Claim:
1. A method for connecting two components by welding, wherein at least one of the two components or a weld filler material used in the production of the weld joint consists of an air-hardening steel alloy, said method comprising: providing a joint extending from an inside toward an outside between the two components that are to be connected; welding a root layer in the region of the inside; welding of a fill layer adjoining the root layer; welding a first cover layer comprising adjacent bead tracks and adjoining the fill layer in a region of the outside; welding a second cover layer comprising a single bead track above the first cover layer; and wherein a welding current for welding the first cover layer and the second cover layer is adjusted in a non-linear manner with respect to a wall thickness of the two components so that a temperature in the region of the root layer on the inside is adjusted within an optimizing temperature range of approximately 600° C. to approximately 1000° C.
