The welding advantages and welding structure of handheld ultrasonic welding machine
Advantages of ultrasonic metal welding:
1. The welding material does not melt and is not fragile metal;
2. Good electrical conductivity after welding, very low or almost zero resistivity;
3. Low requirement for welding metal surface, can be welded by oxidation or electroplating;
4. Short welding time, without any flux, gas, solder;
5. No spark welding, environmental protection and safety.
ultrasonic plastic welding advantages:
1. Fast welding speed, high welding strength, good sealing;
2. Replace the traditional welding/bonding process, low cost, clean, pollution-free and no damage to the workpiece;
3. The welding process is stable. All welding parameters can be tracked and monitored by the software system.
In the selection process of ultrasonic welding, according to the following factors to choose the appropriate welding structure:
1. Materials used;
2. Product shape and size;
3. Other requirements (watertightness, etc.).
The welding structure design follows the following principles:
1. Small initial contact between upper and lower parts;
2. The welding product can be self-calibrated;
3. The contact surface of welding head is directly above the welding area.
The structure design of ultrasonic welding is mainly divided into two categories:
1. The fuse
1) Improve welding strength;
2) Reduce flying debris;
3) Reduce the welding time;
4) Reduce the amplitude required for welding to a certain extent.
2. Shear welding
1) High welding strength, can achieve water tightness;
2) Can be used for semi-crystal plastic welding;
3) For semi-crystal plastics to avoid the phenomenon of early melting
