Abstract
An apparatus for building an axially symmetrical workpiece of desired geometry by deposit welding which uses a welding head 18 for depositing molten weld material 14 and a rotatable, reusable preform 10 which translates with the welding head 18. The reusable preform 10 is provided with means for varying its shape 22 to minimize the weight of the preform 10. The rotatable, reusable preform 10 forms, supports and cools the deposited molten weld material puddle 14 while the weld material is solidifying thereby eliminating the need for a conventional consumable preform.
