The probe configuration in ultrasonic welding typically consists of a converter, a booster, and a horn. The converter is a piezoelectric transducer that converts electrical[…]

In ultrasonic welding, there are typically four phases of welding: The parameters such as amplitude, pressure, and time can be varied during each phase to[…]

Bad part limits in ultrasonic welding refer to the set of conditions or characteristics of a welded part that deem it unacceptable or unsatisfactory for[…]

Welding by position or absolute distance in ultrasonic welding refers to controlling the weld process based on the actual position or distance between the horn[…]

Welding by distance is a method of controlling the ultrasonic welding process based on the distance traveled by the ultrasonic horn during the welding cycle.[…]

Welding by energy is a method of controlling the ultrasonic welding process based on the amount of energy delivered to the joint, rather than the[…]

Welding by time is a method of controlling the duration of ultrasonic energy applied during the welding process. In this method, the ultrasonic generator is[…]

A shear joint is a type of joint commonly used in ultrasonic welding that involves joining two materials in a parallel configuration. In this joint,[…]

Mold release agents are typically used to facilitate the release of plastic parts from the mold during the injection molding process. However, these agents can[…]

Hygroscopicity is the ability of a material to absorb moisture from the environment. In ultrasonic welding, the presence of moisture can have a significant impact[…]
