ABSTRACT:
An automatic welding apparatus and an automatic milling apparatus for machining welding grooves in order to weld a three-dimensional surface such as a ball tank or the like are disclosed. A welding wire spool is accommodated within a case and a cover to prevent the welding wire from being oxidized and from being contaminated with foreign materials. The automatic milling apparatus is installed to form welding grooves on the both sides of the objects to be welded, in the case where a welding is performed on a three-dimensional curved surface. A guide roller having a handle is installed to control the machining depth of the grooves, and an idling type nylon guide roller is installed in closed contact with the shaft of a cutter, thereby adjusting the distance between the rail and the groove, and adjusting the deviations of the depth of the grooves, which are caused by the machining inaccuracies due to the deviations of the three-dimensional curvature.
