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.
As part of our turnkey fabrication and assembly services, Triad Products offers silver soldering and brazing. We use these processes to join sections of bent metal tubing, fabricated sheet metal parts, and other metallic components. Few other tube bending shops provide brazing or soldering services, and none of them offer the proficiency and experience that we do.
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. By necessity, the filler must have a lower melting point than any of the metals being joined. Unlike welding, which requires that both pieces be made of the same material, brazing can be used to join mismatched metals such as aluminum and copper or nickel and steel. A properly brazed joint can be stronger than the pieces being joined, though not as strong as a welded joint.
Soldering is very similar to brazing, but 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 workpieces and creates a sturdy, permanent joint; soldered joints are not as strong as soldered ones. Like brazing, soldering can be used to join a variety of dissimilar materials, including copper, brass, iron, gold, and silver.
Brazing and soldering produce sealed, leakproof joints, with minimal physical effects on the treated workpieces.
