Re-quoted for truth.
But, the OP was asking about doing some training for the electrical team, and this is the direction to go...especially in light of your comments about differring levels of expertise.
A pliers-like crimper (like what Richard Wallace linked to) can delver excellent crimps in experienced hands, which I think is what hobbes20xxxx is alluding to. But as James CH95 notes, our students are often not "experienced". Or as strong as a guy who twists 400 wire nuts a day. So, ratcheting crimpers offer greate consistency and repeatability.
Soldering is extra insurance, but if you allow solder to wick into the strands (under the insulation), you have what is essentially a solid wire...and we all know how those hate stress and straing, tending to break. So, unless it's soldered properly (neither too much nor too little) it is less reliable to also solder. Sometimes even I will over-solder a connection, but I can catch my error.
So, what are the other points improtant to cover with your students? (One related pair of points is "Bad crimps lose matches" and "only people who are trained are allowed to crimp".)
