摘要

The invention relates to a method for welding cold-rolled narrow strips (5) in the form of flat wire or profiles of a TWIP steel, in particular for use in flexible pipes (1), in particular in flexible pipes (1) for offshore applications, in which Ends (7) of the welded portions of the narrow band (5) relative to the main loading direction (8) of the narrow band (5) bevelled and arranged to fit each other and the weld (9) by a fusion welding with a relatively small melting zone and / or a relative low welding temperature is performed. Also, a cold-rolled narrow strip (5) in the form of flat wire or profiles of a TWIP steel, in particular for use in flexible pipes (1), in particular in flexible pipes (1) for offshore applications, proposed in which to be welded Have narrow bands (5) each matching, to the main load direction (8) of the narrow band (5) bevelled ends (7).
