    soldering VS. crimp and heat shrink

    If this has been on here before please add the link to this thread to it cuz i cant find it.. but anyway. just wanted to put my 2 cents on the topic as ive heard and professionally experienced a few different things. anyway on to debate.

    I used to work as a tech for VW and per factory regulations we were barred from repairing connections or wiring issues via soldering. Now this may be because of the quality and type of copper or whatever metal VW decides to use in all its harnesses, but due to that type of metal, resistance through that particular circuit is increased because of the solder. What have yall seen with BMW?

    We used crimps and shrink wrap to eliminate the inconsistencies in soldering that cause the increase in resistance in the circuit which can lead to a "false readinf that a component errored out." I would guess that its easier to calculate expected resistance through certain type of butt connectors when designating them for certain gauge wires....?

    Now let the argument begin!!:hitler:
    10 minutes... then we invade China.
    We'll begin with the small town of General Tso's,
    And move to the Orange chicken province.

    I'm on the crimp side of the argument.

      LOL....again, manufacturers all agree, solder is wrong in cars.

        ^^ this.... but to a certain extent i agree with the linked thread... it may be application specific... and the overwhelming majority of ppl dont know how to correctly solder... if solder at all (including myself) the other way i look at it is this.. when soldering (to get real scientific) about it i would think that the molecules of the soldered metal arent necessarily arranged in a perfect form therefore increasing or affecting resistance and voltage flow. where as a solid state preform butt connector has a predetermined shape to overcome any possible molecular arrangement issues that may affect resistance... if that makes sense?? or am i bass ackwards?? lol

          A properly executed crimp connection will be gas tight and as good as a properly executed soldered connection. But to to make a gas tight crimp you just about than the have tooling specific to the connectors used that make 360 degree crimps. Which really means a crimp tool for each sized connector or a crimp tool with replaceable dies. Generic connectors and the "squash it flat" tools just don't get it.

            We're not building NASA rockets here. While what you are saying is true, a "squash it flat" connector crimped with an at least decent tool meant specifically for crimping (ie, not your grandpa's pliers) with properly sized heat shrink will make a solid connection that should last as long as any of us will own these cars.

                I used to work in an electronics lab and we soldered everything. Although it was top notch stuff,$2500 soldering iron if you can believe that shit, and always used heat shrink over. The connections were inside of the MWD tools used for oilfield directional drilling and if they failed downhole thats $$$$$. Never heard of this debate though. I have a little of both on my car. All the recent stuff is butt connectors because I switched jobs and dont have the fancy stuff anymore. But it all works ;D

                  Perhaps this is why I have never had very good results with crimp fittings. I do solder and shrink wrap but by using a very tight rat tail splice Im quite confident that I have good copper to copper contact. The solder is just molten shrink wrap to my mind. This makes more sense to me than adding a piece of aluminum between 2 wires.

                    ya I mean everybody has their own way of doing things with different results. Ive never learned to solder which is probably one of the reasons im not very fond of it... but working in the factory automotive setting... we never soldered and probably for good reason. but I digress...
