摘要
采用纵向可调拘束试验时最新研制的多元微量合金高强钢P460NL1的焊接热裂性能进行了试验研究，理论分析和试验结果都表明，该钢种产生热裂纹的倾向很小。
This paper describes a study on welding hot crack characteristic of recently-developed complex microalloy highstrength steel P460NL1 through longitudinal adjustable restrainttest. The theoretioal analysis and test result prove that this kind of steel has small tendency to form hot crack
