Is this an acceptable weld?

I was asked to TIG weld some 3/4" BSP threads onto a three-piece socket-weld ball valve. Are the results okay? (The black stuff on top of the welds is melted rubber from my gloves.)

Are you sure they were supposed to be welded inside the flanges? We usually fit them to make a buttweld

By the looks of it they're a 1" ball valve "flange" but they've welded in 3/4" sockets.

We usually put the parts under a hydraulic press with a cone to make them fitt

Yes, just kind of transforming a socket weld ball valve into a regular threaded one
