Three Types Of PVC Welding

Ultrasonic PVC Welding is an industrial technique whereby two pieces of plastic or metal are joined together seamlessly through high-frequency acoustic vibrations. One component to be welded is placed upon a fixed anvil, with the second component being placed on top. An extension ("horn") connected to a transducer is lowered down onto the top component, and a very rapid (~20,000 KHz), low-amplitude acoustic vibration is applied to a small welding zone. The acoustic energy is converted into heat energy by friction, and the parts are welded together in less than a second.

Plastic welding is a method of fabrication used to fuse plastic parts together. The process works by heating parts of each piece until they soften or liquefy. When the plastics cool, a chemical bond is formed between them that fuses the pieces together. A thermoplastic welding rod is commonly used to act as glue between the two pieces.

Several methods of plastic welding are employed for different purposes. They vary according to the type of welding equipment and welding supplies used. The base material the plastic component is made of also affects the method used for plastic welding. Thermoplastics are generally preferred because of their ability to be repeatedly melted and re-solidified.

Orbital welding is Automatic Tunguston inert gas welding. It eliminates chances of manual errors in welding. It produces identical welds for hundred of times hence accuracy in welding.

Orbital welding was first used in the 1960`s when the aerospace industry recognized the need for a superior joining technique for aerospace hydraulic lines. A mechanism was developed in which Radio Frequency Welding Machine the arc from a tungsten electrode was rotated around the tubing weld joint. The arc welding current was regulated with a control system thus automating the entire process. The result was a more precision and reliable method than the manual welding method it replaced.
