Brassing brass?

Question

When brassing two brass pipes together, how much heat is required and are there allowed to be gaps that can be filled in with the brass?
How do you join two brass pipes together?

Answer 1

If I remember properly soldering melts at 600-800 degrees. Brazing melts at 1800 degrees. Brazing is alot stronger

Answer 2

Brazing brass to brass is possible but,a little tricky since the rod & base material tend to melt at the same time.
I used an oxy- acetylene torch to get the required heat & fine" bare" brazing rod dipped into flux powder.
You can fill in gaps .....but carefully
Depends on what you're trying to repair.
Plain old soldering will work well with a connector like the ones used for copper water supply lines.
You could use silver solder as well but not without a connector. & lots more heat than lead soldering.
Butting the pipe ends together by brazing is not the way to go if the pipe is a supply line of any kind.
Ok if you are building something or for artwork.
Best regards

Answer 3

Permanent connecting is called Brazing. This method melts the main components and the filler rod to form one piece. Brass can also be soldered. Brazing requires high heat since you are actually melting the pieces.

Answer 4

You need just enough heat to melt the brazing rod. if the gap is less then 1/32 the rod should fill the gap with no problem. Use a flux coated rod that works well.
