Co2 Welding Principle ~ Electric arc between the electrode and work piece closes the electric circuit. A constant voltage direct current power source is most commonly us. The CO 2 welding process popularized by Lyubavskii and Novoshilov in 1953 a first choice for welding steels because it was comparatively economical. CO2 gas shielded welding is an active gas shielded welding so it is also called MAG welding or MAGC welding. Gas-shielded metal arc welding or GTAW was another significant milestone in the history of welding. It was developed at Battelle Memorial Institute in 1948. This discharge tube is filled with gaseous mixture of CO 2 active medium helium and nitrogen with suitable partial pressures. The welding speed used for such welds is 17-25 cmmin. CO2 gas shielded welding belongs to active gas shielded welding so it is also called MAG welding or MAGC welding. The welding process works on constant voltage principle. Indeed lately is being hunted by users around us, maybe one of you. Individuals are now accustomed to using the internet in gadgets to view image and video data for inspiration, and according to the name of the post I will talk about about Co2 Welding Principle. The laser transition takes place between the vibrational states of CO 2 molecules. Resistance Welding Principle Working and Application. MIG stands for metal inert gas welding or sometimes it is known as Gas Metal Arc welding. A pressure is applied to the two pieces against the fixture. Gas-shielded metal arc welding or GTAW was another significant milestone in the history of welding. The active medium is a gas mixture of CO 2 N2 and He. Electric arc between the electrode and work piece closes the electric circuit. Welding isnt just a simple task but one that requires a high level of skill along with a working knowledge of basic physics chemistry and metallurgy principles. The heat may be supplied by electricity or by a gas flame. Soon electrode wires of smaller diameter made welding of thin materials more convenient.
The arc temperature may reach 10000F 5500C which is sufficient for fusion the work piece edges and joining them. Basic principles of welding. This discharge tube is filled with gaseous mixture of CO 2 active medium helium and nitrogen with suitable partial pressures.
Both gases mixed there and form a flammable mixture.
CO2 gas shielded welding belongs to active gas shielded welding so it is also called MAG welding or MAGC welding. The fire flame flow through nozzle and strikes at welding plates. The CO2 gas ejected from the nozzle decomposes into CO at high temperature and emits O2. The work piece is connected to the negative terminal and welding torch to the positive terminal.
