A process and apparatus are disclosed for repairing damaged synthetic textil es using ultrasonic welding techniques by replacing the damaged area with a like synthetic patch. High frequency vibrations are applied to the patch producing a sealed perimeter, thema flat anvil with a planar surface area adequate to accommodate the apparatus mounted on an electromagnetic press base is placed under the damaged layer and the apparatus is placed thereon. High frequency vibrations are applied to the damaged area forming a sealed perimeter by applying electromagnetic energy to counteract the opposing forces created when the horn makes contact with the anvil. The damaged area is removed leaving a sealed aperture, and the patch is position ed over the aperture forming a lap joint. High frequency vibrations are applied to they lap joint producing a patch having a planar surface bonded flush with the top and bottom-side surfaces of the damaged textile.
