Process

Metal inert gas welding

MIG welding is a metal shielding gas welding process (GMAW) with inert gas, in which the light arc burns between a continuously fed melting wire electrode and the material. The melting electrode supplies the additive material for forming the weld. MIG welding can be used simply and economically with nearly all materials that are suitable for welding. Different shielding gases are used, depending on the requirement and the material.

Metal active gas welding

MAG welding is a metal shielding gas welding process (GMAW) with active gas, in which the arc burns between a continuously fed melting wire electrode and the material. The melting wire electrode supplies the additive filler metal for forming the weld. MAG welding can be used simply and economically with nearly all materials that are suitable for welding. Different shielding gases are used, depending on the requirement and the material.

Tungsten inert gas welding

TIG welding is tungsten shielding gas welding process (GTAW) with inert gas, in which the arc burns between a non-melting tungsten electrode and the material. TIG welding can be used simply and economically on a variety of materials. Different shielding gases are used, depending on the requirement and the material.

Laser beam welding

Laser beam welding - in brief: laser welding - is a beam welding process that is used to join metals. The heat required to connect the parts is generated by the laser beam which is focussed onto the weld. Laser welding is a very fast and efficient welding process that is highly suited for automated processes.

Tungsten plasma welding / Plasma metal inert gas welding

Plasma welding is a shielding gas welding process with inert gas and a further development of the TIG welding procedure. Here, the arc burns between a non-melting electrode and the material. The plasma beam, which is used as a heat source, is created by a high supply of energy that makes the shielding gas electrically conductive. The arc is constricted and thereby reaches a higher energy density than during TIG welding. Plasma welding is suitable for all electrically conductive materials.

Plasma arc cutting

Plasma cutting is a arc cutting process in which the arc burns between a non-melting electrode and the material. The heat source is a beam of very hot electrically conductive gas, the so-called plasma beam. Plasma cutting is suitable for all electrically conductive materials. Various cutting gases are used in plasma cutting depending on the requirement and material.

Arc electrode welding

Manual metal arc welding is a metal arc welding process (MMAW) in which an electrical arc burns between a sheathed rod electrode and the material. No shielding gas is used in manual metal arc welding. The sheathed melting electrode forms a shielding gas to protect the smelt and supplies additives to create the required seam. Manual metal arc welding can be used on nearly all materials suitable for welding, simply and efficiently. Shielding gas is not supplied but is created – depending on the requirement and material – when the electrode sheath melts. The procedure is also used in small and medium-sized businesses and when building ships, pipelines as well as steel constructions and bridges outdoors.
