External pressure is added, so that to cause the first and second workpieces to move toward each other. The heated or molten dimples are then collapsed, and flow into the recess formed surrounding each dimple. As the /recess provides spaces or rooms for each of the collapsed dimples to flow into, the two workpieces can effectively be brought into contact and welded together throughout the joint interface, without a gap formed in between.

219 Method for attaching a resonator part and a resonator US09902852 2001-07-10 US20020005768A1 2002-01-17 Esa Mikkonen
The invention relates to a method for attaching an additional object to an object made by the process of extruding, especially a resonator body, and to the structure resulting from the application of the method. A recess is made in the pushing part (ES) of an extrusion machine, which recess is shaped like a portion of the surface of the additional object. The additional object (320), such as a portion of the inner conductor of a resonator, is inserted prior to extrusion in the said recess so that the said portion of the surface of the additional object rests tightly against the surface of the recess and the rest of the surface of the additional object remains free. In the extrusion stage, the pushing part with the additional object is pressed (F) against a bloom of a resonator body whereby the material (31c) of the bloom is pressed tight against the free surface of the additional object. When the pushing part is retracted the additional object remains attached to the body element thus formed. According to the invention, in conjunction with the manufacturing of the body element of the structure being manufactured, parts may be added to the body element without separate manufacturing steps, and the resulting bond is strong and uniform. Furthermore, in a filter manufactured according to the invention the inner conductors of the different resonators may be manufactured in different lengths.
