Webmaterials can be ultrasonically welded without the use of solvents, heat or adhesives. Weldability of these materi-als depends on their melting tempera-tures, modulus of elasticity, impact resistance, coefficient of friction, and thermal conductivity. Generally, the more rigid the plastic, the easier it is to weld. Low modulus materials such as WebThis can be accomplished through the following steps: Check all parts before welding to ensure that they are clean and free of moisture. Recalibrate the base of the welder to ensure that it is level and makes full contact with the attachment before welding.
