plastics welding
1plastics welding — A uniting of thermoplastic, i.e., non setting plastics of similar or different type using heat and pressure and with or without the addition of plastic of a similar kind (filler material). The welding proceeds within the temperature range of… …
2welding — Art of fastening metals (or plastic) together by means of interfusing them. They are heated to a suitable temperature. In some cases pressure is used to bond them together. In other cases a filler material (solder) is used to join them. Among the …
3Plastics engineering — encompasses the processing, design, development, and manufacture of plastics products. A plastic is a polymeric material that is in a semi liquid state, having the property of plasticity and exhibiting flow. The nature of plastic materials poses… …
4Welding — is a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld puddle ) that cools to… …
5Welding joints — are formed by welding two or more workpieces, made of metals or plastics, according to a particular geometry. The most common types are butt and lap joints; there are various lesser used welding joints including flange and corner joints. Contents …
6Ultrasonic welding — is an industrial whereby high frequency ultrasonic acoustic vibrations are locally applied to workpieces being held together under pressure to create a solid state weld. It is commonly used for plastics, and especially for joining dissimilar… …
7Plastic welding — is the process of welding plastic parts together. There are several techniques:Hot gas weldingThis is a plastic welding technique which is analogous to gas welding of metals, though the specific techniques are different. A specially designed heat …
8Friction welding — (FW) is a class of solid state welding processes that generates heat through mechanical friction between a moving workpiece and a stationary component, with the addition of a lateral force called upset to plastically displace and fuse the… …
9American Welding Society — The American Welding Society (AWS) is a nonprofit organization dedicated to advancing the science, technology, and application of welding and allied joining and cutting processes, including brazing, soldering, and thermal spraying. The… …
10Gas tungsten arc welding — TIG welding of a bronze sculpture Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG …
