What is Ultrasonic Spot Welding?
It is a process where materials are joined at certain points with no specific joint designed on its interface. It is used in micro-joining of metal or plastic products to multiple parts, such as metal sheets of complex forms. This is also used in soldering, metal welding, hermetic sealing, and thermoplastic joining.
This technology was integrated into the manufacturing industry in making joints of alloy and plastics. In short, this is a solid joining technique.
Advantages of Using Ultrasonic Spot Welding
Using this technology in the manufacturing industry has many advantages. Aside from speed, it includes machine durability and cost-effectiveness. It is ideal for melding components because it creates clean and reliable welds.
It is widely applied in the industries of electronics, aerospace, metal furniture, automotive, and medical equipment. This includes blister packs that are tamper-proof and vacuum-sealed. It may be automated by integrating it with robotics manipulation technology. This is quite common in high volume assembly lines.
How Strong is Ultrasonic Spot Welding?
This technology creates joints that are stronger compared to other spot welding techniques. Weld strength is critical because of the costly materials used in the manufacturing industries.
In a study on ultrasonic welding, defect-free sturdy spot welds were accomplished. The micro-hardness of the spot weld between similar and dissimilar joints was near-constant. The tensile lap shear failure load increased with increasing welding energy.
The quality of spot welds is therefore critical in manufacturing defect-free products. This is especially applicable in the aerospace and automotive industry. Structural durability and integrity are important.
