  • Clad member and method of manufacturing same
    Patent number: 5897719
    Abstract: A clad member is made up of a plate-like clad base material having on its surface a recessed portion, and solidified portions of a metallic material which is different in kind from the clad base material. The solidified portions are disposed in the recessed portion at a distance from each other and are bonded with the clad base material through melting. The clad member is manufactured by forming an elongated recessed portion on a surface of a plate-like clad base material. The recessed portion is filled with a comminuted metallic material which is different in kind from the clad base material. A laser beam is irradiated onto a plurality of regions which are separated from each other in a longitudinal direction of the recessed portion such that partly melted portions of the comminuted metallic material are generated to thereby bond the comminuted metallic material with the clad base material. The melted portions are solidified. The remaining non-molten portions of the comminuted metallic material are removed.
