How To SOLDER WIRES TOGETHER CORRECTLY

[@GarageDynamics]

Hey solder technicians! Let me know what's your favorite solder splice? Lap, Lash, or Western Union? I'd love to hear your thoughts. Feel free to leave a tip if you found value in this video 😊💲VENMO: @GarageDynamics Lap splice starts at 16:00 Lash splice starts at 21:00 Western Union starts at 26:00

I found the basic lap splice to be the most efficient when it comes to hand soldering like splicing 1 billion wires adding a custom ECU engine controller to a car. Over the past years I've done so many basic lap splices I now just free hand them, wire in one hand and iron in the other, and doing it quickly, and in awkward positions. The other wire is floating mid air tinned and ready to go, so the challenge is keeping a steady hand with the wire in your hand and is why not everyone can do it and needs mechanical support like lashing it, and consider the left / otherhanded control of beginners with any otherhanded task not just soldering. Helping hands is my pick for the best soldering accessory of all time btw.

[@GarageDynamics]

That's so awesome! You got your technique dialed! 💪

[@charlesbrewer6552]

By the way, regardless of the pronunciation, this is a great video on soldering. I have been doing it for 60 years!

[@GarageDynamics]

Thank you so much for the kind words. Coming from a 60 year veteran means a lot to me 🙏

[@chrisparker8539]

very informative!

[@GarageDynamics]

Thanks Chris!

I have always made my super splice by stripping about 3/8 off each sire, then butting the ends together so the strands interleave. Then take a single strand a tightly coil drawing it together into a nice package and then filling it with solder. Slide the shrink tube over or wrap with 3M Super 33+ and then you have a very clean, non-bulky splice. Absolutely perfect and never fails.

[@GarageDynamics]

I'm glad your technique is working for you

[@marksnethkamp8633]

Thanks for this. Wish it was around when I had to learn.

[@GarageDynamics]

You can always count it as a refresher course haha

[@marksnethkamp8633]

@@GarageDynamics 100% I still learned a lot. I am far from your level... This type of thing didn't exist when I was young. I was a kid with an AC radio shack iron with a bent tip who didn't know what flux was trying to fix my guitar amp with parts (also from radio shack) that looked like the exploded ones I found inside. As you can imagine I lost a lot of patients on that bench.

Im ready for nasa now ^^ ty!

I took a two week NASA soldering class. We used thermal strippers.

[@Flying0Dismount]

What does NASA say about solder wicking into the strands and creating a rigid/flexible junction in the wire where vibration (such as the massive vibrations encountered during space launch) could cause wires to break where the solder has made the strands rigid?

[@peterbonham5540]

They probably say use a crimp. From my experience much better

[@GarageDynamics]

Solder wicking up into the wire insulation would get rejected. Depending on the spec requirements, crimping would be the method of choice.

[@4samul]

Could you at some point explain how using lead-free solder differs from leaded solder

[@lohikarhu734]

For a butt splice, I try to prevent the solder "wetting" all the way to the conductor jacket, so that the splice maintains a tiny bit too flexibility at each end; the heat shrink normally stiffens the splice, but I think that the extra flexibility prevents bending stress on the soldered part, and possible crack development across the joint... maybe overkill, but I've worked in high vibration industries and automotive areas, where "overkill" is "just right" 😉 Also, I sometimes use a quality sealant inside the heat shrink, just enough around the splice so that the heat shrink action squeezes the sealant just enough to see it come out of both ends... again, just an extra for domains that get ambient water (like boats, rallye cars), or wash-down, as in food processing industries(normally we try to do splices inside waterproof boxes, but even "waterproof" has different meanings)

[@GarageDynamics]

You technique sounds solid! 💪 I agree, when it comes to soldering and reliability, overkill is always better than "good enough" 😉

[@lohikarhu734]

sorry for a multitude of comments, Burman hopefully not too "deppich": i had an employee who had worked on a satellite project, and taken the requisite NASA qualification courses, and he said that it was, at that time, forbidden to "wet clean" the soldering tip...not sure if that's still the case, just thought that someone else might comment. BTW, this fellow's soldering, great, but his soldering and heat shrink on big Mil circular connectors was true ART! And, he had also learned about building harnesses, crimping connectors, and harness "lacing"; it was a delight to have his skills seen in out projects!

[@GarageDynamics]

Your comments are always welcome here. That's so cool that you got to work with such a talented person! I would agree that "wet cleaning" a tip isn't good because it can shock the tip. But a very mildly damp sponge will be just enough to clean the tip without shocking it. A wire mesh is always a good alternative as well.

[@4samul]

​​@@GarageDynamicsWhat does shocking the tip mean? I'm very new to soldering and haven't heard about such a thing yet 🙏

[@johnleeke]

How about a link to those NASA standards?

[@lohikarhu734]

You should do it with lead-free solder, as well, otherwise any equipment with lead solder won't be ROHS certifiable

[@GarageDynamics]

Thank you for the comment

[@garybevis8691]

Lead solder is used in aerospace industries, lead free solder is not suitable for dependable solder joints for many varied reasons. FYI

[@RwP223]

Funny, the goal of my racecar build is to send it to the moon, and why I follow NASA standards when it comes to wiring splicing.

[@GarageDynamics]

Nice! I'll keep an eye out for it! 🔭

[@georgecavanaugh8757]

Come onnnnn bro, 4:08 in and still explaining stripping wire. Anyone who doesn’t know what stripping wire is, or how to do it, CANNOT solder a splice. Holy crap, 8:06 in and still nothing on soldering, come onnnnnnnnnn, the suspense is killing me. 12:03 and finally we’re seeing some prep for soldering.

[@GarageDynamics]

😅😂

[@Wranorn]

instead of a tutorial on soldering, its a tutorial on stripping wires.

[@RwP223]

A tutorial on how to paint a car will be 95% bodywork, bondo, priming, sanding, priming, sanding, repeat, repeat and then that 5% is laying down the top coats.

[@GarageDynamics]

It's both haha

[@GarageDynamics]

@@RwP223 Thanks! I love this analogy!

[@kozmaz87]

I am just using fulx-core solder for splicing wires and it is fine and much less hassle. It does it all well and works a charm. It would also help if the wire in this video was actually copper. But this is that weird aluminium-looking wire that solder generally has a tougher time sticking to properly or it is pre-tinned, not sure. In proper copper wires the solder wicks up much better (that isn't always good but very satisfying to watch)

[@marksnethkamp8633]

Its pre tinned wire. Its copper.

[@georgecavanaugh8757]

Holy hell, talk about dragging it out. Hey bud, none of us are get going to work for nasa. We’re just curious what their standards are compared to normal. A simple soldering video explaining the specs of nasa would have done. Wire stripping 101, wire strand discovery/explanation, and chemical analysis of slider joint. Great job, but just get into man.

[@GarageDynamics]

Thanks!

[@mustafazia9996]

If you take that long to tin a piece of wire Nasa will miss the launch

[@GarageDynamics]

🤣🤣🤣

I'd rather a crimp spliceor a Wago

I can never understand why Americans pronounce "Sarw-der-ring" instead of the way it is spelled "Sold-der-ring". In Australia and Britain it is "sold-der-ring", just the way it is spelled soldering! I don't understand why Americans can't pronounce this word?

[@marjoriegoldspur6798]

Alas, it's not just the word "solder". The fact is, there are literally scores of words that Australians/Britons pronounce differently than North Americans, the reasons for which confound any attempt at understanding.

[@michaelpariser2998]

Ok, Lieutenant thanks for the tip.
