For mechanical damage to tungsten wire, the repair method mainly depends on the degree and location of the damage. The following are some common repair methods:
- Repair of minor damage
For minor scratches or wear, the following methods can be considered:
Surface treatment technology: such as chemical or electrochemical cleaning to remove stains and oxides on the damaged surface and restore the surface finish of the tungsten wire. This method is suitable for situations where the damage is minor and does not affect the overall performance of the tungsten wire.
Local polishing: Use fine sandpaper or polishing paste to locally polish the damaged area to reduce the depth and width of the scratches and improve the surface quality of the tungsten wire. However, it should be noted that excessive polishing may cause the diameter of the tungsten wire to become smaller, affecting the use effect.
- Repair of severe damage
For severe mechanical damage, such as fracture or large-area wear, more complex repair methods are required:
Welding repair:
TIG welding: TIG (Tungsten Inert Gas) welding, that is, tungsten inert gas welding, is a high-quality welding technology. It can produce high-quality and uniform welded joints and is suitable for repairing tungsten wires. When using TIG welding, it is necessary to ensure the stability of the tungsten wire welding position and the cleanliness of the electrode to avoid affecting the welding quality.
Argon arc welding: Argon arc welding is an arc welding method that uses argon as an inert gas, which is also suitable for repairing tungsten wires. It can achieve the connection of tungsten wires with other metal parts, thereby repairing the fracture. When using argon arc welding, you need to be familiar with the appropriate arc parameters and operating skills to ensure the quality of welding.
Replace new tungsten wire: If the damage is too severe and cannot be repaired by the above methods, or the repair cost is too high, it is recommended to replace the new tungsten wire. When replacing, a new tungsten wire that matches the specifications and performance of the original tungsten wire should be selected to ensure the normal operation and use effect of the equipment.
- Preventive measures
In order to reduce the mechanical damage of the tungsten wire, the following preventive measures can be taken:
Strengthen equipment maintenance: Regularly inspect and maintain the equipment to ensure the normal operation and accuracy of the equipment. Avoid tungsten wire damage caused by equipment failure.
Optimize the operation process: Reasonably set process parameters such as wire drawing speed and heating temperature to reduce tungsten wire damage caused by improper operation.
Improve operating skills: Strengthen the training of operators to improve their operating skills and quality awareness. Avoid tungsten wire damage caused by operating errors.
