Abstract: A dissimilar metal connection arrangement comprising a dissimilar metal connection between a first member made of a first metal and having a first end, and a second member made of a second metal different from said first metal with regard to its metallurgical behavior, and having a second end, wherein the first end of the first member is fixedly connected to the second end of the second member. An increased lifetime of the connection is achieved by arranging a heating means at said dissimilar metal connection for controlled heating of said dissimilar metal connection.

Abstract: A process for welding pipe connections for high temperature applications, particularly in power plants, including a first pipe section and a second pipe section. The first pipe section is made of a ferritic material having a first coefficient of thermal expansion. The second pipe section is made of an austenitic material having a second coefficient of thermal expansion, which is different from the first coefficient of thermal expansion. The weld joint is made of an austenitic filler material which has a third coefficient of thermal expansion which is in the range of the second coefficient of thermal expansion. The process includes axially aligning the first and second pipe sections to be connected, making an at least partially V-shaped weld joint open radially inwards, and performing an inside welding process inside the first and second pipe sections to be connected. The invention is further directed to such a pipe connection.
