Özet

Reproducible good weld quality and economical benefit of underwater-welding require a complete automation. For this purpose Gas Tungsten Arc-welding (GTA or TIG) offers numerous advantages, especially for the root and the following hot pass run. Disadvantages of GTA-welding are the low weld deposit rate and the limited lifetime of the tungsten electrode. Already small wear damages cause wide alterations of the arc under high surrounding pressure, so that a suited choice of the electrode enables to increase the productivity considerably. Therefore the influence of the electrode features on welding process, arc stability, arc ignition, weld geometry and electrode wear has been investigated. For quick and elementary selection of electrode an assessment catalogue was elaborated.
