welding — Technique for joining metallic parts, usually through the application of heat. Discovered in the 1st millennium AD during attempts to manipulate iron into useful shapes, the technique produced a strong, tough blade. Welding traditionally involved … Universalium
Current source — Figure 1: An ideal current source, I, driving a resistor, R, and creating a voltage V A current source is an electrical or electronic device that delivers or absorbs electric current. A current source is the dual of a voltage source. The term… … Wikipedia
Welding power supply — A welding power supply is a device that provides an electric current to perform welding. Welding usually requires high current (over 80 amperes) and it can need above 12,000 amps in spot welding. Low current can also be used; welding two razor… … Wikipedia
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
Gas tungsten arc welding — TIG welding of a bronze sculpture Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG … Wikipedia
Shielded metal arc welding — (SMAW), also known as manual metal arc (MMA) welding, flux shielded arc welding … Wikipedia
Plasma 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 … Wikipedia
Orbital welding — is a specialised area of welding whereby the arc is rotated mechanically through 360° (180 degrees in double up welding) around a static workpiece, an object such as a pipe, in a continuous process. Contents 1 History 2 Equipment 3 Application … Wikipedia
Gas metal arc welding — RMD redirects here. RMD may also refer to IRA Required Minimum Distributions. Gas metal arc welding … Wikipedia
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
Electric 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… … Wikipedia
