HVACR Pipe Soldering Brazing - In HVACR there are two major types of soldering done. Soft Soldering for soldering water pipes and brazing or silver soldering for soldering refrigeration piping. There are various techniques for both types of soldering and everyone develops their own in the field but it is important to follow the basics of soldering when joining the piping together. Following the basics of soldering will ensure success and we all enjoy a successful job completed.
As always safety is first with anything. Two big considerations must be adhered to when soldering or brazing:
- Eye protection and burn protection for hot dripping soldering. Keep yourself safe when soldering or brazing.
- The inherent risk of using an open flame around combustible materials. Always make sure you have a plan and use preventive techniques such as wet rags and fireproof clothe or barriers. This is especially true when soldering around wood or even outside (around a condenser) where pine needles or leaves can easily catch fire and spread rapidly. Always have either a hose or fire extinguisher handy.
