Regular MIG-MAG welding equipment may be used for assembling of elements made from iron alloys (both low-carbon and stainless steels) or copper alloys. This process requires a special welding wire made from copper with additives (aluminum or silicon) to be used. The melting point of this wire is lower, than that of steel and thus welded parts do mot melt. Basically this process is soldering, but the strength of joints and performance speed are quite close to welding.
Using this process, galvanized steel elements, for example can be joined together with no significant damage to zinc coating. This is very important for both welder`s health and corrosion protection of items.
An important condition for MIG-MAG soldering is the use of welding mixtures with a dosed carbon dioxide (CORGON 2) or oxygen addition. The type of the shielding mixture and wire composition depends on the materials, which are welded together. Welding machine operating mode used for MIG-MAG soldering differs from welding modes.
