    摘要: The invention concerns a friction stir welding method according to which the workpieces (2, 3) to be welded are positioned on a worktable (7) and by means of clamping means (5, 6) clamped to one another and/or to the work-table during the welding. A rotating welding means (12, 13) is arranged to move along a joint between the work pieces while being pressed against said workpieces during the welding. Additional heat is supplied to the joint prior to and/or during the welding operation, in excess of the frictional heat generated in the joint from the rotation of the welding means and of any other heat hat may be supplied to the joint in any other manner by the welding means. The invention likewise concerns an apparatus for friction stir welding, comprising a heat element (70) for supply of additional heat to the joint prior to and/or during the welding operation, in excess of the frictional heat generated in the joint from the rotation of the welding means and of any other heat that may be supplied to the joint in any other manner by the welding means.

    摘要: Method, arrangement and computer program product in a base station for transmitting two USF values and two data blocks to a terminal. The base station and the terminal are comprised within a wireless communication network. The two USF values are to be sent across the first data block and the second data block. The first data block and first parts of the two USF values are modulated with a first modulation technique and the second data block and second parts of the two USF values are modulated with a second modulation technique. The modulated data blocks and USF parts are transmitted to the terminal. Further, a method, an arrangement and a computer program product in a terminal for receiving USF values and data blocks from a base station are described. In addition, a method, an arrangement and a computer program product in a control node are described.
