Male Adapters & Ball Valve Soldered Correctly onto Cold-water Inlet & Hot-water Outlet Pipes?

[DIYEnthusiast]

Seeking second opinions on whether joints/connections look secure. Recently had a plumber do the following:

(1) Remove corrugated copper pipes and solder on male adapters for stainless-steel connector.
(2) Remove old cold-water supply shut off valve and solder on lead-free copper-alloy ball valve (KITZ No. 858 600 WOG).

Warranty is three months.

What is your overall assessment of his or her workmanship?

Appears to me to be a workmanlike job. Not the prettiest solder joints in the world, but, then again, like a milk cow, they don't have to be pretty. I'm assuming the flex pipes have a rubber washer, so teflon tape on the threaded joint not necessary.

I agree to a certain extent, however, if I understand the scenario correctly, the male adapters were removed and re-soldered.
When one removes an existing fitting the pipe and ftg should be well cleaned prior to re-fluxing and soldering.
Not sure what that person did. Looks like maybe overheated a bit. ???
