| titleOfInvention | Butt welding method |
| abstract | Using a hydrogen containing shielding gas and GTAW equipment, the method of welding a non-stainless steel workpiece on a first route pass may comprise a hose made of an elastomeric material having a water transmission coefficient of less than 275, preferably less than 100, or It is improved by using a shielding gas delivery system comprising a conduit and a tungsten electrode mixture comprising at least tungsten and lanthanum oxides, preferably tungsten, lanthanum oxide, yttrium oxide and zirconium oxide. Preventing moisture permeation through the elastomeric hose delivering the hydrogen containing shielding gas eliminates the extraction of molten weld metal during second pass filler welding after root pass welding. Electrode life is increased using tungsten mixtures. |
