How To Fix A Leaking Brazed Joint

When you solder a copper pipe, you’re actually joining two pieces of metal by melting a filler metal (solder) between them. The molten solder displaces any air in the joint, and when it cools, it forms a solid bond. A leak in a brazed joint can be caused by many things: an improper fit-up, dirty or rusty surfaces, an insufficient amount of flux, or simply poor soldering technique. But whatever the cause, there are several steps

How To Fix A Leaking Brazed Joint

There are a few ways to fix a leaking brazed joint. The most common way is to re-brazing the joint. This can be done by using a new piece of filler metal, heating it until it is molten, and then using a flux to help the new metal adhere to the old metal. Another way to fix a leaking brazed joint is to use a solder sealant. This is a sealant that is specifically designed for brazed joints, and

-A torch -Brazing rods – flux – wire brush

  • inspect the joint for signs of a leak. 2. clean the area around the joint with a brush and acetone. 3. apply flux to the joint and heat it with a torch until it begins to smoke

-Clean the area of the leak with a brush and acetone. -Apply flux to the area and re-heat the joint. -Apply new solder and heat the entire joint until the solder flows.


Frequently Asked Questions

How Do You Fix A Leaking Elbow?

If your elbow is leaking, you may have a cracked or corroded elbow joint. To fix the leak, you will need to replace the elbow joint.

How Do You Braze Holes?

Brazing is a welding process that uses a filler metal to join two pieces of metal together. The filler metal is melted and flows into the joint, where it solidifies. Brazing is often used to join sheet metal or tubing together.

What Is Braze Repair?

Braze repair is a type of metalworking that uses a furnace to heat the metal to be repaired until it is a liquid, then using a filler material to “solder” the two pieces back together.


In The End

The best way to fix a leaking brazed joint is to clean the area around the leak, re-bend the tubing if necessary, flux the area around the leak, and then braze the joint using a propane torch.
