Abstract:
A method for selectively adhering braze powders to a surface comprises applying a binder material to a surface, depositing a braze powder on the binder material, and then directing a laser beam onto the braze powder while the laser beam moves along a predetermined path relative to the surface. The laser beam selectively heats the braze powder and the binder material along the predetermined path such that the binder material is removed and the braze powder is sintered and bonded to the surface. Thus, a braze deposit is formed at one or more predetermined locations on the surface. After forming the braze deposit, excess braze powder and binder material, that is, the braze powder and binder material not selectively heated by the laser, are removed from the surface.
