“…In addition, academic studies are carried out to determine and improve the mechanical properties of the welding area after joining the steels used in ship construction with various welding methods and welding parameters. The number of research on the joining of steels used in ship building with SAW or GMAW processes has been found to be quite little when the studies are analyzed (Donizete Borba, Duarte Flores, de Oliveira Turani, & Cardoso Junior, 2017; Gook, Midik, Biegler, Gumenyuk, & Rethmeier, 2022;Jokinen, Vihervä, Riikonen, & Kujanpää, 2000;Kim, Lee, & Choo, 2003;Sirisatien, Mahabunphachai, & Sojiphan, 2018;Wang et al, 2023;Yuan et al, 2022;Zhang, Coetsee, Dong, & Wang, 2020a, 2020bZhong et al, 2023;Zhong, Li, Basu, Wang, & Wang, 2022). On the other hand, as a result of the combination of 3701 coded lowmedium strength shipbuilding steel, which is used extensively in shipbuilding, with these two welding methods, it has been determined that no study has been carried out on the examination of the mechanical properties of the welding zone.…”

Merchant ships are generally built by joining steels with various welding methods. When the welding methods used in shipyards are examined, it is seen that gas metal arc welding (GMAW), submerged arc welding (SAW), covered electrode arc welding and tungsten inert gas (TIG) welding come to the fore. In the assembly of ship hull sheets, GMAW and SAW are generally preferred. In this sense, it is extremely important to characterize the mechanical properties of the weld zone after welding of the shipbuilding steel joined by these two welding methods. When the studies examined, although there are few studies on the joining with GMAW and SAW of shipbuilding steels, no study has been found on the comparative examination of these two welding methods. In this context, within the scope of the study, 3701 shipbuilding steel, which is used extensively in shipbuilding, was joined with SAW and GMAW methods and the hardness, tensile, impact and bending properties of the welding zone were examined comparatively. In consequence of the tests, it was determined that higher mechanical properties were obtained than the base metal in both welding methods. Also, it was found that the welding zone of the shipbuilding steel joint by the SAW method had relatively better mechanical qualities.
