Setting up process limits for ultrasonic welding involves establishing acceptable ranges for various welding parameters to ensure consistent and reliable weld quality. The following steps can be taken to set up process limits for ultrasonic welding: By setting up process limits for ultrasonic welding, manufacturers can ensure that the welding process produces high-quality welds that […]
The trigger method in ultrasonic welding is the way in which the ultrasonic weld is activated in an ultrasonic welding application. In an ultrasonic welding process, the horn will begin moving toward the fixtured part with the sonics turned off. The ultrasonics are triggered to turn on when the conditions of the trigger method are […]
Gating and degating are two important steps in the ultrasonic welding process, particularly when dealing with plastic parts. Gating refers to the process of creating a small opening, or “gate,” in the part that allows molten plastic to flow into the mold during the injection molding process. The gate is typically located at the edge […]
The wattage available in ultrasonic welding can vary depending on the specific application and equipment being used. Generally, ultrasonic welding machines can range from low wattage (around 500 watts) to high wattage (up to 6000 watts or more). Low wattage ultrasonic welders are typically used for smaller and less complex parts, while high wattage ultrasonic […]
In ultrasonic welding, a horn (also called a sonotrode) is used to apply high-frequency vibrations to the parts being welded. There are several types of horns used in ultrasonic welding, including: Tapered horns: These horns are used for general-purpose welding and are the most common type of horn used in ultrasonic welding. They have a […]
Determining which booster to use for an ultrasonic application requires some planning. You must amplitude requirement for the material you are welding.
When surface marking of a ultrasonically welded part is a concern, ultrasonic horns and nests can be plated to reduce defective parts.
The advantages of using ultrasonic welding are: 1) No consumables 2) Fast cycle times 3) Very accurate 4) Highly repeatable 5) Versatile equipment 6) Parts are easily recycled 7) Environmentally safe
As the frequency increases, vibration amplitude typically decreases. There are three advantages of using a higher frequency for Ultrasonic welding.
The industries listed below utilize ultrasonic welding in their manufacturing processes:
