The working principle of ultrasonic seam welding is the same as that of ultrasonic welding. But the main difference is that the former is a continuous weld through a disc-shaped welding head. For this, the roll seam welding head is installed on both sides. Welding heads made of hard steel are particularly wear-resistant and can be used for Cut&Seal; applications (simultaneous separation and welding), for example.

This technology has extremely high application flexibility: for example, for the circumferential welding of circular parts, the seam welding technology can be used to process various specifications with welding heads of different diameters on the welding device. In the textile industry, ultrasonic seam welding machines will be used instead of traditional sewing machines. The fabric made of thermoplastic synthetic fiber is no longer sewn with needles and threads, but is welded using ultrasonic waves, which is particularly beneficial to maintain the elasticity of the material.

More and more applications and products can be realized and improved using roll seam technology. Jiayuanda Technology has become a leader in the field of seam welding ultrasonic component system suppliers, especially in the textile industry. In addition, depending on the application, we will integrate the technology into non-standard equipment in different industries.
