The invention relates to a method for welding two welding parts () by means of a fillet weld (), wherein a first welding part (), with a bearing surface at least in an edge area of an edge that is to be welded by means of a fillet weld, is brought into contact with a bearing surface of a welding part () and the welding energy () is supplied in an energy supply area during the welding process, exclusive of a surface () of the first welding part facing away from the bearing surface, said energy supply area being located at a predetermined distance from the edge of the first welding part. The welding energy is supplied in a direction, whereby the direction component thereof points perpendicular to the course of the fillet weld that is to be produced in the direction of an inner area of the first welding part, forming a welding angle of less than 90&#xb0; with the contact plane of the bearing surfaces of the first and second welding parts. The welding energy is supplied until at least the energy supply area of the first welding part and a sufficient area of the second part, which is adjacent to the energy supply area of the first welding part, and also the material supply area located between the energy supply area and the edge of the first welding part are melted and fused together. The invention also relates to a welding part for carrying out said method and to an electric component with a printed conductor, which is welded to a cooling body of at least one power semiconductor element.

An adjustable rear pistol sight has a sight base and a sight block. The sight block is secured in a recess in the sight base and has both windage and elevation adjustment capabilities. The sight base has a dovetail that will be receivable in a cooperatively shaped notch in a slide of a pistol with which the adjustable rear sight is intended for use. The sight has no sharp edges or surfaces and is essentially snag-free.
