What is the Difference Between Brazing and Soldering?
- Soldering occurs at much lower temperatures, typically 150C˚ to 260C˚ (300˚F to 500˚F) while brazing is usually occurs at the range of 1200˚F (650˚C) to 2300˚F (1260˚C)
- Brazed joints are capable of handling stress and fatigue placed on the joints as opposed to the soldered joints.
- Brazing allows for intensive inter-alloying between the filler metal and the base metals resulting into a much stronger joint than that formed by soldering since it allows minimal inter-alloying between the filler metal and the base metals.
- Brazing requires a bigger overlap of the base metals in contrary to soldering which does not necessarily need a huge overlap between the base metals.
- In a soldered joint, the “cap” or fillet provides minimal additional strength while a brazed jointed needs to be fabricated so as to achieve a well-developed fillet or “cap” between the metal bases.
- The high temperatures involved in brazing causes the base metal to anneal or soften
- A brazed joint “makes itself”, in the sense that capillary action, rather than operator manipulation is responsible for the flowing of the filler metal completely through the joint.
- The filler metal used in brazing is more expensive than that used for soldering due to the different temperatures involved.
