• Arc 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.… …   Wikipedia

• Carbon arc welding — (CAW) is a process which produces coalescence of metals by heating them with an arc between a nonconsumable carbon (graphite) electrode and the work piece. It was the first arc welding process ever developed but is not used for many applications… …   Wikipedia

• atomic arc welding — Welding using heat created by hydrogen atoms, created by an electric arc recombining to form hydrogen molecules. The heat is used to weld delicate joints, and the hydrogen forms a shield over the weld …   Dictionary of automotive terms

• 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

• Hydrogen embrittlement — (or hydrogen grooving) is the process by which various metals, most importantly high strength steel, become brittle and crack following exposure to hydrogen. Hydrogen cracking can pose an engineering problem especially in the context of 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 — the process of joining together two pieces of metal so that bonding accompanied by appreciable interatomic penetration takes place at their original boundary surfaces. The boundaries more or less disappear at the weld, and integrating crystals… …   Mechanics glossary

• Atomic 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… …   Wikipedia
