WHAT IS BRAZING?
-
What is brazing?
Definition/description of brazing
Brazing is the joining process that relies on the melting, flow, and solidification of a brazing filler metal between the closely fitted faying surfaces of the joint by capillary action, to form a leak-tight seal, a strong structural bond, or both between materials. The components being joined undergo no melting Brazing is referred to as a joining processes performed using a filler metal having a liquidus above 840°F (450°C).
-
What is soldering?
Definition/description of soldering
- Soldering is a process whereby the filler metal (solder alloy) has a liquidus temperature below 450°C (842°F).
Advantages of soldering
- Low liquidus temperatures allow for correspondingly low process temperature (typically Δ20°C/Δ36°F above the liquidus temperature) that minimize heat damage to the base material(s).
- Solder joints can be “unsoldered” and resoldered to repair defects.
General requirements
- Molten solder must wet-and-spread on the base material (faying) surface(s).
- Wetting is the formation of a metallurgical bond between the solder and the base material.
- Fluxes are an integral facet of the soldering process.
- Surface finishes optimize wetting-and-spreading activity on hard-to-solder base materials such as aluminum, stainless steel, etc.
- Solder filler metal nearly always have a lower mechanical strength than the base material.
Soldering Applications
- Electronics applications: solder alloys are used in the assembly of electronic products that include individual device construction, printed circuit boards, and connectors.
- Structural applications: soldering is used to attach of conduit (pipes) together for a variety of application (potable water, chemicals, cryogenic liquids and gases) as well as for gutters and the fabrication of common light-duty products: e.g., cooking utensils, kitchen equipment and hand tools.
The following Industries use brazing and soldering in their everyday processes.
- Aerospace
- Automotive
- Electronics HVAC / Refrigeration
- Military applications
- Oil and Gas
- Construction
- Medical
