    摘要： Medical apparatus includes a first hypotube formed from Nitinol and a second hypotube formed from a nickel alloy such as MP35N. A laser weld is formed between the first hypotube and the second hypotube. A third hypotube of stainless steel may be welded to the other end of the second hypotube., The apparatus includes an outer diameter that is substantially consistent along a length of the apparatus and an inner diameter that is substantially consistent along a length of the apparatus. A method of joining the hypotubes is disclosed.

    摘要： The invention relates to a method for joining workpieces (12, 13) using a laser beam (7), wherein the laser beam (7) is focused onto a focal plane downstream of the machining plane in the beam propagation direction and subdivided into a plurality of partial beams (19) by means of a beam dividing device (6). The subdivision is effected in a geometric manner, i.e. the partial beam cross sections emerge from a division of the geometric form of the beam cross section of the laser beam (7). The partial beams (19) are guided onto the machining plane (8) in a crossed manner and with an offset from one another in such a way that an extended laser focus (18) is formed. The radiation intensity distribution of the superposed partial beams (19) in the machining plane (8) along a line perpendicular to the seam joint respectively has a maximum at the end regions thereof. As a result thereof and as a result of the spatially extended region of high radiation intensity on both sides along the seam joint compared to the prior art, there is, firstly, an improvement in the edge connection and hence in the quality of the seam joint and, secondly, an increase in the process efficiency.

    摘要： A method of brazing two metal components (8, 9) comprises the following operating steps : prearranging a first metal component (8) provided with a connection end (8') and a second metal component (9) provided with a connection portion (9'), with at least the first component (8) of tubular shape, arranging the first component (8) of tubular shape with its connection end (8') facing the connection portion (9') of the second component (9), defining with the latter a junction slit (21), prearranging a bead (11) of filler material on the mouth of the junction slit (21), irradiating at least one fraction of the connection end (8') of the first component (8) and/or at least one fraction of the connection portion (9') of the second component (9) with at least one laser beam (12), defining thereon an impact area (13) that is outside with respect to the bead (11), in a manner such that the laser beam (12) does not directly hit the bead (11) itself, transmitting, via conduction, thermal energy from the impact area (13) to the bead (11), and melting the filler material, in which the thermal energy, transmitted via conduction to the bead (11), at least partially melts the filler material which consequently penetrates via capillarity into the junction slit (21).
