To reduce the damage of tungsten wire caused by thermal stress, we can start from the following aspects:
- Optimize tungsten wire materials and design
Choose high-quality tungsten wire:
Choose tungsten wire with high purity and uniform grain structure to reduce the influence of impurities and grain boundaries on thermal stress.
If the tungsten wire contains more impurities or uneven grain structure, the risk of thermal stress concentration and damage will increase.
Optimize structural design:
By improving the structural design of tungsten wire, such as adopting a reasonable wiring method, the uneven distribution of current in the tungsten wire can be reduced, thereby reducing thermal stress.
Use heat dissipation devices, such as heat sinks, cooling fans, etc., to dissipate the heat generated by the tungsten wire in time to reduce the accumulation of thermal stress.
- Control the working environment and conditions
Keep clean and dry:
Keep the working environment of the tungsten wire clean and dry to avoid the influence of dust and moisture on the tungsten wire.
Dust and moisture may increase the thermal resistance of the surface of the tungsten wire and aggravate the generation of thermal stress.
Reasonably control temperature:
Avoid tungsten wire working at high temperature for a long time to reduce the accumulation of thermal stress.
Use equipment such as temperature controllers to control the working temperature of tungsten wire within a reasonable range to avoid adverse effects of excessively high or low temperatures on tungsten wire.
Stabilize current and voltage:
Unstable current or Voltage fluctuations may increase the thermal stress of tungsten wire and cause damage.
Use equipment such as current stabilizers and voltage stabilizers to ensure the stability of current and voltage and reduce the thermal stress of tungsten wire.
- Strengthen maintenance and monitoring
Regular inspection and maintenance:
Regularly maintain and maintain the tungsten wire to check whether it is damaged or aged.
For tungsten wire with problems, it should be replaced or repaired in time to avoid further damage caused by thermal stress.
Use thermal stress monitoring equipment:
Install thermal stress monitoring equipment near the tungsten wire to monitor the thermal stress state of the tungsten wire in real time.
Once abnormal thermal stress is found, take measures to adjust it immediately to avoid damage.
- Use stress relief methods
Heat treatment:
Annealing and other heat treatment operations on tungsten wire can eliminate its internal stress and improve its resistance to thermal stress.
During the annealing process, the grains inside the metal will be rearranged and the stress will gradually be released.
Mechanical treatment:
Use rolling, vibration stress relief and other methods to mechanically treat the tungsten wire to eliminate its internal stress.
These methods are suitable for tungsten wire parts with simple shapes and easy operation.
