Research on Mechanical Property of Spliced Weld Metal for Large Diameter Head Made of 13MnNiMoR Steel
Taking 13MnNiMoR steel as the research object, two test coupons were welded respectively with H08Mn2MoA+SJ101 and H09MnNiMoG+SJ16G welding materials. Properties such as microstructure, tensile test, impact tests at -20℃ of two test coupons were analyzed after simulating head hot forming, recovery performance heat treatment, Max.PWHT and Min.PWHT. The results show that H09MnNiMoG wire with SJ16G flux have higher chemical composition of Mn, Ni, Mo in the weld metal, the structure of the weld zone is sostenite and a little amount of ferrite with fine grain, and the tensile properties are better at room temperature and high temperature.
