الوصف

  • All-purpose silver brazing alloy for copper alloys and steel.
  • It also has high mechanical strength, fine plasticity, electrical conductivity, and corrosion resistance.
  • Silver brazing rod has a 15% to 45% silver content.
  • Wider gaps can be filled with Safety-Silv 30, a filler metal with flow characteristics and a mild temperature.
  • Silver-copper filler metal is a cadmium-free alternative to more excellent silver-concentration alloys.
  • Affordable.
  • Good fillet-forming qualities.
  • Fills in connections where it is not possible to maintain strict clearance.
  • Made to braze steel, brass, and copper.
  • “Blue” is perhaps a description of the color of the flux coating on the rod. During brazing, flux is a substance that keeps the weld region clean and safe. Various flux colors can represent various applications or mixes.

Copper welding rods can be used to braze copper with brass or bronze, connect copper pipes and tubes, electrical wires, flexible tubing, and more. It operates at a temperature between 1,350 and 1,550 degrees Fahrenheit and has a tensile strength of 40,000 psi.

Pure copper wire can be formed into the desired shape by passing it through several dies to create a copper rod. Before being cut to length, it can also be shaped by running it through steel dies. This particular type of electrical conductor can benefit the construction of electrical cables.

The 30% Blue Rod Copper Welding Rod is a high-quality brazing filler metal used to join copper components. It is perfect for various HVAC, refrigeration, and plumbing applications because it provides a robust and dependable bond. The blue flux coating makes brazing easier because it helps to clean and shield the joint during welding. This post will go over the essential aspects of this particular brazing rod.

The Differences Between Welding and Brazing

First, it’s critical to understand the differences between welding and brazing. Welding forms a permanent connection by fusing the base metals. Conversely, brazing employs a filler metal that melts at a lower temperature than the base metals. The base metals do not dissolve; instead, the filler metal does and fuses the components.

آلية العمل

It is most likely a silver brazing rod perfect for combining copper, brass, steel, and stainless steel. It is described as a 30% Blue Rod Copper Welding Rod. It’s not a pure copper welding rod, even though it does contain copper. In silver brazing, components are joined without melting the base metals using a filler metal with a lower melting point. 

Strong brazing and superior electrical conductivity are provided by the 30% silver component. The blue hue can indicate a flux coating, which shields the molten metal during brazing and removes impurities. Cleaning the surfaces, heating the area, melting the rod to fill the joint, and using flux to encourage a solid and clean bond are all steps.

مزايا

  • Copper welding rods join copper pipes in homes, replacing hazardous lead-based solders and adding silver’s inherent antibacterial properties to the piping. 
  • It makes joints stronger.
  • Results in welded joints that are more appropriate for situations involving high temperatures.
  • Having the ability to unite both thick and thin metal portions (depending on process type).
  • Wide clearances can benefit from a melting range.
  • Frequently defined for official use.
  • Capillary flow and flexibility are good.
  • Its qualities include good wettability on hard alloys.
  • It performs well while welding has a small melting range, and is well-suited to brazing brass.
  • Requiring less power input and processing heat.
  • Creating joints with the least amount of residual stresses and heat distortion possible.
  • It does not need a heat treatment after processing.
  • Having the ability to combine different base materials.

سلبيات

  • Limited to joining (for most procedures, but not all) identical base materials.
  • Resulting in joints that are inappropriate for applications involving high temperatures.
  • Fluxes could include hazardous materials.
