Steel 35# based method for melting and depositing composite cladding layer through synchronous powder feeding by two cylinders

The invention provides a steel 35# based method for melting and depositing a composite cladding layer through synchronous powder feeding by two cylinders. the method comprises the following steps: selecting alloy powder, wherein the alloy powder comprises Ni50 or Ni60 metal powder and 316 austenitic stainless steel metal spherical powder; preheating a to-be-clad workpiece at the preheating temperature of 500-690 DEG C; setting the laser cladding technological parameter, and carrying out laser cladding on the surface of the to-be-clad workpiece to form a composite cladding layer; and after laser cladding is finished, carrying out thermal treatment at the temperature of 200-500 DEG C to eliminate thermal stress generated through laser cladding. The steel 35# based technological method for melting and depositing through synchronous powder feeding by two cylinders realizes surface modification and can effectively improve the overall strength and corrosion resistance of a structure. 本发明提供基于35#钢的双筒同步送粉熔化沉积复合熔覆层的方法，
