[16] Another example is the packaging of ammunition and propellants. Ultrasonic welding is mainly suitable for copper and aluminum connections. Fortunately, the risk of this kind of damage occurring is lowered when completed by experienced professionals. Telsonic takes an innovative path to new solutions in Ultrasonic Metal Welding. This container weld must be able to withstand high pressure and stress and must be airtight to contain the butane. Ultrasonic welding is well suited for a large number of automotive components, where high part counts and appropriate strength are required. One of the areas in which ultrasonic welding is most used and where new research and experimentation is centered is microcircuits. Whether two items can be ultrasonically welded is determined by their thickness. For example, if over-welding occurs, then the concentration of plastic in the weld zone may be too low and cause the seal to break. [8] One example is a butane lighter. In ultrasonic welding, ultrasonic vibrations create a friction-like relative motion between two surfaces that are held together under pressure. A controller controlling the movement of the press and the delivery of the ultrasonic energy. Ultrasonic welding machines require routine maintenance and inspection. Ultrasonic metal welding developed during the 1950s through the 1990s as the electronics used in the equipment became more sophisticated and computers could control the process. Some other food items sealed using ultrasonic welding include candy bar wrappers, frozen food packages and beverage containers. It is accomplished by converting high-frequency electrical energy into high-frequency mechanical motion. This is the main obstacle in the welding of metals. Operators should be informed of government agency regulations for the ultrasonic welding equipment and these regulations should be enforced.[18]. Packaging is an application where ultrasonic welding is often used. It offers many advantages, including process reliability and repeatability, lower energy usage than other joining techniques, material savings (because there is no need for consumables, such as glue or mechanical fasteners), and labor savings. Semiconductor devices, transistors and diodes are often connected by thin aluminum and gold wires using ultrasonic welding. He unintentionally moved the probe close to a plastic tape dispenser and the halves of the dispenser welded together. When planning welds between semi-crystalline plastic work pieces, it is important to remember that the welding behavior of these plastics differs considerably from that of amorphous plastics. The goal was to understand the main mechanisms involved in the welding process and how they affect the performance of the joint. Our High Powered systems and unique Torsional Welding SONIQTWIST®, expand the metal welding spectrum, facilitating the joining of a wide range of materials, sizes and geometries previously outside the capability of Ultrasonic Metal Welding. The understanding of ultrasonic welding has increased with research and testing. (Note: Common frequencies used in ultrasonic welding of thermoplastics are 15 kHz, 20 kHz, 30 kHz, 35 kHz, 40 kHz and 70 kHz). but it can be used on parts as large as a small automotive instrument cluster. The low thermal impact on the materials involved enables a greater number of materials to be welded together. When sealing hazardous materials, safety is a primary concern. These include many parts made of thermoplastic materials for interior and exterior applications, and engine compartments, but also of nonferrous metals for cable harnesses and lithium-ion batteries: Shielding this radiating sound can be done using an acoustic enclosure.
