21Electron beam welding — (EBW) is a fusion welding process in which a beam of high velocity electrons is applied to the materials being joined. The workpieces melt as the kinetic energy of the electrons is transformed into heat upon impact, and the filler metal, if used …
22Radiographic testing — (RT), or industrial radiography, is a nondestructive testing (NDT) method of inspecting materials for hidden flaws by using the ability of short wavelength electromagnetic radiation (high energy photons) to penetrate various materials.Either an X …
23Electroslag welding — (ESW) is a highly productive, single pass welding process for thick (greater than 25mm up to about 300mm) materials in a vertical or close to vertical position. (ESW) is similar to electrogas welding, but the main difference is the arc starts in… …
24толщина — 3.1 толщина (thickness) d: Линейный размер, измеряемый перпендикулярно к лицевым граням изделия. Источник: ГОСТ Р ЕН 823 2008: Изделия теплоизоляционные, применяемые в строительстве. Методы измерения толщины 3.3 тол …

25Welding — 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… …
26Shielded metal arc welding — (SMAW), also known as manual metal arc (MMA) welding, flux shielded arc welding …
27Plasma arc welding — (PAW) is an arc welding process similar to gas tungsten arc welding (GTAW). The electric arc is formed between an electrode (which is usually but not always made of sintered tungsten) and the workpiece. The key difference from GTAW is that in PAW …
28Twin carbon arc welding — Unlike single carbon arc welding, in twin carbon arc welding the arc is maintained between two carbon electrodes held in a special holder. Current is switched on and by operating the mechanism of arc length adjustment the two electrodes are… …
29Welding 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… …
