Patent ID: 8217295

Claim:
A method for producing a welded connection between first and second components each having a respective inside, outside and end face interconnecting the inside and the outside, the first component being formed of a ferritic basic body carrying an inside plating and having an end face provided with a buffer layer formed of a nickel-based welding material, and the second component being formed of an austenitic material, the method comprising the following steps: a) enclosing a weld groove between the end faces of the two components; b) connecting only the plating to the end face of the second component with a root formed of an austenitic material welded in the weld groove; c) welding an intermediate layer formed of a nickel alloy with at least 90% nickel onto the root, onto an end face of the plating, and onto the end face of the second component; and d) subsequently generating a weld seam with a nickel-based welding material in the weld groove still remaining.
