Figure 5 shows a slightly modified embodiment in relation to the embodiment according to Figure 3. In Fig. 5, a coupling member in the form of a bracket 6, which is welded to the fastening member 1, is arranged on the anchoring part 5.
    The anchoring detail in Figures 3 and 5 has been exemplified by an elongated simple shape. According to the invention, anchoring details can be produced in a large assortment, in which different geometric shapes and sizes are included.
    Anchoring details according to the invention are easy to produce regardless of shape and size. The range can be expanded as needed. The fastener 1 of aluminum or stainless steel can be manufactured in any shape, for example curved, and then coated with a primer layer with subsequent coating with a material which can be welded by means of high-frequency welding.
    An example of a suitable primer is: Primer 102008-0098 with the trade name P30O (YELLOW) from Akzo Nobel Industrial Finishes AB.

With the method according to the invention, compared with hitherto known methods, significant improvements are achieved in terms of manufacturing time and manufacturing costs for construction details included in the final product and also significant time savings in connection with assembly of the final products. Figure 8 shows schematically how anchoring details according to the invention can be used for construction or assembly of constructions and components. Figure 8 shows how two anchoring details can be connected to each other by placing the connecting layers in direct contact with each other and welding them together by means of high-frequency welding. In this way, very strong joints are created. or the construction sector to streamline the assembly of car components The method is useful, for example, in the car industry in resp. building components. The fastening element 1 on a first anchoring member 5 is connected to a first component, for example by a screw joint or conventional welding joint, and a second component to be assembled with the first component is correspondingly connected to a second anchoring member, after which the two components can be joined by high frequency welding as schematically shown in figure 8. The components that can be connected in this way can of course be of many different types and in figure 8 the components have been omitted.
