Abstract
The paper treats welding of heat-resistant ferritic stainless steels alloyed with approximately 20% Cr and 5% Al. The major part of the paper is dedicated to welding of 20% Cr – 5% Al steel with 3 mm in thickness. Welding was carried out with five different welding processes, i. e., manual metal-arc, MIG, TIG, plasma arc, and laser beam welding processes, using a filler material and using no filler material, respectively. The welded joints obtained were subjected to mechanical tests and the analysis of microstructure in the weld metal and the transition zone. The investigations conducted showed that heat-resistant ferritic stainless 20% Cr – 5% Al steel can be welded with fusion welding processes using a Ni-based filler material.
Abstract
Es wird über das Schweißen von mit ungefähr 20% Cr und 5% Al legierten hitzebeständigen ferritischen nichtrostenden Stählen berichtet. Der größte Teil des Artikels behandelt das Schweißen eines 20% Cr – 5% Al-Stahls mit der Dicke von 3 mm. Es wurde nach fünf verschiedenen Verfahren geschweißt, d. h., Lichtbogenhand-, MIG-, WIG-Plasmalichtbogen- und Laserschweißverfahren, mit bzw. ohne Zusatzwerkstoff. Die gewonnenen Schweißverbindungen wurden mechanischen Versuchen und einer Analyse der Mikrogefüge im Schweißgut und in der Übergangszone unterworfen. Die vorgenommenen Untersuchungen haben gezeigt, dass die hitzebeständigen ferritischen nichtrostenden 20% Cr – 5% Al-Stähle mit einem Ni-Basis-Zusatzwerkstoff geschweißt werden können.
