A proper crimp, made with a ratcheting tool, using a quality connector, on the correct gauge wire, is a cold-weld. But you have to put a arrow through all of those rings for it to be such. I sometimes crimp, then solder. Depends on the application.
For automotive use, I like marine-grade connectors. Higher quality to fight off corrosion and nylon vs pvc plastic. Also marine-grade heat-shrink contains adhesive inside that waterproofs the connection.
Further, when I installed new auto wiring for my 2M/440MHz radio, I used Belden commercial grade tinned copper wire with a tough polyethylene insulation. Much better than bare copper and cheap pvc insulation. Easy to solder to as the wire is already tinned!
