Abstract: In a first aspect, the invention relates to a method for achievement of a welded joint between two parts, e.g. a coupling part (1) and a drill shank (2), included in a cutting tool. Characteristic of the invention is that a shim (14) is applied in a peripherically opening gap between the parts, which shim has a predetermined shape corresponding to the shape of the gap, and then the material is melted and welded together in the boundary zone between the contact surfaces of the shim and the analogous contact surfaces of the two parts by means of a laser beam (22) directed to the periphery of the shim. In a second aspect, the invention also relates to a cutting tool as such.
