| Abstract: | The component and mechanical properties of D36-Z35 steel was analyzed, according to special requirements of ships and marine facilities application environment. The welding process of double wires automatic SAW was conducted on D36-Z35 steel with the wall thickness of 38mm and the shielded metal arc welding process was used for repair welding. The welding procedure qualification tests were carried out for the said two welding process on the basis of standard request. Through NDT and serials mechanical tests, the results showed that application of reasonable design of the double wires automatic SAW and manual repair welding process, D36-Z35 steel can obtain excellent welded joint. On the premise of guarantee welding quality, it can improve the welding efficiency. |
