Types of Welding

Can you name the types of welding?

HintMethod of Welding
Uses a graphite electrode to produce an electrical arc.
Uses a consumable coated electrode coated in flux.
Uses a continuous consumable wire electrode and a sheilding gas.
Uses a nonconsumable tungsten electrode. Filler metal is not always required.
Uses a continuously fed tubular electrode containing a flux, sometimes with a sheilding gas as well.
Uses a nonconsumable tungsten electrode, and a copper nozzle to constrict the arc and create a stream of ionized gas.
Uses a continuous wire-feed electrode. The weld is buried in a blanket of granules which melts and covers the weld area, protecting it from the atmosphere.
Uses two copper alloy electrodes to clamp the work and apply enough current to fuse the layers of metal. Mostly used for joining sheet metal.
HintMethod of Welding
Uses a beam of high velocity charged particles to melt the workpiece.
Uses a beam of coherent light as a heat source to melt and join two pieces of metal.
Uses a fuel gas and oxygen to provide heat to melt the workpiece, then filler metal is added manually to the weld puddle.
Uses a mixture of iron oxide and aluminum powders which is ignited. The resulting chemical reaction produces molten iron. Commonly used to join railroad tracks.
Uses high-frequency vibration to join tiny wires or thin sheets. Commonly used with plastics as well as metals.
Two very smooth parts are brought together in a vacuum, and fuse without heat when they touch each other. Pressure is applied to improve the contact area.
Two parts are spun at high speed and brought together. The heat generated causes the parts to fuse. Can also be performed by bringing a spinning probe into contact with the parts.
Uses an energetic chemical reaction to accelerate one material into another at high velocity. The impact creates enough pressure to pernanently join the two parts.
