摘要:
A gas turbine engine hot gas component repair method for defects that do not extend through the thickness of the component is provided. First defects are removed by machining a cavity in the surface of a component. Coupons, fittable within the cavities are manufactured, are for example coated with brazing medium on an inner surface and then joined to the component by joining means such as laser metal forming. The joint holds the coupon during later heat treatment, thereby eliminating a need for holding aids. Before heat treatment, a further brazing medium can be applied to the surface of the coupon overlapping onto the component. A single heat treatment, brazing the coupon to the component and, brazing the brazing medium to the outer surface of the coupon can, then be used to complete the repair.

摘要:
A facility for the thermal treatment of workpieces has a processing or heating chamber and at least one transport device, extending essentially completely through the processing or heating chamber, with which the workpieces to be treated can be transported through the processing or heating chamber. At least two processing or heating levels are hereby located on top of one another in the processing or heating chamber, with each processing or heating level having at least one separate transport device. This type of facility can preferably be used as a soldering facility, particularly a reflow soldering facility, or as a facility for the hardening or drying of plastics or adhesives.

The invention pertains to a device for determining the relative position in the X-Y plane between two essentially flat elements that are spaced apart in the Z-direction and are essentially arranged on top of one another, wherein said device features at least one optical sensor that is arranged between the elements and is able to sense at least two points of the mutually facing surfaces of the elements, as well as an evaluation unit, in which the images of the points can be evaluated with respect to their relative position in the X-Y plane. In this case, the optical sensor features at least one line sensor that can be displaced relative to the two elements in such a way that the mutually facing surfaces of the elements can be optically scanned at least in sections in the manner of a scanner.
