Abstract
In this study, the effect of welding speed on the laser welding of AISI 430 ferritic stainless steel with AISI 1010 low-carbon steels was investigated. Laser welding experiments, were carried out under argon atmosphere, 2000 W constant welding power and 100, 200, 300 cm/min welding speeds. The microstructures of the welded joints were examined by optical microscopy and SEM analysis. The tensile strength of the welded joints was measured. The result of all observations, tests and measurements indicated that the best properties were observed at the specimens welded at 100 cm/min welding speed.
Kurzfassung
Bei dieser Untersuchung wurde der Einfluss der Schweißgeschwindigkeit auf das Laserschweißen von ferritischem rostfreiem Stahl AISI 430 mit kohlenstoffarmen Stählen AISI 1010 untersucht. Die Laserschweißexperimente wurden unter einer Argon-Atmosphäre, einer Dauerschweißleistung von 2000 W und Schweißgeschwindigkeiten von 100, 200 und 300 cm/min ausgeführt. Mit der Lichtmikroskopie und der REM-Analyse wurden die Mikrostrukturen der Schweißstöße untersucht. Es wurde die Zugfestigkeit der Schweißstöße gemessen. In dem Ergebnis aller Feststellungen, Tests und Messungen zeigte sich, dass die besten Eigenschaften bei den Proben festzustellen waren, die mit einer Schweißgeschwindigkeit von 100cm/min geschweißt worden waren.
