Abstract
PURPOSE:To perform powder build-up welding with satisfactory strength without strain by sticking powder added with adhesive to a metal worn part by using a receiving die and drying and fixing said powder and afterward, depositing it on the worn part by a laser beam heat source. CONSTITUTION:The powder 2 which is formed by adding an adhesive to stellite powder is stuck along a lower surface recessed part of the receiving die 1 which is superposed on a moving blade 05 and the powder 2 added with adhesive is stuck to the build-up place. At the same time, the powder 2 added with adhesive is heated by a heater, etc., of the receiving die 1 and dried and fixed on the moving blade 05 and afterward, the laser beam heat source 3 is moved in parallel with the upper part of the front edge part of the moving blade 05 to perform the welding work and a build-up welded zone 4 is being formed. By this method, defects on the strength such as a pinhole do not occur on the joined part and the high strain is not caused and the firm powder build-up welding with few joining man-hours is performed.
