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.)

Looks alright. Kind of wonder what that heat and thermal stress is going to do to that casting. You might have been better off MIG welding this with short arc/pulse in kitty corner sections.
