ABSTRACT:
This invention provides a process involving submerged arc welding for nickel containing steel such as steel containing 3.5 weight percent of nickel. The process uses a bond type flux of specific composition to suppress the oxygen content in the weld metal. Further, the process utilizes a cored welding wire including a core material of specific composition. As the result, it is possible to obtain a weld metal of high impact-resistance at low temperatures such as minus 100.degree. C.
