Metal welding uses significant temperature elevation when the oxidation processes are intensified. It results in the generation of the oxide film on the metal surface: the longer the oxidation reaction the more complicated the material welding is. Application of carbon dioxide or argon enables the isolation of the welding area from oxygen exposure. Gases actually displace it from the working area preventing the oxidation process.
Argon-arc and СО2 welding are used when a reliable and thorough connection of thin elements is required (for example, in the automobile industry) as well as for operation with difficult-to-weld metals, in particular aluminum.
Carbon dioxide welding is performed using a gas cylinder and wire as filler material that includes chrome, silicon, and other metals in its composition (the filler material is to be chosen based on materials of the components to be welded).
The process is as follows:
The demand for CO2 welding is ensured by its efficiency, reliability, and quality. The formed seams are smooth; the strength of the joint is not in doubt. The welding process is quite fast and ensures high performance of the technique. And finally, the low price of carbon dioxide makes CO2 welding method one of the cheapest.
Argon arc welding is performed using argon, an inert gas that does not react with other elements including oxygen. Just as in the case of CO2 welding the technique involves the use of filler wire. Argon does not affect the melted metal and does not change its properties. In addition, argon is heavier than other gases in air composition so it easily displaces all kinds of impurities from the welding zone.
Argon welding is performed in several stages:
The advantages of argon arc welding include high efficiency, the ability to form thin, thorough seams, as well as the protection of components from deformation due to the low heating temperature.
