I got away with one of these for many years:
Then I graduated to one of these for the automotive style spade connectors etc (Much easier to use, better crimp, but less 'features' as above):
For Heavy stuff I use one of these lug crimpers, realistically, if you only have a few connections to make, visit your local friendly auto elec, and throw a few bucks at him to make the crimps you need:
If you are going to work on massive stuff, the above is also available in a hydraulic version... but I don't see you needing it.
Crimping is a mechanical process, but what actually happens in the larger hex style crimps, is the copper conductor cold welds together.

I use a torch for 5+mm wires, and small superscope iron for smaller wires. Once soldered they are "done" for life as far as I can tell (unless it's a wire that moves a lot, if it does the wire will fatigue and break at the end of the soldered joint... eg: wiring plugs from engine -> firewall where there isn't enough flex in the wires). If it's somewher the wire is tied down and never moves ... heat shrink and solder IMO is a the most permanent fix out there
