摘要: A method is used for laser welding a workpiece along a welding line. At least two laser beams, which are offset in relation to one another, are guided along the welding line by moving an optical deflector unit. The method may be used for welding closure pins and casting induced openings of gas turbine blades.

摘要: A method of forming a hydrogen rich gas from a source of hydrocarbon fuel. A vapor of the hydrocarbon fuel and steam is brought in contact with a two-part catalyst having a dehydrogenation powder portion and an oxide-ion conducting powder portion at a temperature not less than about 770°C. for a time sufficient to generate the hydrogen rich. The H2 content of the hydrogen gas is greater than about 70 percent by volume. The dehydrogenation portion of the catalyst includes a group VIII metal, and the oxide-ion conducting portion is selected from a ceramic oxide from the group crystallizing in the fluorite or perovskite structure and mixtures thereof. The oxide-ion conducting portion of the catalyst is a ceramic powder of one or more of ZrO2, CeO2, Bi2O3, (BiVO)4, and LaGaO3.
