  • Patent number: 10220440
    Abstract: A method of manufacturing a valve body having one or more corrosion-resistant internal surfaces. The method involves performing a casting process, which includes pouring a first material into a mold box, to produce a valve body casting made of the first material. During the casting process, a layer of a second material is formed on one or more internal surfaces of the valve body casting, the second material having a higher corrosion resistance than the first material, by: (1) applying, with an additive manufacturing technique, the second material to one or more external surfaces of a core, and (2) inserting the core into the mold box. A portion of the first material binds to the second material on the one or more external surfaces of the core while the first material is poured into the mold box.

  • Patent number: 10220443
    Abstract: The invention relates to a method for producing a steel shaped body, particularly, for example, a component for common rail fuel injection valves, comprising the method steps of: forming a powderous composition based on iron oxide, from oxide particles, with the addition of carbon and micro-alloy elements so as to adjust a bainitic microstructure; heating the powderous composition to a sinter temperature; reducing the shaped body obtained by sintering; and cooling the sintered shaped body to room temperature. As a result, from the three essential state phases in a state diagram (10), specifically the ferrite-perlite state range (11), the bainite state range (12) and the martensite state range (13), preferably the bainitic state phase is formed in a medium temperature range by the ferrite-perlite state range (11) being shifted to longer cooling periods and the martensite state range (13) being shifted to lower temperatures.

  • Patent number: 10220464
    Abstract: The present invention improves the stability of arc welding carried out by cyclical repetition of forward feed and reverse feed of a weld wire. An arc welding control method includes repeated forward feed and reverse feed at a weld wire feed rate, according to a prescribed cycle and a prescribed amplitude, and generation of short-circuit time intervals and arc time intervals to carry out welding, wherein the feed rate cycle and/or the amplitude are set automatically on the basis of the average feed rate and the welding rate, or the wire deposition amount per unit of weld length. Further, in the event that the amplitude has changed, feedback control of the forward feed-side shift amount is carried out in such a way that the average value of the feed rate is constant. In so doing, the feed rate cycle and amplitude are always set to optimal values.

  • Patent number: 10220471
    Abstract: An additive manufacturing system wherein a gentle sintering run on heat-fusible particles is followed closely by a selective laser melting run. The laser sintering run slightly sinters the particles and causes the particles to adhere to each other, but not necessarily deform and lose their original shape. The particles become connected via bridges between each other, which holds them in place. During the laser melting run, the powder melts in place, with minimum particle ejection or mobility, since the particles form a network of connected particles.

    Abstract: Laser processing device and method that stores characterization information representing specifics of a specific laser used for processing a material and forms a model to control the laser based on the laser performance specifics. This control sets a spacing between leading edges of sequential pulses of optical energy output by the laser, that when output by the laser, creates a laser power output with a consistent amount of pulse overlap between the sequential pulses, e.g., 50% overlap. This control is specific to the specific laser and creates a very consistent processing using the laser, e.g., a cut.
