Welding The most popular processes are shielded metal arc welding (SMAW), gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW). • All of these methods employ an electric power supply to create an arc which melts the base metal(s) to form a molten pool. The filler wire is then either added automatically (GMAW) or manually (SMAW & GTAW) and the molten pool is allowed to cool. •

Welding Process In the welding process, metal is melted to bridge the parts to be joined, so that on solidification of the weld metal the parts become united. Welding is often done with pressure, sometimes in conjunction with heat, to produce the weld. Different welding techniques include: Gas metal arc welding. Submerged arc welding. Flux-cored arc welding.

Legalâ¢Info Welding is the action of joining two pieces of metal together by the use of heat; the heat melts and liquifies the metal (referred to as coalescence) so they can be joined together. In order to melt part of a large piece of metal, you need to apply a large amount of either pressure or heat to it.

Ultimate Guide To The Various Types Of Welding Gas Metal Arc Welding. The process of Gas Metal Arc Welding (GMAW), created in the 1940’s, is another automatic welding process. This method consists of the use of a welding gun which automatically feeds the weld metal through the gun for use. The weld gun also automatically distributes a protective gas as a shield from the natural elements. This process saves a lot of time and is best for a large quantity of welding work.

TIG Welding TIG Welding. TIG Welding, also known as Gas Tungsten Arc Welding (GTAW), is a process that joins metals by heating them with an arc between a tungsten electrode (non-consumable) and the work piece.The process is used with a shielding gas and may also be used with or without the addition of filler metal.The primary variables in TIG Welding are arc voltage (arc length), welding current, travel speed and shielding gas composition. The amount of energy the arc produces is proportional to the current and the voltage.IG Welding. TIG Welding, also known as Gas Tungsten Arc Welding (GTAW), is a process that joins metals by heating them with an arc between a tungsten electrode (non-consumable) and the work piece.

Resistance Welding Resistance welding uses the application of electric current and mechanical pressure to create a weld between two pieces of metal. Weld electrodes conduct the electric current to the two pieces of metal as they are forged together. The welding cycle must first develop sufficient heat to raise a small volume of metal to the molten state. This metal then cools while under pressure until it has adequate strength to hold the parts together.

Orthographic projection The orthographic projection has been known since antiquity, with its cartographic uses being well documented. Hipparchus used the projection in the 2nd century BC to determine the places of star-rise and star-set.n computer graphics, one of the most common matrices used for orthographic projection can be defined by a 6-tuple, (left, right, bottom, top, near, far), which defines the clipping planes. These planes form a box with the minimum corner at (left, bottom, - near) and the maximum corner at (right, top, - far).
