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.

由试验结果表明，14MnNbq钢焊接HAZ最脆区出现在一次热循环的埋弧焊过热区及二次热循环的埋弧焊过热区+不完全重结晶区；14MnNbq钢比SM490C钢有更强的过热脆化倾向，为确保焊接热影响区韧性，焊接时应适当控制焊接线能量。
