Custom Brazed or Soldered Tubular Parts & Assemblies

Used to join similar or dissimilar metals, brazing and silver soldering are challenging processes that are part science, part art. They require skill and experience, as melting temperatures need to be closely monitored and materials have to be carefully handled to ensure the quality of the resulting joint. If brazing or soldering is done at too hot or too cold a temperature, the process can fail. What’s more, these processes cannot be performed by robotics or CNC technology—skilled, human operators are required to get the job done correctly.

With more than 40 years of experience in the areas of brazing and soldering, you can count on Triad to deliver the reliable results only few experts in the industry can. Our highly proficient welders can provide you with custom brazed or soldered parts skillfully engineered according to your exact specifications.

Brazing vs. Soldering

In brazing, a filler material is heated and melted into seams or gaps between two (or more) metal pieces to permanently bond and join them. This process utilizes higher temperatures compared to soldering and requires a silver alloy with a higher melting point than any of the metals being joined.

While very similar to brazing, soldering uses filler materials that melt at lower temperatures (840°F/450°C or lower). This filler, called solder, is melted into seams or gaps between the metal pieces, and, as it cools and solidifies, bonds to the workpiece and creates a sturdy, permanent joint.

Brazing and soldering both produce sealed, leakproof joints, with minimal physical effects on the treated workpieces. Brazing and soldering can be used to create anything from gas and fluid transfer components to PCBs and other electrical conduits.

The Right Process for Your Application

Triad’s expertise in soldering and brazing includes knowing which process is right for the project at hand. Depending on the materials involved and the performance and application requirements, we will determine which option is best for your products.

Brazing of Ferrous Metals

Advantages:

  • Component tolerances are maintained
  • Produces a clean joint with little to no finishing required
  • Capable of joining thinner sheets and pipes
  • Provides excellent sealing characteristics
  • Produces superior accuracy and aesthetics compared to soldering

Disadvantages:

  • Joints are not effective at higher temperatures
  • Joint is often weaker compared to welding
  • Requires a flux
  • Not suited to large plates of metal 

Low-Temperature Silver Soldering

Advantages:

  • Requires low power and low process temperature
  • Base metal does not melt
  • Microstructure of metals is preserved
  • Joints can be dismantled
  • Low cost and time efficient

Disadvantages:

  • Strength of joint is less than in brazing
  • Not suited to long length materials or heavy metals
  • Produces less accuracy than brazing
  • Requires a flux
