Özet:

In this study, a large part of the ship used in the manufacture of three different thickness of Grade A ship plates were joined by submerged arc welding method. In order to determine the strength of welded joints to the tensile and charpy impact test were applied, as well as hardness and microstructure studies were conducted on samples. Tensile tests showed that rupture occurred in the base metal of all samples. From the results of charpy impact test, the highest charpy notch values were obtained from base metal and this is followed by HAZ and the weld metal. It was seen that all the welding parameters, weld metal hardness is higher than the HAZ and the base metal.
