed in special situations. Inert gas is blown in while welding to ensure safety.

This isn’t necessary; there’s a saying that it makes it safer to burn the gas

There are specific requirements for welding gas pipelines while they are still under pressure; generally, it is certainly not allowed to do so
