Abstract Scope |
Laser welding widely used in the joining of materials due to the advantages provides. In this study, the aim is to investigate the suitability of different ferritic stainless steels for laser welding method. Within the scope, welding of 0.5 mm thickness of ferritic stainless steel sheets of different grades (430, 430Ti and 441) was performed by solid state disk laser and welding parameters were determined as 1300 Watt power, 6 m/min speed welding in continuous wave mode. As a shielding gas, argon was used. Metallographic examinations, SEM-EDS analysis, microhardness measurement, tensile, cupping and bending tests were carried out with welded and unwelded samples. Thus, the structure and property relationships of ferritic stainless steels joined by laser welding were examined and compared. As a result, adequate welding quality could not be achieved in 430 samples and it was observed that the welding ability was insufficient compared to 430Ti and 441 samples. |
