On production of a component, two primary pieces must often be fixed together to give one piece. In order to achieve the above, it is important that the two pieces are oriented in a particular manner during the fixing process, which provides some difficulties. According to the invention, a plug body is fixed to the component by a mounting, whereby the position of the plug body relative to the component remains unchanged during a fixing process.

Heat treatment of alloys having elements for improving grain boundary strength is disclosed. Components directly after castings often reveal low or no transverse grain boundary strength, so that cracks do appear and decrease the yield rate. The provided measures do not lead to low transverse grain boundary strength but maintains efficient grain boundary strength, so that the yield rate of components without cracks is increased.

Prior art methods for removing a layer area of a component (stripping) lead to poor results since a removal, for example, ensues in a nonuniform manner. In addition, these prior art methods are time intensive. An inventive method for removing a layer area of a component consists of firstly treating the layer areas to be removed with a salt solution and then with acid, whereby in an intermediate or final step, the component is treated with a complexing agent.

A configuration system for a process plant uses module class objects to assist in configuring, organizing and changing the control and display activities within the process plant. Each module class object generically models or represents a process entity, such as a unit, a piece of equipment, a control activity, etc., and may be used to create instances of the object, called module objects, which represent and are tied to specific equipment within the process plant. The module class objects may represent process entities of any desired scope, which means that a single module class object may be used to configure the control and display activities of process entities of any desired scope within the process plant, instead of just at a control module level. In particular, module class objects of a large scope may be used to configure large sections or portions of the process plant, which makes configuration of the process plant easier and less time consuming. A module class object may be a unit module class object reflecting a physical unit within the process plant, an equipment module class object reflecting a physical piece of equipment within the process plant, a control module class object reflecting a control module or scheme within the process plant, or a display module class object reflecting a display routine that provides information to a user within the process plant.

An apparatus having a programmable processor and a memory for performing a plurality of user-selectable control functions includes a database for storing a plurality of items associated with each of the control functions. The items include, for each function, at least one procedure for performing an action associated with the control function and a specification of at least one state associated with the control function. The apparatus further includes software routines stored on the memory and adapted to be executed by the processor that facilitate selection of a procedure in the database, that access the database and cause performance of the selected procedure to achieve the state specified therein, and that monitor at least one resource associated with the action of the procedure and, based thereon, determine whether the specified state has been achieved.

A dynamic load balancing system is described that determines the load of resources in a hosted environment dynamically by monitoring the usage of resources by each customer and determines the number of customers hosted by a server based on the actual resources used. The system receives a performance threshold that indicates when a server is too heavily loaded and monitors the resource usage by each customer. When the load of an overloaded server in the hosted environment exceeds the received performance threshold, the system selects a source customer currently hosted by the overloaded server to move to another server.

摘要:
A method for directionally compacting a weld seam during build-up welding is provided. The method is used for the build-up welding of a component substrate that is compacted in a directional manner and comprises dendrites which extend in a substrate dendrite direction. The method parameters with respect to feed, laser power, weld beam diameter, powder beam focus and/or powder mass flow are designed such that they result in a local orientation of the temperature gradient to the solidification front, which is smaller than 45° with respect to the substrate dendrite direction of the dendrites in the substrate, wherein the relative speed is between 30 mm/mm and 100 mm/mm, and/or the power is between 200 W and 500 W, and/or the diameter of the laser beam on the surface of the substrate is between 3 mm and 6 mm, and/or the mass feed rate is between 30 mg/mm and 600 mg/mm.

A process for the directional solidification of a weld seam during build up welding is provided which includes the targeted selection of process parameters for laser welding, feeding, laser power beam diameter, and powder mass flow. The temperature gradient substantially decisive for single crystal growth during laser application welding can be set deliberately.
