| 20090041953 | Method for depositing a metallic substrate on a wall - In one aspect, a method for depositing a metallic substrate on a wall of a narrow depression of a metallic component is provided. A wire electrode is introduced into the depression and thereby bent in the direction of the wall by means of a guide. A suitable voltage is applied to the component and to the wire electrode in order to create an arc, which melts the wire electrode in certain regions. The molten material of the wire electrode is thereby deposited on the wall of the component. The wire electrode is progressively fed in during the depositing operation. | 02-12-2009 |
| 20100133239 | Submerged Arc Narrow Gap Welding With Oscillating Electrode - There is described a method for submerged-arc narrow-gap welding, in which the wire electrode is set in oscillating motion in the gap in order to produce a first bead, the arc moving backwards and forwards between one of the workpiece edges and a middle section of the gap so that the first bead does not extend from the first to the second workpiece edge. | 06-03-2010 |
| 20100193476 | Inert gas tube and contact tube of an apparatus for improved narrow-gap welding - An apparatus for improved narrow-gap welding is provided. The apparatus includes an inert gas tube within which a contact tube is arranged, the contact tube includes a wire feed for a melting wire. In one embodiment, the inert gas tube includes a plurality of cooling tubes in order to provide active cooling. In another embodiment, the inert gas tube is rectangular. | 08-05-2010 |
| 20100193477 | Inert Gas Tube and Contact Tube of an Apparatus for Improved Narrow-Gap Welding - An apparatus for improved narrow-gap welding is provided. The apparatus includes an inert gas tube within which a contact tube is arranged, the contact tube includes a wire feed for a melting wire. The end of the inert gas tube is ceramic. In another embodiment, the inert gas tube of the apparatus includes a plurality of materials with a high thermal conductivity. A first metallic material at the end of the inert gas tube has a higher thermal conductivity than a second material at a start of the inert gas tube. The first metallic material is molybdenum, tungsten, an alloy of molybdenum or tungsten, or copper or a copper alloy. | 08-05-2010 |
| 20100193571 | INERT GAS TUBE AND CONTACT TUBE OF AN APPARATUS FOR IMPROVED NARROW-GAP WELDING - An apparatus for improved narrow-gap welding is provided. The apparatus includes an inert gas tube within which a contact tube is arranged, the contact tube includes a wire feed for a melting wire. The contact tube is coolable in the interior. In another embodiment, the apparatus is formed from an inner core and an outer jacket wherein at the end of the contact tube, the contact tube has a ceramic coating. The coating is applied to the outer jacket and/or the inner core. | 08-05-2010 |
