A soldered connection in residential wiring would be rare.

Applications where there is vibration would use insulated butt connectors 
although the crimpless type are popular. They use a low melting point 
alloy so its more or less back to a soldered connection.

For large industrial transformers or motors I used crimped ring tongue 
terminals. Those were fastened together with a screw and nut, wrapped with 
rubber tape, and then with vinyl electrical tape for abrasion resistance. 
Overkill but you really didn't want sparks from a 460 VAC junction box.
