    Abstract: Disclosed is a method for non-vacuum electron beam welding metallic materials by means of a vacuum electron beam gun and with the aid of process gas. According to the inventive method, at least one inert gas (11, 28) is used in addition to the process gas (33), said inert gas (11, 28) being used in different manners and compositions by means of an inert gas supply apparatus in the form of a nozzle configuration (2), which is arranged on the vacuum electron beam gun (1). According to the invention, a process gas (33) is used that contains helium and 40 to 80 percent by volume of nitrogen, with/without admixing hydrogen and/or oxygen, while the inert gas contains argon, helium, and optionally added oxygen and nitrogen. The inventive method and the inventive device allow for optimal process control and thus inexpensive and quality-responsive material processing.

    Abstract: An improved vehicle wheel and method for producing the same, the vehicle wheel including a rim including at least an inboard portion, generally axially extending well, and an outboard portion, and a disc including at least an inner annular wheel mounting portion and an outer annular portion. The disc is joined to the rim by a non-vacuum electron beam welding process to produce a vehicle wheel including an inboard tire bead seat retaining flange, an inboard tire bead seat, a well, an outboard tire bead seat, and an outboard tire bead seat retaining flange. The method for producing the vehicle wheel includes the steps of: (a) providing a rim including at least an inboard portion, generally axially extending well, and an outboard portion; (b) providing a disc defining a disc axis and including at least an inner annular wheel mounting portion and an outer annular portion; (c) initially joining the rim and the disc together by a plurality of tack welds; and (d) joining the rim and the disc together by a non-vacuum electron beam welding process to produce the vehicle wheel, the non-vacuum electron beam welding process joining the rim and the disc together by a single continuous at least 360 DEG weld.

    Abstract: The invention relates to a method for forming a three-dimensional article through successive fusion of locations of a powder bed. The method comprising: providing a model of said three-dimensional article; applying a powder layer on a work table; determining a maximum scan length of an energy beam; directing said energy beam from a first energy beam source over said work table with constant energy causing said first powder layer to fuse in first selected locations according to said model to form a first cross section of said three-dimensional article, wherein locations with a shorter scan length than said maximum scan length is provided with a time sink before and/or after said scan line so that the time period between each two adjacent scan lines is constant throughout the manufacture of said three-dimensional article.
