    • PROBLEM TO BE SOLVED: To provide a connecting structure for two pipes made of different metals capable of ensuring the fluid sealed connection of two pipes, the connecting structure being simplified by the use of a bonding agent layer laid in the connection part. SOLUTION: The connecting structure for two dissimilar pipes consisting of metals having different coefficients of thermal expansion, whereby the connection ends of the pipes are put in the fluid sealed connection. The connection ends 1 and 2 are fitted to each other telescopically in order to form an overlapping region 3, where the bonding agent layer 4 is formed between the two connection ends 1 and 2 in the overlapping region 3, and the connection ends 1 and 2 are fitted to each other telescopically and pre-stressed in the radial direction at 20°C approximately.

    • A method for cutting a wound hose (1), made form mutually engaging windings (11, 12, 13, 14) of a metallic tape (2), with the wound hose (1) being welded in a predetermined axial area (10) and then cut within the area (10) essentially in a plane (6) extending radially, with the wound hose (1) being axially compressed in the predetermined area prior to welding such that in the area (10) a mutual contacting of the windings (11, 12, 13, 14) occurs. The welding is performed along a predetermined number of windings (11-14) in the area (10), and the welding energy required for welding the windings is introduced via the area of the winding hose into it. Additionally, an accordingly produced wound hose (1) is provided and a device suitable for its production.
    • 一种用于切割由金属带(2)相互接合的绕组(11,12,13,14)制成的缠绕软管(1)的方法,其中缠绕的软管(1)被焊接在预定的轴向区域(10)中, 然后基本上在径向延伸的平面(6)内在区域(10)内切割,在被焊接的软管(1)在预定区域中被轴向压缩,使得在区域(10)中绕组的相互接触 (11,12,13,14)。 焊接沿着区域(10)中的预定数量的绕组(11-14)进行,并且焊接绕组所需的焊接能量通过绕组软管的区域被引入其中。 此外,提供相应地生产的卷绕软管(1)和适于其生产的装置。
