Temperature control of high frequency brazed diamond segment

When high-frequency brazing diamond segment, the most important welding elements are the following points:

Temperature control: It is necessary to control the welding temperature during welding to ensure that the diamond and the base material can reach an appropriate melting point. If the temperature is too low, the weld will not be strong, and if the temperature is too high, the stone may be damaged.

Pressure control: Appropriate pressure is applied during welding to make the diamond particles and the matrix material tightly bonded. Too low a pressure may lead to a weak bond, while too high a pressure may destroy the structure of the diamond grains.

Time control: The welding time should be long enough to ensure that the diamond particles and the matrix material are fully fused. Soldering times that are too short may result in weak joints.
In order to make the welding stronger, the following measures can be taken:

1:Select appropriate welding parameters: According to the characteristics of diamond and base material, determine the appropriate welding temperature, pressure and time.

2:Clean the surface: Before welding, ensure that the surface of the diamond and the base material is clean to remove impurities and oxides to improve the quality of the weld.

3:Use appropriate welding tools and equipment: Select appropriate high-frequency brazing equipment and tools to ensure stable welding energy and pressure.

4:Optimizing the welding process: Test and adjust according to the actual situation, and optimize the welding process parameters to obtain the best welding effect.

It should be noted that high-frequency brazing of diamond segments is a professional technique, and it is recommended to consult a professional diamond tool manufacturer or supplier before welding for accurate welding guidance and advice.

The welding temperature is so important, so the selection and control of the temperature is very important. Generally speaking, the welding temperature is determined according to the specific diamond segment and blank blade material, so the commonly used welding temperature will have certain differences. In general, the melting point of diamond is about 3550°C, but in the actual welding process, in order to avoid overheating and burning of the stone, the temperature is usually not raised to near the melting point. Because the diamond will undergo obvious carbonization reaction at around 700°C, and the diamond will slowly reduce to carbon. The longer the welding temperature, the more serious the carbonization of the diamond. During the cutting process, the performance of such a segment will be more and more seriously unstable. Therefore, for the stability of the segment, it is best if the welding temperature can be controlled below 700 degrees Celsius.

However, in a large number of tests, it was found that too low temperature welding may lead to weak welding, while too high temperature may cause diamond carbonization. Generally speaking, the welding temperature should be selected below the melting point of diamond, but high enough to ensure the fusion of diamond and blank blade material.

Of course, in order to take into account these two points, the best welding temperature must take into account the characteristics of diamond and blank blade materials, as well as the requirements and conditions of welding. Based on these considerations, people often set the temperature of high-frequency brazing at 700 -800 degrees Celsius is more suitable. It is a reasonable choice when the time is convenient and the welding with higher power can increase the welding speed of the segment more quickly and reduce the loss of diamond carbonization as much as possible.
If a specific optimal soldering temperature for a certain segment and a certain solder is required, it needs to be determined through a large number of experiments and tests, and the soldering temperature can be gradually adjusted and tested to find the optimal soldering temperature range. In addition, different diamond segments and blank balde materials may have different welding temperature requirements, so it is recommended to consult a professional diamond tool manufacturer or supplier before welding for accurate welding parameters and recommendations.
