Classification of Electric Welding Process


This electrical welding electrode webbed as additives.
Electric arc occurring between the tip electrode and also the base material can soften the tip of the electrode and also the used base material. Membrane electrode that conjointly burns can soften and turn out a gas that protects the tip of the crater welding electrodes, an electrical arc to the consequences of outdoor air. Liquid membrane electrode which can freeze the surface of the weld stop up that conjointly is a protection against external influences.
Electric arc temperature distinction depends on where the measurement purpose, eg, the electrode tip temperature of 3400 ° C, however the workpiece will reach temperatures of 4000 ° C.

Electric TIG welding
TIG welding (Tungsten Inert Gas = Noble Gas Tungsten) employing a tungsten electrode that isn't a new ingredient. electrical arc between tungsten electrode tip and also the base material could be a heat supply, for welding. Melting purpose of tungsten electrode is thus high up to 3410 ° C, in order that didn't participate within the event of melting electrical arc.
Electric rod equipped with a ceramic nozzle to safeguard the throwers protecting gas welding space from the skin at the time of welding.
Most of the added material is employed while not the membrane electrode is moved and dropped at the arc between tungsten electrode base material.
Argon used as a protecting gas, helium or a combination of each gases is that of usage reckoning on the sort of metal to be welded.
TIG welding rod is sometimes cooled with less water circulating.

TIG welding burner consists of:
Submerged electrical welding is sometimes automatic or semi-automatically using the flux powder for the protecting result of outdoor air. {an electrical|an electrical} arc between the electrode tip and also the base material within the pile in order that no ray flux welding out as usual on different electric welding. Welding operator doesn't got to use a glass eye protection (welding helmets).
At the time of welding, flux powder and frozen and can soften coating welded shut. Most of the flux powder that melts not be used once more when cleaning of the slag-slag welding.
Electrode that could be a coil-shaped wire vacum membrane (roll) is moved forward by some gears are rotated by an electrical motor ean be organized per the requirements of the welding speed.

Electric MIG welding
As with any electrical pedestal pad TIG, MIG power base pad is additionally heat generated by an electrical arc between 2 electrons and also the base material.
Electrode could be a wire coil that moves within the variety of rollers organized by the couple gear-driven electrical motor. Movement may be adjusted as necessary. The shaft equipped} with a nozzle weld metal to attach the protecting gas is supplied from the gas bottle through the gas hose.
CO2 gas is employed for welding delicate steel and steel. Argon or a combination of argon and helium for welding aluminum and chrome steel. MIG welding method is semi automatic get or automatic. Semi-automatic welding meant manually, whereas the automated welding is allotted entirely automatic.
The electrodes exit through the stalks at the side of a protecting gas.

Electric current
At this current, the electrons move along the conductor in one direction solely.
Direction of flow of alternating current is sinusoide wave intersecting the zero on the time interval 1/100 second for a machine with a frequency of fifty hertz (Hz). every cycle consisted of half-wave wave of positive and negative waves some middle. Alternating current may be converted into direct current by employing a flow modifier
