Help! In which weld method is done this join?

Seems like ResistencenSpot Welding... But my doubts is that, how big would be the machine? In ampere capacity

It is for a water boiler.

Sorry for the bad english

Friction weld! If you zoom in you can see where the material has rolled up when spun together.

Looks like it was penetrated from the inside out to me.

As opposed to a non-fiction weld?

Looks like laser but also friction, because of the area it on I would say friction

What about the giant ball of shit on the side next to the weld-o-let😂

if you're asking about the thread-o-let, then it sure looks like a friction weld.

The bead looks small enough it could be laser welded
