摘要

The invention relates to an automatic welding arrangement and an automatic milling arrangement for machining weld gaps for welding a three-dimensional surface, such as a spherical vessel or the like. A reel of welding wire is arranged in a box with cover in order to prevent the welding wire being oxidized or contaminated by foreign material. The automatic milling arrangement 22 is installed in order to form weld gaps H on both sides of the workpieces A, A' that are to be welded in a situation where the welding is performed on a three-dimensional, curved surface. A guide roller having a handle is arranged in order to control the machining depth in the gap H and a free-running nylon guide roller is arranged in close contact with the shaft of the milling cutter, the distance between the rail 4, R and the gap H, and variations in the depth of the gap due to machining inaccuracies being adjusted on the basis of deviations in the three-dimensional curvature.
