A METHOD FOR MANUFACTURING OF COATED STEEL WELDS WITH GOOD CORROSION RESISTANCE AND FATIGUE PROPERTIES

摘要

Provided is a method for manufacturing a plated steel sheet welding member having excellent corrosion resistance and fatigue characteristics. The manufacturing method of the plated steel sheet welding member of the present invention comprises the steps of providing a galvanized steel sheet having an overlap joint weld; And a step of supersonically spraying a mixed powder of zinc or Ni powder having a diameter of 5 to 50 µm and hard particle powder having a diameter of 10 to 100 µm on the surface of the overlapping joint welding portion.
