gas-shielded welding
11Welding 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… …
12Arc welding — uses a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point. They can use either direct (DC) or alternating (AC) current, and consumable or non consumable electrodes.… …
13Shielding gas — Shielding gases are inert or semi inert gases that are commonly used in several welding processes, most notably gas metal arc welding and gas tungsten arc welding. Their purpose is to protect the weld area from atmospheric gases, such as oxygen,… …
14Oxy-fuel welding and cutting — Oxyacetylene redirects here. For the song, see Cubanate. Side of metal, cut by oxygen propane cutting torch …
15Flux-cored arc welding — (FCAW) is a semi automatic or automatic arc welding process. FCAW requires a continuously fed consumable tubular electrode containing a flux and a constant voltage or, less commonly, a constant electric current welding power supply. An externally …
16Wolfram-Inert-Gas — Stoßarten: 1. Stumpfstoß, z. B. für I Naht 2. Stoß für V Naht 3. Überlappungsstoß, z. B. für Punktnaht) 4. T Stoß für Kehlnaht …
17Electric resistance welding — (ERW) refers to a group of welding processes such as spot and seam welding that produce coalescence of faying surfaces where heat to form the weld is generated by the electical reistance of material vs the time and the force used to hold the… …
18Atomic hydrogen welding — (AHW) is an arc welding process that uses an arc between two metal tungsten electrodes in a shielding atmosphere of hydrogen. The process was invented by Irving Langmuir in the course of his studies of atomic hydrogen. The electric arc… …
19MIG welding — An arc welding method in which the electric current is provided by the filler metal wire which is cooled and shielded from the access of air by a stream of chemically inert gas, thus preventing oxidation of the joint. Compare TIG welding …
20сварка в защитных газах — [gas shielded welding] дуговая сварка, при которой в зону соединения подаются защитные газы для предотвращения воздействия воздуха на металл шва. Газовая защита способствует также устойчивому горению дуги, улучшению условий формирования шва,… …
