Fixture and jig tooling in a vibration welder functions to hold and position parts precisely during the welding process using vibration. This tooling ensures proper alignment between the upper and lower parts, maintaining stability despite continuous linear vibration.

The design must be strong and rigid to withstand frictional forces and pressure during welding. With proper fixture and jig tooling, welding quality becomes more consistent and the risk of defects is reduced.

This tooling is commonly used in the automotive industry and for large or complex plastic products.
