日本材料研究机构超级钢铁研究中心与JFE钢铁公司共同开发了可应用于高强度钢焊接的材料。该焊接材料是在以铁为基体的材料中,通过添加铬与镍,在低温下改变焊接金属的组织,进而提高焊接区的疲劳强度,同时,防止焊接时由于氢引起的裂纹,不仅无需后续热处理,而且也免去了焊前的预 Japanese materials research institute Super Steel Research Center and JFE Steel jointly developed the material can be applied to high-strength steel welding. In the iron-based material, the welding material changes the structure of the weld metal at a low temperature by adding chromium and nickel to further improve the fatigue strength of the weld zone and prevent the crack caused by hydrogen during welding, Heat treatment, but also eliminates the pre-welding
