Abstract (2. Language): 
In this study, a numerical method has been developed for modelling underwater welding. The geometry used in the study is a three-dimensional thick rectangular plate. Transient heat conduction in the plate has been calculated numerically including a point heat source simulating the arc and convective, radiative and boiling surface boundary conditions. Finite volume method has been used as the numerical scheme. A variable mesh size centered around the moving heat source has been used in the calculations. The validity of the results was checked by comparison with some solutions in the literature.
Abstract (Original Language): 
Bu çalışmada, su altı kaynağının modellenmesi için sayısal bir yöntem geliştirilmiştir. Çalışmada kullanılan geometri üç boyutlu kalın bir plakadır. Plaka içerisinde zamana bağlı ısı iletimi kaynak elektrodunu simüle eden noktasal bir ısı kaynağı ve taşınım, ışınım ve kaynama sınır koşullarını kullanarak sayısal olarak hesaplanmıştır. Sayısal yöntem olarak sonlu hacim yöntemi kullanılmıştır. Hesaplarda hareketli ısı kaynağının etrafında değişken aralıkta bir grid yapısı kullanılmış ve sonuçların geçerliliği literatürdeki bazı çözümlerle karşılaştırılarak kontrol edilmiştir.
