Tiny binoc transformer: are these leads brazed or welded?

Purely out of curiosity, I don't have a use case.

If they're brazed then it's very subtle. Perhaps they're vibration welded?  It looks like they've been squished but I can't see that alone being a strong enough bond.

It might be ultrasonic welding from the flattening of the ends.
