A method of bonding materials may comprise defining a bond interface between two materials in a cure zone on a surface of an object and heating the bond interface with sound waves. Heating the bond interface may include applying ultrasonic sound waves to the bond interface.

A composite assembly with a laminate of fibre plies impregnated with a laminate matrix material is disclosed having pad of fibre plies impregnated with a pad matrix material, and a part with a body with protrusions which extend from the body and penetrate at least some of the fibre plies of the pad. The pad is bonded to the laminate by a stepped lap joint or a scarf joint. The assembly is manufactured by pressing the protrusions into the pad, and after the protrusions have been pressed into the pad, curing a pad matrix material impregnating the pad, and bonding the pad to the laminate.

The present invention relates to an apparatus and method for joining a longitudinal seam in a tube, to an apparatus and method of joining a longitudinal seam in a tube in a borehole, to an apparatus and method of repairing a tube and to a pig. In an aspect an apparatus is provided for joining a longitudinal seam in a tube. The apparatus (200) includes a spool (202) for progressively unwinding a coiled member (10) into an extended form (12). The member (10) transitions from a flat form when coiled (11) to a slit tube form when extended (12), in which form the member is resiliently biased. A joining device (214) is positioned downstream of the spool arranged to provide energy to a portion of the member in its extended form to cause heating so as to progressively join together the longitudinal edges of the slit tube as the member passes the joining device. A longitudinal seam (20) is thereby formed in the tube.

A system and method directed to displaying images and presenting the data from the phased array ultrasonic testing (PAUT) inspection of a plurality of welded joints within a welded object. The system includes an engine comprising memory, a graphical user interface (GUI), an export module, a transformation module, and a merger module each operably coupled to one another. The export module is used to extract images and data from the PAUT inspection of the welded joints. The exported information is used by the transformation module to create a multi-dimensional representation of the PAUT inspected welded joint for each joint. The merger module combines the information from the export module and the transformation module into an evaluation report for each PAUT inspected welded joint and assembles the evaluation report into a master report for analysis. The system may be communicatively coupled over a network using a network interface.

The present invention relates to a method and to a device for assembling together two tubes (1, 2) comprising a tubular junction sleeve and an internal pipe liner tube made of thermoplastic materials by laser welding two contact surfaces of revolution (1-1, 2-1) pressed one against the other at the ends of the tubular sleeve of said liner tube overlapping coaxially.

A method of forming a structural web for a wind turbine blade comprises providing a web member having a web portion and a flange portion extending away from each other, where 5 a heel of substantially curvilinear form is located between the web portion and the flange portion. A planar flange extender comprising a cured composite material is arranged together with the web member with the flange extender positioned adjacent to the flange portion so that a portion of the flange extender projects past the heel and away from the web portion. The flange extender is integrated with the web member in a resin matrix, or 10 with an adhesive, to form the structural web. A structural web and a wind turbine blade comprising the web is disclosed.

A method for testing the integrity of a stack during ultrasonic welding, includes the steps of: (i) ultrasonically welding two or more work pieces with a stack, the stack including a convertor and a horn; (ii) measuring a frequency profile based on a vibration of the horn during the welding step; and (iii) comparing the measured frequency profile to a standard frequency profile to obtain an error rate, the error rate being indicative of a difference between the measured frequency profile and the standard frequency profile. A system employing the aforementioned method is also provided.

Devices, systems, and methods of improving paste flow during the manufacture of wind turbine blades are provided. An apparatus for applying adhesive to a composite structure (e.g. wind turbine blade) comprises a paste shoe having a top surface with an aperture to receive a supply of adhesive, and two legs extending downwardly from the top surface and configured to engage a surface of the composite structure to define an interior volume within the paste shoe. A transport mechanism (e.g. wheels, treads) are disposed on each leg to move the paste shoe relative to the composite structure while adhesive is dispensed within the interior volume. A force applicator, applies a force to the paste shoe to maintain a constant interior volume and thus a uniform bead of paste is applied to the composite structure.

A device and method for checking an integrity of a glue joint that connects one portion of a body box and a body skin are provided. The body box and body skin connected by the glue joint define an inner volume therebetween. The method includes arranging at least one ultrasound sensing device in the inner volume; emitting a pressurized directional air jet opposite a predetermined area of the glue joint; recording a noise level detected by the ultrasound sensing device in the inner volume; and determining an integrity defect in the glue joint according to the recorded noise level.

A device (20) for installing a tubular junction sleeve inside a pipe (1), having a mandrel (20a) of longitudinal axis (XX) supporting on its surface at least a first peripheral chamber (21) having a wall (21a) that is radially expandable by inflation. The first wall including at least one electrical connector (21b) suitable for being connected to one end of said heater wire. The connector being connected to an umbilical (24) including at least a compressed air feed duct for inflating said the first chamber and an electrical power supply duct connected to the electrical connector. The device being characterized in that the mandrel supports on its outer surface a second peripheral chamber (22) having a wall (22a) that is radially expandable by inflation, and also a weld inspection device (23) arranged in the longitudinal direction of the mandrel.
