do you crimp?

[metalmeltr]

do you crimp the ends of acid core solder so the acid doesnt leak out?

[MoJourneyman]

I can't say i'm familiar with acid core solder, what applications does it get used for?

[NoeEttica]

Bee so many years since I used any ...

Can 'Ya still buy it ? LOL

it is the only thing ive ever used for soldering pipe-is ther something new that is used now?

[Vince the Plumber]

i think acid-core solder is for electronics only.

lead free solder for domestic (potable) water pipes.

rosin core solder is used for electronic

Just looked it up, the acid works as a flux. but before it's put into use the acid needs to be neutralized, Not something i'd recommend for potable water. I do see a lot of references to using it on dirty metals that can't be properly cleaned.

Most of us just clean our fittings and pipe, use a paste flux lead free solder.

when I have used acid core I have crimped the ends, but I find that normally there is not enough "acid" and one either needs to add some type of acid or flux on to the item to make it work, I do not think I have used acid core for 30 years, on any thing, but when I did I did crimp the end/ ends, when done using.

Acid flux is normally used for soldering more difficult-to-wet metals such as steel. It shouldn't ever be used for electronics because it's hard to get it all off -- some stays trapped in there and invariably the acid causes corrosion.

You don't need - and shouldn't use - acid flux for copper pipe. Copper is probably the easiest metal there is to solder. Normal lead-free plumbing solder and water soluble flux works fine, as long as you're careful not to overheat and burn the flux. Even though it's not as bad as acid flux, you should clean off any type of flux after you solder. By it's nature, flux is a very active compound. If you leave it on there, it will eventually corrode the material and cause problems.

Have never used it nor do I plan to I have seen it at the Depot butthat is as far as it goes

[Marklar89]

Bernzomatic and lenox still make acid core solder. (partly because they are both owned by newell rubbermaid). They sell it at wal-mart and home depot and it says on the pack to use it for misc metal repair like gutters and stuff and not for potable water. Never use anything that is not ASTM or NSF certified (or csa approved in canada) for use on potable water systems. As long as you follow this you will be fine. :)
