The test results show that the crispest HAZ occurs in the process of welding of the 14MnNbq steel on the first heat circulation submerged welding overheat zone and the second heat circulation submerged welding overheat zone plus the not entirely re crystallized zone. The 14MnNbq steel has a tendency of being crisper due to overheat than the SM490C steel is. In order to ensure the toughness of the welding HAZ′s, the welding wire capacity should be properly controlled during welding.
