How To Remove Old Solder From Copper Pipe

Soldering is the process of joining two pieces of metal by melting and flowing a filler metal (solder) into the joint. The purpose of soldering is to create a strong and permanent bond. When properly done, soldering is a very reliable method for joining metals. Copper pipe can be joined with solder through a process called sweating. In sweating, a flux is applied to the copper surfaces to be joined and then solder is melted and flowed into the joint. The

How To Remove Old Solder From Copper Pipe

The most common way to remove old solder from copper pipe is by using a propane torch. The heat from the torch will liquefy the old solder, making it easier to remove. Be sure to use caution when using a torch, as it can be dangerous. Another option is to use a solder remover, which is a type of chemical that will dissolve the old solder.

  • Apply solder to the copper pipe and wait for it to melt
  • Apply flux to the copper pipe and use a soldering iron to apply heat
  • Use a wire brush to remove any loose debris from the copper pipe

– Use a copper pipe cleaner to remove any built-up corrosion or oxidation on the copper pipe. – Apply flux to the end of the copper pipe and the solder joint. – heat the solder joint with a soldering iron until the solder liquefies. – Apply the solder to the joint and allow it to cool.
