Ultrasonic metal welding was discovered by chance in the 1930s. At the time, when the current spot welding electrode was added to the ultrasonic vibration test, it was found that the current could not be welded, and the ultrasonic metal cold welding technology was developed. Although ultrasonic welding was discovered earlier, the mechanism of action has not been clear so far. It is similar to fric...

  For a given set of weld parameters, variations in force control that result in applying too little force reduce compression of the mating surfaces, reduce the heat generation needed for plastic melt, and result in cold or weaker welds. Similarly, force variations that result in applying too much force can cause part joints or energy directors to deform, deflect or break and may not provide ...

  Development trend of ultrasonic welding technology   1. Improving welding productivity is an important driving force for the development of welding technology. There are two ways to improve productivity: firstly improve the welding deposition rate, such as three-wire submerged arc welding, the process parameters are 220A/33V and 1400A40V1100A45V respectively. The groove section is smal...

  The fixture material choice will also affect how the plastic material flows at the joint interface. A soft resilient type of material will create a different flow rate than a rigid metal nest. Different fixture materials will create various frictional reactions at the weld joint. An experienced ultrasonic tool maker can assist with choosing the appropriate fixture material. Most of the time...

  Many different types of materials have been used to build fixtures for ultrasonic assembly including plastics, stainless steel, tool steel, aluminum, cork, poured urethane and silicone rubber. All of these can play a role depending upon customer’s needs, but the most common fixtures include aluminum, steel and poured urethane. Poured urethane fixtures are frequently used for supporting rigi...

  The use of CAD/CAM technology has greatly improved the manufacturing of contoured fixtures to support the part during ultrasonic assembly. Exact mirror replicas of the part can be created to provide excellent support to the part. Due to complex contours seen on many parts, it is recommended that the horn and fixture be purchased as a set, so proper alignment is achieved between the two. The...
