welding — 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 … Dictionary of automotive terms
Plastics 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… … Wikipedia
Welding — 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… … Wikipedia
Welding 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 … Wikipedia
Ultrasonic 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… … Wikipedia
Plastic 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 … Wikipedia
Friction 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… … Wikipedia
American 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… … Wikipedia
Gas tungsten arc welding — TIG welding of a bronze sculpture Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG … Wikipedia
Laser beam welding — (LBW) is a welding technique used to join multiple pieces of metal through the use of a laser. The beam provides a concentrated heat source, allowing for narrow, deep welds and high welding rates. The process is frequently used in high volume… … Wikipedia
