摘要:
A fuel injector which includes an actuator having an electrical contact element, a plug, a fuel supply pipe, and an injection-molded housing part. The plug has a base body, an electrical connection element for an electrical connection with the electrical contact element of the actuator, and a rib which projects from the base body, the injection-molded housing part surrounding the electrical connection element of the plug and being injection-molded on the rib of the plug and the fuel supply pipe.

摘要:
A method for aligning an elongated component that is to be fitted, with at least two component segments, into two coaxial installation points (A/B; C) spaced apart from one another. In this context, the coaxiality of the component segments is checked and any existing deviation from coaxiality is measured. At least one material fusion area, limited radially and in a circumferential direction, is generated in a surface region of the component located between the component segments, at a magnitude such that as a result of the axial shrinkage ensuing upon cooling of the material fusion area, coaxiality of the component segments is produced at least within tolerable limits.

The disclosure relates to a method for clamping a lithium ion accumulator, which has a lithium ion accumulator cell stack having a top surface, a base surface opposite the top surface and a peripheral surface having four side surfaces, and at least two prismatic lithium ion accumulator cells. The lithium ion accumulator cell stack is clamped by at least one tension strap apparatus which is arranged and tensioned in the region of the peripheral surface, the ends of the tension strap meanwhile being kept free of tension. While free of tension, the ends of the tension strap are connected to each other directly or indirectly by using one or two plates, which are arranged on a side surface or two mutually opposite side surfaces of the peripheral surface. The disclosure further relates to a lithium ion accumulator and a motor vehicle having a lithium ion accumulator.

A method for laser welding super alloys is disclosed. The power of the laser (12) is controlled depending on the temperature of the welding bath and a device (10) for laser welding a super alloy, including a laser beam source (12), a process controller (30), a temperature recording unit (28) and a feed device (24) for additional materials, characterized in that the process controller (30) comprises a regulator (34), connected to the temperature recording unit (28) and the laser source (12).
摘要:
The invention relates to a method for positioning two components to be joined to each other along a common joint line. According to the invention, the two components are connected to each other by limited-length tack welds firmly connecting the two components, particularly by way of bonding, to each other. In order to obtain reliable and robust positioning of the components for tacking during the joining process, without requiring extensive production apparatuses, such as is required for the high-precision setting of the focal point of the welding laser relative to the joint line, the tack welds are designed such that they cross the joint line.
摘要:
In a laser welding method for joining a first workpiece to a second workpiece, the first and the second workpieces are brought into contact with each other in a first method step, an intended welding distortion is ascertained in a second method step, and the first and the second workpieces are welded together in a third method step as a function of the welding distortion.
