The history of sticking the metals together is a very old technique with the most primitive examples of welding from the Bronze Age and the Iron Age in Europe and the Middle East counties. Welding is a creative skill that has a lot of scope to perform. A lot of unique and different energy resources are being used for welding.
A few sources of welding energy are a gas flame, an electric arc, a laser, an electron beam, friction, and ultrasound. Despite the fact that, welding can be done in many dissimilar situations, like open air, under water and in outer space welding in industries is of great use and is most often in almost all industrial process.
Even till today as technology and safety gears are advancing, welding stays as a dangerous and precautions process. Welders need to take a lot of safety measures to avoid burns, electric shock, eye damage, poisonous fumes, and overexposure to ultraviolet light and radiations.
Tungsten is one of the most uncommon metallic elements used in the manufacturing industry of TIG electrodes. These electrodes are mainly use due to their hardness and high temperature resistance it can give. Likewise, Tungsten has a very high melting point and hence more practical in welding processes.
Good arc stability for AC welding with balanced wave is provide by these electrodes when heated and AC sine wave with good arc stability is produced when pure tungsten is used is welding aluminum and magnesium specifically. Welding performance and arc quality is mainly depends on the type and shape of tungsten that is been used.
