MAG welding – The mixture has to be right
When welding with active gases mixtures are used, which have a protective function. Because the oxygen must be kept away from the so-called sweatband, so it comes to an oxidation-free connection of the metal parts. Only then can the seams really hold.
The protective gases used are argon, carbon dioxide or a gas mixture. A higher economic efficiency can be achieved by the optimal gas selection. Helium additives also expand the performance range.
TIG welding – For clean seams
In contrast to MAG welding, no welding spatter occurs during this process. An inert gas that does not react chemically with the materials prevents an effect between the melt and ambient air. Often argon or helium are used for these purposes. In addition, the low and concentrated heat input leads to negligible welding distortion. TIG welding is primarily used where seam quality is important and not speed.
Cutting – Purity is needed
In this thermal cutting process several prerequisites must be ensured. On the one hand, the material must be low or unalloyed steel. In addition, the ignition temperature must be below the actual melting temperature of the material. And to keep the process economical and efficient, the oxygen should be 99.995% pure. Otherwise, cut surface quality, cutting speed and oxygen consumption are in poor ratio.
