Comparison of Welded Joint Stress with Experimental and Finite Element Method Using of Hotspot Method
Abstract
The purpose of the welded structures is to combine the two different structures defined as the workpiece and the main material in order to ensure that they remain in the elastic deformation zone by meeting the loading conditions safely. Welding parameters such as preheating, welding speed, shielding gas selection, filler wire selection, voltage, current values affect the mechanical properties of the HAZ zone and the general structure, especially when welding fine-grained structural steels are performed. Strain gauge sensors can give normal stress and shear stress values for structures forced by static loadings depending on the stable x, y, z axes. The hotspot stress method used with the finite element method gives closer results to experimental studies. In this study, two different S960QL steels were combined with workpiece and main material using MAG welding. Data were taken from the strain gauge sensor connected to the samples prepared by the hotspot stress method. Using the finite element method, different types of models were analyzed and experimental data were compared with analysis outputs. As a result of the comparison, the most accurate welded joint analysis modeling with the hotspot method has been determined by the results of the experiment and analysis and has been proven with an accuracy rate of 89%.

Hotspot Yöntemi Kullanılarak Deneysel ve Sonlu Elemanlar Yöntemi ile Kaynaklı Bağlantı Gerilmelerinin Karşılaştırılması
Abstract
Kaynaklı yapıların amacı, iş parçası ve ana malzeme olarak tanımlanan iki farklı yapıyı birleştirmek ve yükleme koşullarını güvenli bir şekilde karşılayarak elastik deformasyon bölgesinde kalmalarını sağlamaktır. Özellikle ince taneli yapı çeliklerinin kaynağı yapılırken ön ısıtma, kaynak hızı, koruyucu gaz seçimi, dolgu teli seçimi, gerilim, akım değerleri gibi kaynak parametreleri HAZ bölgesinin mekanik özelliklerini ve genel yapıyı etkilemektedir. Gerinim ölçer sensörler, x, y, z eksenine bağlı olarak statik yükler tarafından zorlanan yapılar için normal gerilme ve kayma gerilme değerlerini verebilmektedir. Kaynaklı bağlantılarda hotspot gerilme yöntemi, sonlu elemanlar yöntemi ve deneysel çalışmalarda daha doğru sonuçlar vermektedir. Bu çalışmada iki farklı numunede S960QL çeliği, MAG kaynağı kullanılarak iş parçası ve ana malzeme birleştirilmiştir. Hotspot gerilme yöntemi ile hazırlanan numunelere bağlı gerinim ölçer sensörlerinden veriler alınmıştır. Sonlu elemanlar yöntemi kullanılarak farklı parametrelerde modeller analiz edilmiş ve deneysel veriler ile karşılaştırılmıştır. Karşılaştırma sonucunda hotspot gerilme yöntemi ile en doğru kaynaklı bağlantı analizi modellemesi deney ve analiz sonuçları ile belirlenmiş ve %89 doğruluk oranı ile kanıtlanmıştır.
