Method for joining a fluid conduit and a connection hub. There is provided a method for joining a fluid conduit 2 and a connection hub 7, wherein a fluid 2 conduit is provided having an at least partially transparent end section 1. Also provided is a connection hub 7 comprising a hub cavity 9 having a shape complementary to a shape of the end section of the fluid conduit 1. The end section of the fluid conduit 1 is at least partly introduced into the hub cavity 9 through an opening in the hub, wherein a contact interface between at least a lateral wall part of the end section 1 and a hub cavity 9 wall is established. The method includes heating a target zone 27 in the contact interface, for joining the fluid conduit 2 and the connection hub 7 at the target zone 27, by directing a light beam 29 across the at least partially transparent end section 1 of the fluid conduit 2 from a side of the fluid conduit 2 which is opposite a side of the target zone 27.

A method for producing a composite body from at least two partial bodies, at least one of the partial bodies being produced in an additive manufacturing process, includes exposing the at least two partial bodies to a solvent atmosphere, so that one surface of the partial body is smoothed. The at least two partial bodies are placed in the chamber in such a way that they touch at least one joining surface and that the solvent atmosphere creates a material connection between the at least two partial bodies on the at least one joining surface.

The present invention relates to a wind turbine blade and a method for its manufacture. A lower shell part and an upper shell part are provided, each shell part having a leading edge and a trailing edge. A first shear web and a second shear web for connecting an inner surface of the lower shell part with an inner surface of the upper shell part are provided. The first shear web and the second shear web are connected by a first distance member in a chordwise direction. The first distance member is arranged for accommodating a variable chordwise distance between said first shear web and said second shear web. The first shear web and the second shear web are placed in the lower shell part and the upper shell part is mounted.

A method of making a wind turbine blade (10) having a shear web (20, 22) bonded between first and second half shells (16, 18) is described. The method involves providing a web locator (40) on an inner surface of a half shell. The web locator has a fixed portion (42) and a spring portion (44) extending from the fixed portion. The spring portion is moveable relative to the fixed portion between compressed and relaxed states.

To provide a balloon catheter and an apparatus and method for manufacturing the balloon catheter, whereby the degree of welding can be appropriately adjusted and the balloon catheter can be formed so as to have a desired surface profile suitable for various uses including medical use. With a shaft 14 inserted through a catheter tube 30a inserted into an end portion 28b of a balloon and also with a pressure tube 32a fitted around a welding section where the end portion 28b of the balloon 28 is lapped over the catheter tube 30a, the shaft 14 is heated by emitting laser light from a laser radiation unit 8 to the welding section while the shaft 14 is rotated by a chuck, to weld the welding section.

A drive shaft includes a first shaft member made of metal, a tubular member made of CFRP, and a first exterior sleeve. The first shaft member is capable of being attached on one end side thereof to a first constant velocity joint, and has a first serrated part on which serrations are formed on another end side thereof. The tubular member is formed with a first fitting part fitted externally over the first serrated part. The first exterior sleeve covers the first fitting part by being disposed to extend over outer circumferential surfaces of the first shaft member and the tubular member. A film provided with a bonding assistance region and an adhesive are interposed between the outer circumferential surface of the tubular member and the inner circumferential surface of the first exterior sleeve.

A resin joint 20 includes an outer cylinder 21 molded by a resin material capable of transmitting laser light and an inner cylinder 22 disposed facing the inner peripheral surface of the outer cylinder 21. An annular protrusion 22b that protrudes in the radial direction and extends in the circumferential direction is formed on the inner peripheral surface of the outer cylinder 21 or the outer peripheral surface of the inner cylinder 22. The axial end of the resin tube 10 is inserted into an annular space 30 and is deformed in the radial direction following the annular protrusion 22b, and a region deformed in the radial direction has a surface that is in contact with the inner peripheral surface of the outer cylinder 21. The inner peripheral surface of the outer cylinder 21 and the outer peripheral surface of the resin tube 10 are laser-welded.

Disclosed is a liquid line improved in terms of effective producibility with a high level of process reliability and quality assurance, said liquid line comprising at least one corrugated hose and at least one connection piece for connecting the liquid line to a further component, wherein the corrugated hose and the connection piece are produced from plastic and are connected to one another via at least one welded connection, wherein the welded connection is produced by means of a laser welding process, wherein the welded connection is tight at least up to a defined operating pressure in the liquid line and wherein a stop is formed in the connection piece and defines an axial end position of the corrugated hose in the connection piece.
