ABSTRACT:
A method for welding and heat treating straight bead welded pipes made of austenitic, ferritic or austenitic-ferritic rust-resistant steel includes welding a straight bead on a pipe forming a welding seam region, a heat affected zone and a remaining region, and annealing the pipe after welding the straight bead by only partially solution-annealing in the welding seam region and the heat affected zone, while heat treating the remaining region at a reduced temperature. An apparatus is also provided for carrying out the method.
