ABSTRACT:
A method and apparatus for building a workpiece of a desired geometry by deposit welding with a reusable preform. The reusable preform forms, supports, and cools the deposited molten weld material puddle while the weld material is solidifying thereby eliminating the need for a conventional preform. The reusable preform may be mobile or stationary in any shape, e.g., a block, a cylinder, or a belt. It is manufactured from either a combination of or exclusively of, a ceramic material or a material with high thermal conductivity.
