Gas tungsten arc welding

(Mühendislik) Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma

Manual metal arc

(Mühendislik) Shielded metal arc welding (SMAW), also known as manual metal arc (MMA) welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode coated in flux to lay the weld. An electric current, in the form of either alternating current or direct current from a welding power supply, is used to form an electric arc between the electrode and the metals to be joined. As the weld is laid, the flux coating of the electrode disintegrates, giving off vapors that serve as a shielding gas and providing a layer of slag, both of which protect the weld area from atmospheric contamination

Shielded metal arc welding

Submerged Arc Welding

(Mühendislik) Submerged Arc Welding (SAW) is a common arc welding process. It requires a continuously fed consumable solid or tubular (flux cored) electrode. The molten weld and the arc zone are protected from atmospheric contamination by being “submerged” under a blanket of granular fusible flux. When molten, the flux becomes conductive, and provides a current path between the electrode and the work

(Geometri) Determining the length of an irregular arc segment—also called rectification of a curve—was historically difficult. Although many methods were used for specific curves, the advent of calculus led to a general formula that provides closed-form solutions in some cases

gas metal arc welding

(Mühendislik) Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) welding or metal active gas (MAG) welding, is a semi-automatic or automatic arc welding process in which a continuous and consumable wire electrode and a shielding gas are fed through a welding gun. A constant voltage, direct current power source is most commonly used with GMAW, but constant current systems, as well as alternating current, can be used. There are four primary methods of metal transfer in GMAW, called globular, short-circuiting, spray, and pulsed-spray, each of which has distinct properties and corresponding advantages and limitations

the patron saint of France. As a young girl, she believed that she heard holy voices telling her to fight the English and force their army to leave France. Dressed as a man, she led a French army which defeated the English at Orléans, and became known as the ' Maid of Orléans'. Later she was made a prisoner, and a court found her guilty of being a witch (=a woman with evil magic powers) , and she was punished by being burned to death (1412-31)

Saint Joan of Arc

French Jeanne d'Arc born 1412, Domrémy, Bar, Fr. died May 30, 1431, Rouen; canonized May 16, 1920; feast day May 30 French military heroine. She was a peasant girl who from an early age believed she heard the voices of Sts. Michael, Catherine, and Margaret. When she was about 16, her voices began urging her to aid France's Dauphin (crown prince) and save France from the English attempt at conquest in the Hundred Years' War. Dressed in men's clothes, she visited the Dauphin and convinced him, his advisers, and the church authorities to support her. With her inspiring conviction, she rallied the French troops and raised the English siege of Orléans in 1429. She soon defeated the English again at Patay. The Dauphin was crowned king at Reims as Charles VII, with Joan beside him. Her siege of Paris was unsuccessful, and in 1430 she was captured by the Burgundians and sold to the English. Abandoned by Charles, she was turned over to the ecclesiastical court at Rouen, controlled by French clerics who supported the English, and tried for witchcraft and heresy (1431). She fiercely defended herself but finally recanted and was sentenced to life imprisonment; when she again asserted that she had been divinely inspired, she was burned at the stake. She was not canonized until 1920

arc furnace

Type of electric furnace in which heat is generated by an arc between carbon electrodes above the surface of the material (commonly a metal) being heated. William Siemens first demonstrated the arc furnace in 1879 at the Paris Exposition by melting iron in crucibles; horizontally placed carbon electrodes produced an electric arc above the container of metal. The first commercial arc furnace in the U.S. (1906) had a capacity of four tons (3.6 metric tons) and was equipped with two electrodes. Modern furnaces range in heat size from a few tons up to 400 tons (360 metric tons), and the arcs strike directly into the metal bath from vertically positioned, graphite electrodes to remelt scrap steel or refine briquettes of direct-reduced iron ore

Long, curved chain of oceanic islands associated with intense volcanic and seismic activity and mountain-building processes. Examples include the Aleutian-Alaska Arc and the Kuril-Kamchatka Arc. Most island arcs consist of two parallel rows of islands. The inner row is a string of volcanoes, and the outer row is made up of nonvolcanic islands. In the case of single arcs, many of the islands are volcanically active. An island arc typically has a landmass or a partially enclosed, unusually shallow sea on its concave side. Along the convex side there usually exists a long, narrow deep-sea trench
