Here Are The Main Step Of Brazing Carbide To Steel

Brazing carbide to steel is one technique used for the construction of the cutter tools. The technique is used for the forming of the joints between the tools body and the carbide material. As the name suggests, the technique includes heating the braze ally and making the steel body’s carbide combine to form a strong joint.

But how does the brazing carbide to steel works? Well, there are main steps that are taken to ensure the quality joint is formed. Here are the main steps:

Step 1: Getting The Assembly Ready

The first step in brazing carbide to steel is getting everything needed for the brazing tungsten carbide. You need to have the carbide and the steel. These are the parts that make the cutting tools. The other thing you need is flux. This is material will enable the heating and melting of the metals to be joined. The next thing you need to get is the source of the heat. With these things, you are ready to continue with the brazing work.

Step 2: Flux Steel Surface

The second step (and the first one) when brazing carbide to steel is applying flux on the steel. This should be done with a lot of care to avoid foreign particles on the surface. That’s why it is recommended that you first clean off dirt, dust, and other particles on the steel body. The flux should be applied lightly.

Step 3: Insert Braze Alloy

The third step is bringing the braze alloy metal to the steel and make sure that it is also lightly coated with flux. It is important to note that the blaze alloy material is the one that will help form the joint upon heating.

Step 4: Position Carbide Tip

The next step is to position the carbide tip in the assembly. The carbide component must also be coated with the flux. Now you have the three components together with brazing alloy at the middle. From this stage, we go to heating.

Step 5: Heating

The heating stage is very crucial because it determines the quality of the joint. Make sure that the heating is done evenly throughout the assembly. You must also ensure that proper temperature is used.

Step 6: Making The Joint

Once the braze alloy is heated to molten form, jiggle the carbide slightly just to allow the fumes and flux residues to escape. Avoid pressing firmly to prevent weakening the joint.

Step 7: Cooling

Allow the assembly to cool naturally. This is good for heat treatment and improving mechanical properties. Do not attempt cooling quickly, as this will weaken the formed joint.
