    Hi plumbers, I am popping here today to ask how do I solder a clean join? For example I am currently in the process of creating a lamp for my living room out of copper pipe. I started to solder today and realised I'm crap :smile5:. I cleaned the pipe and the elbows and fluxed, but no matter how hard I tried the solder went everywhere and I ended up with proper messy pipe joins.

    I would like to create something like the following:

    as you can see the joins are spectacular and look very clean and nicely done. My question is how??

    thought I'd ask plumbers as you may know?

    Use the flux sparingly and only a small amount of solder, you only need to hold it together it's not water tight you're after is it !

    Use propane, lead free solder warm the fitting and tube, allow the heat of the metal to melt the solder, NOT THE FLAME.

    hope that helps, You can of course use leaded solder but make sure it's clean

    Post up some pictures of what you had done, don't worry if its bad. That will give some idea of where you are going wrong. Also tell us what equipment you have and the materials your using.

    Also if your doing this you may want to post up on the electrical forum to confirm electrical/earthing requirements.

    Thanks for the quick reply.

    Is there a reason to use flux sparingly?..

    I have been using butane? Not propane? Heat is heat right? Obviously I'm wrong so tell me lol.

    What's the difference between lead and lead free solder in my case?.

    Here is a sample join:

    I'm not embarrassed, would just love my joins to look better than the above.

    I'm using a butane gas torch.. cheap. Lead free solder and flux with some pipe cleaning paper.

    Thanks for your help.

    It takes time and practice

    Sounds like you need to heat the fitting more as the solder should suck into the fitting

    Clean and flux both (pipe and fittings) once assembled wipe excesse flux off

    Heat from front add solder from the back about 1mm (length) of solder should do

    It does suck into the joint. I can see it doing that, but I'm also using 3mm diameter solder is that too much?

    Yes doesn't need to be much as its not holding anything just a physical connection

    I do not want to glue. I prefer to solder as I kind of like the look. Gluing is fine for some joints but not for others.

    Do you recommend getting a smaller diameter solder wire?

    Use Yorkshire fittings, pre loaded with solder, just need to flux and heat up.
