It doesn't sound as if this repair person knows exactly what he/she is doing. Harm can be done by, among other things, poor solder joints, excess metal removal on repeating the process, lack of neutralizing the acid flux, and finally, too much heating thereby annealing the metal. But the heating is the least of your worries, really. And, why was such a drastic repair made in the first place? This isn't something you do to an undamaged horn. Take your horn to a horn specialist, or at least a top-flight brass tech. If you want recommendations, you should ask this list or go to www.napbirt.org. I think, however, asking this list is your best bet.
