PROBLEM TO BE SOLVED: To provide a metal processing method capable of easily removing an oxide film and an oxide scale generated due to melting, capable of preventing deformation of metal due to rapid cooling of a melting portion, and capable of reducing generation of waste for achieving cost reduction.SOLUTION: In a metal processing method for performing a secondary processing process which is any one of welding, coating, or metal plating to metal after subjected to a melting process after performing the melting process in which an oxide scale and an oxide film are generated on a metal surface, between the melting process and the secondary processing process, dry ice blast is performed, and a surface processing process capable of cooling heat of the metal heated by the melting is used.SELECTED DRAWING: Figure 1 |
