| Abstract: | The 60 mm thick heavy plate of 16MnR was welded by using straight polarity direct current automatic submerged-arc welding method with suitable welding parameters(electric current is 450 A;welding speed is 140 mm/min).The microstructures of the welded joint were observed and analyzed,and the surface microhardness of the welded joint was measured.The results showed that good appearance and uniform structure were obtained at the welded joint region,and the maximum micro-hardness was found in the welded heat af... |
