Hi All,
This is one of those backwards questions. I do a hidden solder joint on some products, where the solder is encapsulated during assemble, then we put it on a simple steel mandrel, spin it with your finger and get it hot with a torch. Solder melts in the middle of the product and makes an excellent solder joint.
The problem is occasionally it solders itself to the mandrel, which is more of a pain in the rear, than a technical issue. Then you have to play with the mandrel, clean off the solder and work continues. Takes about 5 minutes to resume work, but this ends up happening 3-4 times per run or parts. Of course the steel bar it rusty, of course we spray it occasionally with graphite spray, but it's a ongoing thing.
Maybe it's a testimony to Harris SCLF16 Stay Clean Soldering Flux (liquid) and Harris Stay Brite silver solder, "able to solder in the toughest conditions" either way I', looking for a solution.
I was thinking about getting titanium tube for the mandrel, a little off the deep end, but as long as it solves the problem. I though about a graphite rod, but that would wear away, iron would rust fast with the flux.
So the question comes down to, do you think the solder would stick, and would the Harris liquid flux cause the titanium to corrode or do something weird.
Any thoughts would be great.
Thanks
Aaron
