Orbital Welding

The main field of application of the WIG – Orbital welding method are: Tube – in – tube – connections Tube –  formpiece – connections Tube – in – ground – connections The WIG-orbital welding is based on the Wolfram Inert Gas Process (WIG), which allows to bring  energy and weld material into the welding point optimally.  The pulse technique used at this, makes it possible to control the fusion and setting of the weld puddle, which results in an optimal success of the process in every welding position. Welding connections are non-detachably and the most save connection of pipelines and weld material. The cartridge of WIG-orbital welding is a reaction to the growing demand from the market, which always expects high-quality welding-connections from metal-tubes at economic conditions. Not least special high-quality steels in several qualities and surface-classes are widely-used in the industry. These have to be connected not only successful but also quality-deserved. Advantages of this method: High method success High reproduction-ability Short production-period Low oxide-creation Highest quality of the welding seam Absolutely reproducible welding results Operational also with a manual non-reachable welding point small contamination of the medium with foreign particles economic production due to automatic welding large application zone due to good adaptability able to keep records (ISO 9000) usable for constructions and building yards A Standard-Orbital welding apparatus is made of three components: Welding power-source Orbital welding tools for closed or open construction type Cold wire unit   General requirements To assure a reproducible WIG-orbital welding the following requirements have to be classified  as important: Trained employees (knowledge in standard-WIG-welding technique) Quality and tolerances of the prefabricated parts which have to be welded Environmental effects Types and qualities of the welding- and forming gases Prefabrication of the tungsten electrode Optimal weld seam preparation and positioning accuracy Cleanliness Knowledge about the chemical analyses of the welding parts and also the expected irregularities Calculated and tested welding programs
