Abstract
Plasma Transferred Arc Welding (PTAW) process parameters were optimized for joining 316 stainless-steel plates to produce weld joints with maximum tensile strength, impact strength and hardness. Taguchi technique was applied for optimizing the selected welding parameters such as welding current (I), welding voltage (V) and powder feed rate (PFR). L9 orthogonal array was selected according to the aforementioned factors with three levels and experimental tests were performed. Signal-to-noise (SN) ratio was used to evaluate the experimental results. The results indicate that the welding voltage has the greatest infiuence on tensile & impact strength and welding current is the significant factor for hardness.
Kurzfassung
Für die Verbindung von 316-Edelstahl-Platten wurden die Prozessparameter des Plasma-Pulver-Auftragsschweißens optimiert, um geschweißte Werkstücke mit maximaler Zugfestigkeit, Schlagzähigkeit und Härte herzustellen. Dabei wurde die Taguchi-Technik angewendet, um die ausgewählten Schweißparameter wie Schweißstromstärke (I), Schweißspannung (V) und die Pulverzufuhr (PFR) zu optimieren. Es wurde ein L9 orthogonales Feld gewählt, bezogen auf die vorgenannten Faktoren mit drei Ebenen und experimentelle Untersuchungen wurden durchgeführt. Mittels der Signal-Rausch-Verhältnisse wurden die experimentellen Ergebnisse evaluiert. Die Ergebnisse zeigen, dass die Schweißspannung den größten Einfluss auf Zugfestigkeit und Schlagzähigkeit hat, während die Schweißstromstärke für die Härte von Bedeutung ist.
