Brazing Tungsten Carbide

Cemented carbide brazing is mainly aimed at wear-resistant tools with digging, cutting, crushing, milling, such as shredder hammers, mulcher teeth, milling teeth, cutting picks, stump grinder teeth, woodworking cutter, etc. These tools have bimetal structure features. The characteristic of this bimetal structure is that the cutting and crushing part is hard alloy, and the matrix is carbon steel or low alloy steel, usually medium carbon steel.
The bimetal structure can relieve the huge stress on this kind of workpiece, especially under compression bending, impact, or alternating load. Most hard alloy brazing tools are welded to medium carbon steel or low alloy steel substrates. The brazing process is closely related to cemented carbide and solder properties, and the brazing performance directly affects the use of wear-resistant tools.
JYF Machinery has focused on hard alloy brazing for many years, providing hard alloy brazing wear-resistant parts for many manufacturers of agricultural and forestry machinery, waste recycling equipment, basic rotary excavation equipment, road milling equipment, mining equipment, and other equipment.

Brazing tungsten carbide is the process of joining tungsten carbide tip or the tungsten carbide shank to the steel body. It is a process that brings two separate metals with a metallic filler, which is called braze. However, the top and the body must fit together neatly for the brazing to work. The metallic material will flow into the joint and to create a strong board that can be relied on even in the most demanding conditions.  One other thing that makes brazing tungsten carbide popular is that it makes a joint that is difficult to see.

Brazing is one of the most popular joining technology in the machine parts construction industry. It has a similar outcome as the soldering but it but creates a stronger joint. The technique is also different from the typical soldering in both the amount of heat needed as well as the metal that can join together. With this technology, you can utilize a vast range of heat and temperatures depending on what you want to achieve. Unlike soldering, brazing technology also enables you to twist, jolt and also shake the formed bond to get a perfect shape without compromising the quality of the joint.

There are many reasons why the JYF machine uses brazing with tungsten carbide. But the most obvious one is the strength of the joint offers when it comes to the construction of tungsten carbide tools. With alloy steel being the metal that we use for the body of our tools, it is understandable why this the best option that we have chosen for the parts. Brazing is the most reliable as well as the most effective way of forming two different metals together. That is why we have opted to use for all our aftermarket parts.

In our factory, we have invested in high quality equipment that ensures high quality bras zing joint. With most of the process automated, it is quite simple to do quality brazing tungsten carbide. For the technique to work, you only need to have the two pieces of metal (tungsten carbide tip and the steel body) brought together and braze flux is put between them. They are then heated to melt the braze flux to form the joint. However, we take various measures to ensure that we are getting the quality grade. Here are the basic steps of our brazing tungsten carbide:

  1. Cleans the surfaces of both the tungsten carbide tip and the steel body
  2. Applying influx to the steel surface
  3. Get the precut braze alloy steel and coat it with some influx
  4. Position the tungsten carbide tip or shank
  5. Start heating the braze alloy
  6. Move the tungsten carbide component slightly to allow the fumes or flux to escape
  7. Let the assembly cool down
  8. Use some hot water to wash off the excess flux

There are many benefits that come with tools that have been constructed using brazing tungsten carbide. These are just a few of them:

  1. Brazing does not melt the base joined metals as it is with welding; hence a clean joint which doesn’t need any form of secondary finishing.
  2. It can join non-similar metals as well non-metals
  3. Less thermal distortions due to the uniform heating
  4. Cost effective in brazing complex and multi-part assemblies
  5. You can coat brazing for protective purposes
  6. It excels in mass production and automated manufacturing
