One of them is about reducing dimensional shrinkage after welding process. Shipbuilders achieve this phenomenon by applying overall redundancy of the mismatch between the design and dimension of plates which is formed due to the welding shrinkage during joining of two parts. This situation adds significantly to the material cost when the entire ship is considered. Therefore, it is important to study the stability of welding parameters to achieve a high-quality welding. In this study, welding strength and distortion have been investigated for AH36 ship steel plate joined by submerged arc welding method. In this context, 18 experiments have been conducted using two different gap sizes, with ceramic back plate and double-sided welded without ceramic under the same welding groove, and also different welding methods, currents, welding speeds, and voltages. All welding grooves of samples were prepared as 45 degrees V type after computer numerical control (CNC) cutting. Specimens for mechanical tests were cut with abrasive waterjet cutting technique in order not to affect the weld metal and heat-affected zone. According to tensile test results, fractures in all specimens occurred outside the welding zone of the base metal. It was concluded that double-sided welding method increases the welding strength.eninfo:eu-repo/semantics/closedAccesssubmerged arc weldingship platedistortionAH36 steelArticle10.5957/JSPD.1600242-s2.0-850414349473414Q333533WOS:000422735100008Q3
