When was ultrasonic welding invented?

In 1965, Robert Soloff, an American lab manager, accidentally made the discovery of ultrasonic welding when he unknowingly moved an ultrasonic probe close to a plastic dispenser and the joint of the dispenser welded together.

What is an ultrasonic welder used for?

Ultrasonic welding is an industrial process whereby high-frequency ultrasonic acoustic vibrations are locally applied to workpieces being held together under pressure to create a solid-state weld. It is commonly used for plastics and metals, and especially for joining dissimilar materials.

Which type of welding is ultrasonic welding?

Ultrasonic welding (USW) is a solid-state welding process that produces a weld by local application of high-frequency vibratory energy while the work pieces are held together under pressure. A sound metallurgical bond is produced without melting the base material.

What is ultrasonic metal welding?

Ultrasonic metal welding is a solid-state bonding process in which ultrasonic vibrations create friction-like motion between two surfaces, causing deformation and shearing of asperities to bring metal-to-metal contact and bonding.

What is the basic principle of ultrasonic welding?

The process relies on high-frequency (ultrasonic) vibrations being generated and applied to the parts via a horn. Welding occurs as the vibrations are absorbed in the interface between the two parts, generating friction and causing the plastic to melt.

Is ultrasonic welding waterproof?

Sonikel Ultrasonics, designs and manufactures Ultrasonic Welding Machine for waterproof welding of ABS and Polycarbonate. Supporting by Industry 4.0 theory, ultrasonic welder designed by Sonikel, lets mass production and automation. There will be no need to use any chemicals for sealing plastic parts to each other.

What is the main function of booster is ultrasonic welding?

The booster section of the welding stack serves two purposes, primarily to amplify the mechanical vibrations produced at the tip of the transducer and transfer them to the welding horn. Its secondary purpose is to provide a location for mounting the stack on the welding press.

How much does ultrasonic welding cost?

Ultrasonic welders cost anywhere from $18,000 to $45,000, depending on power capacity and bells and whistles, such as statistical process control packages. A basic 20-kilohertz, 2.5- to 3.5-kilowatt ultrasonic metal welding system can be acquired for around $30,000.

What is the main function of booster in ultrasonic welding?

What are some advantages of ultrasonic welding?

Ultrasonic welding offers some key advantages over other forms of welding:

  • It saves time. It is much faster than traditional welding methods, as virtually no time is needed for drying or curing.
  • It saves production costs.
  • It produces a high-quality bond and a clean, tight seal.

Can ultrasonic welding damage components?

Ultrasonic welders deliver high frequency vibrations to join two materials together. The welding tip or horn typically vibrates at a rate of 20,000 or 40,000 hertz and that can cause damage to certain electronic components.

What is the principle of ultrasonic welding?

Which is the most advanced ultrasonic welding system?

Dukane’s Ultrasonic Welders set the industry benchmark when it comes to quality, standard and precision in plastic welding. iQ Series line of ultrasonic welders are the most advanced systems in the industry and presented the first and the only Servo driven ultrasonic welder with Melt-Match® technology.

What happens when you use ultrasonic welding on plastic?

When welding plastics, the interface of the two parts is specially designed to concentrate the melting process. One of the materials usually has a spiked or rounded energy director which contacts the second plastic part. The ultrasonic energy melts the point contact between the parts, creating a joint.

What was the first welding company in America?

Two German welders came to the U.S. and formed Siemund-Wienzell Electric Welding Co. and patented a metal arc welding method. Another German formed company, Enderlein Electric Welding Co. also started up. This was the beginning of the arc welding industry in the U.S.

Can a sonotrode be used as an ultrasonic welder?

Without major modification or rewiring, it can be quickly and simply supplemented with a built-in multi-finger switch. The handheld ultrasonic welder and sonotrode are kept safe in the HSG MobileCase. This provides optimal storage for both the generator and connector cable.
