Abstract

In this study, AH36 steel plates, commonly used in the hull of ships and the construction of tanks in the marine industry, were butt welded underwater using the shielded metal arc welding method and E6013 (GeKaTec UW E6013) rutile electrodes. Welding operations were carried out by expert industrial divers at a depth of 4 meters in a real sea environment. The plates were first subjected to non-destructive testing tests by the requirements of the AWS D3.6 standard. Then, hardness, Charpy impact, bending, and tensile tests were performed to determine the mechanical properties of the welded plates joined underwater. Finally, the results were interpreted together with the microstructural transformations in the weld area.

Abstract

Bu çalışmada, örtülü elektrot ark kaynağı yöntemi ile yerli E6013 rutil elektrotlar (GeKaTec UW E6013) kullanılarak gemi imalat sektöründe; gemilerin gövdesinde ve tankların yapımında yaygın olarak kullanılan AH36 çelik plakaları su altında alın alına birleştirilmiştir. Kaynak işlemleri gerçek deniz ortamında 4 metrelik bir derinlikte uzman sanayi dalgıçları tarafından gerçekleştirilmiştir. Plakalar ilk olarak AWS D3.6 standardının gerekliliklerine uygun olarak tahribatsız muayene testlerine tabi tutulmuştur. Daha sonra su altında birleştirilen kaynaklı plakaların mekanik özelliklerini belirlemek amacıyla sertlik, çentik darbe, eğme ve çekme testleri uygulanmış olup, sonuçlar kaynak bölgesinde meydana gelen mikro yapısal dönüşümlerle birlikte yorumlanmıştır.
