Tungsten tin gravity separation method

Tungsten tin gravity separation method

Tungsten tin electrode is currently one of the most commonly used materials in electronic welding. It has characteristics such as high melting point, high hardness, and high density, and is widely used in semiconductor, electronic components, aerospace and other fields. And tungsten tin re selection is a common processing method for tungsten tin electrodes, which can make the electrode surface smooth again, improve the electrode's service life and welding quality.

This article will introduce the methods and steps of tungsten tin re selection, to help everyone better understand and master this processing technology.

1、 Preparation work

Firstly, we need to prepare the following tools and materials:

1. Tungsten tin electrode

2. Tungsten tin gravity separator

3. Grinding wheel

4. Sandpaper

5. Gloves

6. Safety glasses

7. Protective mask

2、 Operating Steps

1. Place the tungsten tin electrode into the gravity separator and start the machine. Select the corresponding grinding wheel for processing based on the diameter and length of the electrode. Generally speaking, the smaller the diameter of the electrode, the finer the particles of the grinding wheel need to be.

2. Adjust the height and angle of the grinding wheel to make it in contact with the electrode surface. Generally speaking, the height of the grinding wheel should be parallel to the surface of the electrode, and the angle should be between 5-10 degrees.

3. Start processing. Place the electrode on the grinding wheel and rotate and move it with appropriate force. Be careful not to use excessive force, as it may damage the electrode surface.

After processing, gently wipe the surface of the electrode with sandpaper to remove residual grinding wheel particles and dirt.

5. Check if the electrode surface is flat and smooth. If there are uneven areas, they can be processed again.

6. Finally, wipe the electrode clean with a clean cloth and return it to its storage location.

3、 Precautions

When conducting tungsten tin re selection, it is necessary to wear gloves, safety glasses, and protective masks to prevent damage from grinding wheel particles.

During the machining process, attention should be paid to controlling the force to avoid damage to the electrode surface.

If there are significant unevenness on the surface of the electrode, it can be polished with sandpaper first to avoid uneven grinding with the grinding wheel.

After processing, it is necessary to clean the electrode surface to avoid residual grinding wheel particles affecting the welding quality.

4、 Summary

Tungsten tin re selection is a common method of processing tungsten tin electrodes, which can make the electrode surface smooth again, improve the electrode's service life and welding quality. When conducting tungsten tin re selection, attention should be paid to wearing personal protective equipment, controlling the processing force, and avoiding damage to the electrode surface. After processing, clean the electrode surface to avoid affecting the welding quality.
