Abstract
A method and apparatus for building an axially symmetrical workpiece of desired geometry by deposit welding which uses a translatable welding head for depositing molten weld material and a rotatable, reusable shoe which translates with the welding head. The rotatable, reusable shoe forms, supports and cools the deposited molten weld material puddle while the weld material is solidifying thereby eliminating the need for a conventional preform.
