摘要
Abstract
The S355ML steel used in extremely cold areas has the characteristics of high strength and strict requirements for low-temperature toughness.By reasonably selecting welding materials and controlling the preheating temperature,maximum interlayer temperature and heat input,a submerged arc welding process of S355ML steel is developed for extremely cold areas with low temperature toughness of-50℃.The results of the welding process qualification test of submerged arc welding show that the strength of the joint meets the requirements,the plasticity is good,and the low-temperature toughness far exceeds the qualified value of the project.The process development is successful.关键词
