What is the welding process?
Welding is just a fabrication process to join similar or dissimilar materials by the application of pressure and/or heat.
Welding operation has a big spread branch of classification, and which defines the kind of application, weldment and technology required to do the welding.
Gas-Tungsten Arc Welding (GTAW)
GTAW is a process in which an arc has been established between a non-consumable tungsten electrode and the metals by heating the metals and results in the melting and joining of the metals.
The tungsten electrode holding torch which is in connection with a shielding gas cylinder and one terminal of the power source is usually in contact with a water-cooled copper tube which is connected to the welding cable from the terminal. This allows the welding current to enter the electrode and the electrode to be cooled to prevent overheating.
The shielding gas goes through the torch body and is directed by a nozzle toward the welding pool to protect it from the air. Comparatively, GTAW is better than SMAW regarding the protection from air because an inert gas such as argon or helium is usually used. For this reason, GTAW is also called tungsten–inert gas (TIG) welding. When a filler rod is needed, for joining thicker materials, it can be fed either manually or automatically into the arc.
Shielded Metal Arc Welding (SMAW)
SMAW is a process in which an arc has been established between a sticklike covered electrode and the metals by heating the metals and results the melting and joining of the metals. It is often called stick welding.
The terminal of power source is connected with electrode holder by one cable and the other cable to the metal workpiece. The covered electrode core, the core wire, conducts the electric current to the arc and provides filler metal for the joint. The arc generates heat and causes both the core wire and the flux covering the electrode tip to melt off like-as droplets. The molten metal collects in the weld pool and solidifies into the weld metal. The molten flux, on the other hand, floats on the surface and solidifies into a slag layer at the top of the weld metal.
Gas – Metal Arc Welding (GMAW)
GMAW is a process in which an arc has been established between a continuously fed filler wire electrode and the metals by heating the metals and results the melting and joining of the metals.
By the usage of inert gases such as argon and helium, obtains the shielding of the arc and the molten weld pool, and this is why GMAW is also called the metal–inert gas (MIG) welding process. Since non-inert gases, particularly CO2, are also used, GMAW seems a more appropriate name.
This is the most widely used arc welding process for aluminum alloys. Unlike GTAW, Direct Current Electrode Positive (DCEP) is used in GMAW. A stable arc, smooth metal transfer with low spatter loss and good weld penetration can be obtained. With DCEN or AC, however, metal transfer is erratic.
Flux - Core Arc Welding (FCAW)
FCAW is similar to GMAW, however, the wire electrode is flux cored, i.e., the electrode is a metal tube with flux wrapped inside. The flux functions are similar to those of the electrode covering in SMAW, including protecting the molten metal from air.
Submerged Arc Welding (SAW)
SAW is a process in which an arc has been established between a consumable wire electrode and the metals, with the arc being shielded by a molten slag and granular flux and by heating them resulting the melting and joining of the metals.
This process is quite different from general arc welding because the generated arc is not visible as it got submerged in the molten slag and the supply of the slag happens through a kind of hopper which will travel along with the torch. No additional shielding is required as the arc has already been submerged in slag and protected from the air.
Laser Beam Welding (LBW)
LBW is a process in which laser beam generates the heat that results the melting and joining of metals. The laser beam can be produced either by a solid-state laser or a gas laser. In either case, the laser beam can be concentrated and travelled by optical means to achieve high power densities. In a solid-state laser, single crystal is doped with small concentrations of transition elements.
In a CO2 or gas laser, a gas mixture of CO2, N2 and He is continuously triggered by electrodes connected to the power supply and lases in a continuous way. Generally, higher power can be achieved by a CO2 laser compared to a solid-state laser.
