Ultrasonic Punching Welder for Auto Wheel Arch Welding
Ultrasound is not a source of radiation and generally harmless.We all know that when an object vibrates it makes a sound, and the number of vibrations per second is called the frequency of sound, and it's in Hertz. We human ears can hear sound waves of 20 to 20,000 Hertz. When the vibration frequency of sound waves is greater than 20,000 Hertz or less than 20 Hertz, we cannot hear them. Ultrasonic frequencies commonly used in medical diagnosis range from 1 to 5 MHZ. Ultrasonic wave has good direction, strong penetrating ability, easy to obtain concentrated sound energy, long distance in water and other characteristics. It can be used for distance measurement, speed measurement, cleaning, welding, gravel, etc.
1. The loose connecting screw between the ultrasonic horn and transducer will lead to the high electric current. The usual way to remove it from a machine that has been in use for some time is to tighten it with a special wrench for ultrasonic die head to see if the die head has not been locked.
2. Ultrasonic mould or horn is damaged broken, it usually appears on the ultrasonic equipment that has been used too long or for a long time, the elimination method is to check whether there is crack in the appearance of the die head, or install it on other ultrasonic systems to check.
3. Replace the ultrasonic transducer vibrator or the ultrasonic horn, if you replaced these two parts lead to high current, such situation is normal, as long as through ultrasonic frequency adjustment can solve this problem.
