Question

Solder not working it's way to where I need it.


I am doing a test solder on a piece of copper pipe. I am using a microtorch and I am using a laser thermometer to test the temperature of the pipe.

The pipe is getting to above 700 degrees. The melting temp of the solder (Lenox) is 419 degrees. Yes I cleaned, sandpapered and fluxed the area real well but I cannot move the solder around at all. The solder does eventually drop off of the roll (melted) but it does not flow anywhere. Do I need more flux, more heat? Thanks.

Tripower,

Have you got "standing water" in that copper pipe? If so you'll have to remove it to complete the solder project.

It sounds like you're getting it to hot. But... after you clean both pieces make sure you don't touch them with your fingers. The oil in your skin will contaminate the joint. Both pieces need flux. Now you're ready to solder. Only heat the fitting and NOT the pipe. You don't need a tremendous amount of heat, only enough to melt the solder. I always wait until I see the flame on the backside of the pipe turn color. (usually green) Now remove your flame and add solder. It will take practice but you'll get the hang of it pretty quickly. If you get the pipe to hot it won't draw the solder and will just run off the pipe. Good luck.

Solder melts at around 400 degrees. If you hit 700 degrees you're boiling your flux right out of the joint. Apply the solder to the joint at the opposite side that's being heated. The solder will flow toward the heat.

Let me try this again. This micro-torch should be enough to sweat this small copper fitting right?

If you are getting it up to 700 degrees, it is MORE than enough. Heat the fitting where you want the solder to travel to. If too hot, you will burn up the fitting (after boiling out all the flux).

The micro torch might (I don't know for sure) take too long to get the fitting hot enough, even though it is capable of getting it hot enough...Meanwhile your solder is liquifying, boiling, and disappearing. When soldering pipe, timing is critical. Too hot too quick isn't good but too hot (or even perfect heat) too slow isn't good either.

You can get a propane torch for very little money...Maybe $20. I'd keep the micro torch for electrical soldering and get an inexpensive propane torch for soldering copper plumbing fittings.

Some say you can stick a breada crumb in there to absorb the moisture and it will wash away.
I always open a tap down line to let the water flow back and drain. Worst acse you could try a aiming a hair dryer in there or wad a clean dry rag into the joint but that seems extreme unless your joint is working as a trap between two higher spots.

get any water out, get rid of the micro torch, heat the fitting, if its too hot youl figure it out as the solder will just run like water, maybe like 7 seconds on a 3/4 inch line is about all you need to get started .than heat breifly as needed to keep it flowing. use the flux brush with some flux on it to cool/ clean the joint after you are done

I closed up all of the main line coming into the house and I opened up all of the faucets but I am still getting a constant dribble. The breadcrumbs sounds like an idea but I need to think about that.

Not bread crumbs, bread! Lots of it. Use white bread only (wheat pieces will get caught in aerators, white bread won't). Pull off the crust and ball it up tightly about the size of a nickel. Jam it into the pipe where the water's coming from and push it 3 or 4" up the pipe with a pencil or something.

When you turn the water back on the doughball will liquify and will instanty run out of the lines. It works great.

I tried once to heat a pipe that still had some water left in it. I opened all the faucets and tried draining the pipe but when you heat the pipe it makes any little bit of water run towards the place your heating and even a little drop will ruin the joint. I've never tried the bread trick but next time I run into a pipe that still has water in it I will try that. If water is what is causing your problems you wouldn't believe how much can come out when you heat it even after you think you drained it all. Other than that everyone else gave good help on soldering. good luck

Yeah the water is becoming a real issue. I am going to the store for some Wonder bread. How is this water getting into this line though I shut everything off and opened up ALL faucets.

There are a number of spots the water is probably "sitting" in the pipes. I was amazed at how much water ran out of the pipes after everything was turned off and "drained". Seems like when you heat the pipe up the water flows towards the joint your working on. Just remember to take the screens off the faucets and anything down line from where you are soldering when you flush the bread out of the lines.
