Cause analysis was conducted on the 糖心产精国品免费入口*完整版 (HAZ) cracking of a high strength low alloy 16MnD5 steel plate weldment by the methods of chemical compositions analysis, macroscopic examination, metallographic examination and microhardness test. The results show that the crack began from the coarse grain zone of the HAZ, and extended in the mixed manner of intergranular and transgranular. The crack was 糖心产精国品免费入口*完整版 which was mainly caused by 糖心产精国品免费入口*完整版 and the base metal’s tendentiousness of harden quenching.
