A plurality of welding torches are used to weld in the groove, such that at least some of the welding torches perform a first welding pass, the welding characteristics of the torches are adjusted and at least some of the welding torches are used to perform a second welding pass. At least one torch welds in a first sector in the first welding pass and a second sector in the second welding pass, the second sector being different to the first. The sectors might overlap or might not overlap.

摘要： A method of operating a plasma arc torch system includes placing a work piece to be cut on a table of the plasma arc torch system, wherein at least a portion of the work piece has a planer surface facing away from the table. A plasma arc torch is positioned adjacent the planer surface of the work piece using a positioning apparatus, wherein the positioning apparatus has at least five degrees of freedom about which it can move the plasma arc torch relative the work piece for cutting the work piece on the table. The method further includes angling the torch relative the planer surface of the work piece such that the torch is held at an angle of between about 1 and about 4 degrees from perpendicular with the planer surface to back burn a produced kerf such that a kerf edge is perpendicular relative the planer surface of the work piece. Additionally, the planer surface of the work piece is calculated by contacting the work piece with the torch at least three times.

摘要： A mechanism for adjusting an orientation of an electrode in a plasma processing chamber is disclosed. The plasma processing chamber may be utilized to process at least a substrate, which may be inserted into the plasma processing chamber in an insertion direction. The mechanism may include a support plate disposed outside a chamber wall of the plasma processing chamber and pivoted relative to the chamber wall. The support plate may have a first thread. The mechanism may also include an adjustment screw having a second thread that engages the first thread. Turning the adjustment screw may cause translation of a portion of the support plate relative to the adjustment screw. The translation of the portion of the support plate may cause rotation of the support plate relative to the chamber wall, thereby rotating the electrode with respect to an axis that is orthogonal to the insertion direction.

摘要： Provided are metal structures and methods of forming such structures for use in oil, gas and/or petrochemical applications that are joined with non-ferrous weld metal compositions or a high alloy weld metal compositions. The welded metal structures include two or more segments of ferrous or non-ferrous components, and fusion welds, friction stir welds or a combination thereof bonding adjacent segments of the components together, wherein the welds comprise a non-ferrous weld metal composition or a high alloy weld metal composition that is substantially different from the metal composition of the two or more components. The resultant welded structures exhibit improvements in fatigue resistance, toughness, strain capacity, strength, stress corrosion cracking resistance, and hydrogen embrittlement resistance compared to traditional iron-based weld compositions. The structures and methods of forming such structures are advantageous in joining metal components in applications for natural gas transportation and storage, oil and gas well completion and production, and oil and gas refinery and chemical plants.
