Yes, welding something to a biner will ruin its heat treatment and weaken the biner, now how much it weakens it is not a question I can answer.
and I have to laugh at the bolded part;)

Gram,
Was the metal steel or aluminum? What exactly was the carabiner used for? The effects of welding aluminum starts at about an 80% drop in strength. Steel not so much given it was done properly. There is way to many variables in welding to make any judgments based on what you saw. In my experience most people who own a welder do not have the knowledge to properly use it, this is why I would give strong caution in this case.

Sorry, was the welded carabiner part of your attachment system or just there to provide a handle?
Also, aluminum is very hard to weld, so, if steel was used, that gives a considerably larger margin of error for bodyweight only applications.

At least they used a rod with vigor and stamina

I've seen steal biners with welded bars and think they are probably okay provided they were done by someone who knew what they were doing (ie don't buy cheap imported welded steal biners from unknown manufactures).
The problem with welding high strength aluminum is that it is often heat treated and welding removes this effect leave. For aluminum bikes they often heat treat the whole frame after welding...i suppose something similar could be done with aluminum carabiners but it is probably easier to get the same effect in other ways.

Well, this is fun. Something I actually know. Firstly, I am pretty sure you cannot weld aluminum to steel. As mentioned, both possibly OK before heat treating and such, but unlikely that they did that. Chances are they would just make it correctly first time. Secondly aluminum, generally takes massive heat (TIG) and you'd need to be a real pro to control that and avoid warpage of the biner.
