摘要： The multi-layered heat resistant metal tube is disclosed. This tube has excellent anti-coking characteristics and is suitable for use under the conditions where carbon tends to deposit and accumulate thereon due to contacting with hydrocarbons at a high temperature. The tube is made by forming weld-mounted overlaid layer of CrnullNi alloy by building-up welding over the inner surface and/or the outer surface of a substrate tube made of a heat resistant metal. The CrnullNi alloy comprises 35% by weight or more of Cr and satisfies the relationship: Ni(w%)null0.5Cr(wt %). Building-up welding is preferably carried out by PPW (Plasma Powder Welding) in which the filler metal is supplied in the form of powder.

摘要： Devices and methods are provided that control gas flow to a plasma arc torch local to a torch handle. Generally, a plasma arc torch is provided that comprises a gas control device operable with a torch lead and a torch head, and an activation member operable with the gas control device. Accordingly, the activation member activates the gas control device such that gas flow is supplied from the torch lead to the torch head, and the activation member deactivates the gas control device such that the gas flow is terminated. Further, the activation member may comprise a trigger system, a button, or a safety member, among others. Moreover, the gas control device may comprise a gas control valve or a switch that activates a gas control device disposed within a power supply, among others.

摘要： Hybrid welding process and unit for welding metal workpieces, such as tailored blanks, by using a laser beam and an electric arc, preferably a plasma arc, in which process, after a welded joint has been produced, the laser beam is sent and/or deflected into radiation absorption means, such as an absorption cavity, allowing the radiation of the said beam to be absorbed. The beam continues to be deflected during the welding stop phase after producing one welded joint and before starting to weld a second welded joint. The process and the unit of the invention are particularly suitable for the mass production of workpieces for the motor-vehicle industry, such as tailored blanks that can be used to manufacture, for example, motor-vehicle body components, or for the mass production of pipes.

摘要： A welding apparatus spot welds two or more overlapping sheets having a coating, such as zinc coated steel or aluminum alloy with an oxide coating. A hole is formed in the upper sheet at the desired point of spot welding. A clamping cup of a plasma arc passes surrounds the hole and contacts the upper surface of the upper sheet. The torch heats the sheet, allowing entrapped vapors in the coating on the lower sheet to vent freely. Filler wire is added to fill the hole and to secure the overlapping sheets together. If the overlapping sheets are zinc coated steel, preferably the filler wire is copper based.
