Welding is an ordinary way to unite metals in the invention of many goods as well as automobiles, ships, trains, buildings, and bridges. Appreciation to innovative Welding technologies; welders work through much greater precision and stronger than in the 9th century, when forge welding was just technology to metals weld by blacksmiths beating jointly over hot coals. Welding technologies are developed in First World War, because many country looked into improved capable of welding ships and planes for the battle. Welding technology has enlarged and become more robust to perform by hand or automated machines. Welding equipment can be very portable to perform in a variety of environments, including under water.
At present, there are many familiar methods of welding consist of gas welding, arc welding, resistance welding, spot welding, electron beam welding, laser welding, and robot welding.
A method in gas oxygen is mixed to generate a high sufficient temperature at the torch to soften the edges of the metal being work with is call gas welding. Oxy-fuel welding basically requires two tanks, one of oxygen and another for the fuel being used.
Arc welding is creating an arc of electrical current among electrode and material being welded in order to attach the materials by melt together. Arc welding is used in industrial application due to low cost.
Resistance welding applies mechanical pressure and electric current to erect a weld between two metal pieces.
In spot welding, two electrodes are used to clamp metal sheets, applying pressure and passing current through them.
Electron beam welding is bombarding the equipment being welded with a grin of high velocity electrons collision of produces heat, melting the materials and weld together.
Laser beam welding uses laser to join multiple pieces of metal together via its concentrated heat source.
Robot welding is the most recent technology in welding computerization to perform all welding steps including the preparation and handling of materials. A human operator is still obligatory to organize materials and set welding machines. Robot welding is used in automobile assembly due to high volume production operations.
