چکیده مقاله
In this study, ASTM A516 Grade 70 sheet with a thickness of 16 mm was used to build a tank under emergency nitrogen pressure for LADLE TURRET movement In order to create a connection between the base metals, assembly was performed and in order to perform melting welding operations, it was necessary to first prepare the sheets on one side according to the appropriate connection design For this purpose, they were prepared for butt joint with V shaped groove The accuracy of flattening and the absence of cracks in the samples prepared by the penetrant test were investigated Instructions were prepared and adjusted for welding inspection based on the parameters required for welding, and in this study, the inlet temperature was considered to be about 0 9 1 kJmm 1 Welding parameters were selected in such a way that the best fluidity and permeability were obtained while preventing additional heat from entering the molten pool To inspect the lens and the wall of the tank, two non destructive tests, one penetrating liquid, to check the penetration of welding and root welding, and also to check for important defects such as lack of penetration and incomplete melting, used ultrasonic test with 70 degree angle probe The results showed that by observing the parameters mentioned in the inspection instructions and also the presence of skilled welders, flawless and high quality welding will be achieved
