High frequency brazing diamond segment temperature and welding temperature control

Generally speaking, the temperature of high-frequency welding diamond segment should be controlled between 1200°C and 1500°C.
If the temperature is too low, the bonding strength between the diamond and the blank blade will be insufficient to achieve a firm weld; if the temperature is too high, it will cause excessive sintering of the diamond powders, which will affect its performance and even cause damage to the segment.

Therefore, in the high-frequency welding of diamond segments, it is necessary to control the temperature through reasonable process parameters, such as controlling heating time, current intensity, electrode diameter, welding pressure and other factors, to ensure that the temperature is within a suitable range. At the same time, it is also necessary to adjust the parameters in time through the monitoring and testing of the welding process to ensure the welding quality.

So how to ensure that the welding temperature is suitable, not too high and not too low?

To judge whether the welding temperature of the diamond segment is suitable, it is necessary to analyze and judge in combination with various factors. In general, the following aspects need attention:

1. Observe whether the diamond powders at the welding place fall off or crack. If it happens, it may be because the welding temperature is too high or the welding time is too long and needs to be adjusted.

2. Check whether the color of the welding place is suitable. If it is too bright or dark, it means that the temperature is too high or too low and needs to be adjusted.

3. Judging whether there is obvious deformation or discoloration at the welding place. If it is possible that the welding temperature is too high or too low, it needs to be adjusted.

4. Measure the temperature of the solder joint. If it is out of the proper range, adjustment is required.

In short, when welding the diamond segment, it needs to be adjusted according to the specific situation. By means of observation and measurement, it is judged whether the appropriate welding temperature has been reached, so as to ensure the quality and performance of the segment.

So how to control the temperature? Controlling the high-frequency welding temperature can be achieved in the following ways:

1. Control current and time: by adjusting the current and time parameters of the high-frequency welding machine, the heating time and heating intensity can be controlled, so as to achieve the purpose of temperature control.

2. Use temperature control system: add temperature control system in the high-frequency welding process, detect the temperature of the welding area in real time through the sensor, and feed the data back to the control system, so as to accurately control the welding temperature.

3. Use auxiliary heating equipment: add auxiliary heating equipment, such as infrared heating lamps, etc. during the high-frequency welding process, which can locally heat the segment, so as to achieve the purpose of temperature control.

4. Control the working environment temperature: the ambient temperature also has a certain influence on the temperature control during the high-frequency welding process, so it is necessary to control the working environment temperature at the welding site to avoid the influence on the welding temperature.
In general, when welding the segment, we must pay attention to the temperature control and the grasp of the heat, otherwise it is easy to cause the segment to fall, damage the segment and other problems.
