Welding

English: 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 that cools to become a strong joint, but sometimes pressure is used in conjunction with heat, or by itself, to produce the weld. This is in contrast with soldering and brazing, which involve melting a lower-melting point material between the workpieces to form a bond between them. Many different energy sources can be used for welding, including oxy-acetylene gas, an electric arc, a laser, an electron beam, friction, and ultrasound. While often an industrial process, welding can be done in many different environments, including open air, underwater and in space. Regardless of location, however, welding remains dangerous, and precautions must be taken to avoid burns, electric shock, poisonous fumes, and overexposure to ultraviolet light.
Español: La soldadura es la unión de dos materiales (generalmente metales) a través de un proceso de fusión en el cual las piezas son soldadas derritiendo ambas y agregando metal o plástico derretido para conseguir una "pileta" (punto de soldadura) que, al enfriarse, forma una unión fuerte.
日本語: 溶接は金属材料を加熱して溶かす事によって接続する手法である。加熱方法としては電弧やジュール熱やレーザー等を使用する。
