A method of producing at least one conformal cooling passage in a part-producing mold, and a mold provided with such a conformal cooling passage(s). A conformal cooling passage is produced by creating an open channel in a molding surface of a mold of interest, the channel substantially conforming to the contour of the molding surface. A bridging weld formed from a plurality of connected weld beads is generated in the channel so as to span and seal the channel while enclosing an open passage in the bottom thereof. The remainder of the channel above its bridging weld is filled, such as by welding, and an exposed portion of the fill material in the channel may be subsequently shaped to conform with the contours of the molding surface surrounding the channel. A sub-surface conformal cooling passage is thus formed in the mold. |
