• 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

• 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

• Surface engineering — is the sub discipline of materials science which deals with the surface of solid matter. It has applications to chemistry, mechanical engineering, and electrical engineering (particularly in relation to semiconductor manufacturing).Solids are… …   Wikipedia

• Surface grinding — is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or non metallic substance from a workpiece, making a… …   Wikipedia

• Welding defect — A welding defect is any flaw that compromises the usefulness of the finished weldment. According to the American Society of Mechanical Engineers (ASME) welding defect causes are broken down into the following percentages: 41% poor process… …   Wikipedia

• welding — Technique for joining metallic parts, usually through the application of heat. Discovered in the 1st millennium AD during attempts to manipulate iron into useful shapes, the technique produced a strong, tough blade. Welding traditionally involved …   Universalium

• Friction stir welding — (FSW) is a solid state joining process (meaning the metal is not melted during the process) and is used for applications where the original metal characteristics must remain unchanged as far as possible. This process is primarily used on aluminum …   Wikipedia

• Resistance welding — refers to a group of welding processes that produce coalescence of faying surfaces where heat to form the weld is generated by the resistance of the welding current through the workpieces. Some factors influencing heat or welding temperatures are …   Wikipedia

• Laser-hybrid welding — is a type of welding process that combines the principles of laser beam welding and arc welding. Introduction The combination of laser light and an electrical arc into an amalgamated welding process has beenknown since the 1970 s, but has only… …   Wikipedia
