WELD ASSEMBLY PRODUCTION

We use two types of welded joints to weld assemblies – resistance welding and electric arc welding.

Resistance welding is the process of creating an inseparable welded joint by heating the metal with an electric current through it and plastically deforming the joint zone under the action of a compressive force. Resistance welding is predominantly used in industrial mass production or series production of the same type of products. We use stationary resistance welding machines.

Electric arc welding is a type of welding in which metal is heated and melted by an electric arc. The arc temperature (up to 7000°C) exceeds the melting point of all existing metals. An electrode is a metal wire of a specific grade to which a current is given by a current supply mouthpiece. The wire is melted by an electric arc, and the wire is fed automatically to maintain a constant arc length. A special gas, supplied from the welding torch together with the electrode wire, is used for atmospheric protection. We have three stationary arc welding stations where we produce various welded assemblies.
