What are the reasons for tungsten rod bending after burning out?
1. Thermal stress: When a tungsten rod is heated to high temperatures, it is subject to thermal stress, which may cause it to bend or warp. This can happen if the rod is not properly supported or is subjected to rapid temperature changes.
2. Material fatigue: Tungsten rods will experience material fatigue after being used at high temperatures for a long time. This can cause the material to weaken, making it easier to bend or warp.
3. Insufficient cooling: If the tungsten rod is not properly cooled after use, heat may be retained and continue to deform during the cooling process, resulting in bending.
4. Mechanical damage: If the tungsten rod is subjected to mechanical stress or impact during use, micro-cracks or other structural damage may occur, resulting in bending after burning.
What are the precautions for using tungsten rods?
1. Choose the appropriate tungsten rod
Choose appropriate materials and specifications when using tungsten rods. Different application scenarios require the use of different specifications and lengths of tungsten rods.
2. Control heating temperature
When heating tungsten rods, it is important to control the temperature and pay attention to the heating time to avoid excessively high temperatures or long heating times.
3. Avoid excessive stretching
When using tungsten rods, excessive stretching should be avoided, and changing the welding method or other processing techniques can be considered.
