BTW, a good job of crimping amounts to cold welding with the extra
bonuses of high mechanical strength and inherent disruption of oxide
films or dirt on the connector or the wire. Given my choice, I'd pick a
well-crimped connection over the other two, but I would not worry about
a good job based on the other two methods. Crimping and welding have the
disadvantage of not being as field-repairable as soldering.

The other beauty of crimping is that there is no weakening due to heat
close to the joint - perhaps not that important where the lead is
adequately clamped, though.

I don't understand your reasoning.
Electrical copper is, or should be, in a completely annealed state. Heating
the copper up isn't going to hurt it.

I have found, however, that soldered cable connections frequently break from
strain, even if they are correctly soldered. Connections are frequently
repaired over again, due to inadequate strain relief on the center conductor
that appears in large diameter coaxial cable.
