A welding mechanism for build up of a conical surface includes a base assembly with a base gear fixedly mounted thereto, and a slide rail assembly rotatable about a base axis. The slide rail assembly includes a slide rail positionable parallel to the conical surface, a slide carriage moveable along the slide rail, carrying a welding torch, a rotatable lead screw in threaded engagement with the slide carriage, and a carriage gear rotatable with the lead screw and engaged with the base gear. Rotation of the slide rail assembly moves the torch on the slide carriage circumferentially along the conical surface, and, simultaneously, rotation of the slide carriage assembly, by inter-engagement of the carriage and base gears, causes the slide carriage to move along the slide rail carrying the torch radially along the conical surface, the torch moving in a spiral path, about the base axis, along the surface.
