Abstract: A device for fabricating a tank head prior to attachment to a tank. A movable turntable of the invention holds the tank head horizontally on its rotatable top surface. The movable turntable travels on rails so that is can move the tank head under an overhead frame of the invention. The overhead frame is provided with frame rails on which a movable burner and a movable attachment holder independently travel so that they can be accurately positioned over the head. The movable burner can be lowered and raised in order to cut holes in the head at desired locations on the head. The movable attachment holder and an attachment that is removably secured to the attachment holder can also be lowered and raised in order to properly position the attachment relative to a hole in the head so that the attachment can be tack welded to the head.
