Why do welded parts need to design the welding wire of the ultrasonic welding machine?

The welding wire of the Ultrasonic Welding Machine is referred to as the fuse line, and it is also called the fusing wire column, ultrasonic wire and so on. An ultrasonic welding wire is a triangular column raised on the welding interface of a plastic part, and the sharper the tip, the better. The role of the ultrasonic welding machine weld wire is to gather the vibration energy at the tip of the triangle, and then the accumulated heat will form a uniform plastic melt flow throughout the welding interface.

The ultrasonic welding line facilitates the fusion of two plastic parts and improves the strength of the welding. If virtual welding occurs during product welding using ultrasonic welding wire, there will be a gap between the two plastic parts, and it is easy to find defects in virtual welding. This avoids the occurrence of ultrasonic virtual welding. If virtual welding occurs during ultrasonic welding of products without ultrasonic welding wire, it is difficult to distinguish by appearance.

Ultrasonic plastic welding is a must to design ultrasonic welding wire

In short, ultrasonic plastic welding must be designed ultrasonic welding wire, and the design of ultrasonic welding wire is basically designed according to the welding requirements of the welded part, so there is no unified design standard.
