With speed welding, the plastic welder, similar to a soldering iron in appearance and wattage, is fitted with a feed tube for the plastic weld rod. The speed tip heats the rod and the substrate, while at the same time it presses the molten weld rod into position. A bead of softened plastic is laid into the joint, and the parts and weld rod fuse.
Heat is generated from friction between the two parts when rotating and subjected to a load normal to the weld joint. This frictional heat causes the plastic to melt and a bond to be created. [1] Due to this process's high speed, and repeatability it is favored in high production environments.
Higher weld travel speed can be obtained using a speed tip. Localization of high temperature gas on the weld surface allows for thermoplastics to heat up faster and flow easier, resulting in an increase in capable welding speed. [2] Too fast of a welding speed can stretch the weld rod, unevenly filling the joint and compromising the overall ...
The speed tip heats the rod and the substrate, while at the same time it presses the molten weld rod into position. A bead of softened plastic is laid into the joint and the parts and weld rod fuse. With polypropylene, the melted welding rod must be "mixed" with the semi-melted base material being fabricated or repaired. A speed tip "gun" is ...
Ultrasonic welding of thin metallic foils. The sonotrode is rotated along the weld seam. Ultrasonic welding is an industrial process whereby high-frequency ultrasonic acoustic vibrations are locally applied to work pieces being held together under pressure to create a solid-state weld.
Scan welding is a type of continuous ultrasonic welding in which case large plates or sheets can be welded. [3] In scan welding, a part is secured on a stationary table and the horn moves across the part creating a weld joint. A combination of stationary horn and mobile table can also be employed. The horn has round edges as in case with ...
