Interestingly, Disney has included Nice Classification class 06 in their trademark, which basically seems to cover all sorts of metalworks and products made from metal in general. Class 40 (which in addition to welding covers all sorts of random other services, including printing both classic and 3D, glass making, cheese refining, waste separation, …) on the other hand isn't included, so a Mickey Mouse-branded welding business should in theory be fine as long as you don't try to sell Mickey Mouse-branded steel girders or pipes as well :-)
