A method for analysing a bonding between two aeronautical parts. The method includes the steps of a) applying a release agent to a first surface to be bonded of a first part and to a second surface to be bonded of a second part, b) applying an adhesive to at least one of the first and second surfaces and positioning these surfaces on top of each other, the adhesive forming an adhesive film after polymerisation, c) separating the parts from each other and removing the adhesive film in one piece, d) analysing the adhesive film. The invention also relates to a method for bonding two aeronautical parts.

A first plastic part is fixtured in a first fixture, and a second plastic part is fixtured in a second fixture for welding to each other. The first plastic part can be independently moved relative to the second plastic part in each of three directions: 1) linearly in a direction parallel with a z-axis, 2) linearly in a direction parallel with an x-axis, and 3) circularly in a circular arc about an axis parallel with a y-axis.

Simultaneous laser welding equipment of a vehicle light including at least a plurality of laser sources suitable for emitting light beams, a plurality of optical fibres associated, at the input ends to the at least one laser source and transmitting the light beams. A light guide is provided with at least one hollow seat that delimits a continuous perimetral contour, counter-shaped to the weld interface. The light guide comprises diffusion elements that pass through the perimetral contour of the seat of the light guide internally, so as to intercept and influence the light beams that propagate inside the seat and that are shaped to expand the light beams along a direction substantially tangent to the curvilinear abscissa defining the perimetral contour, before it projects from the light output wall and/or at the latter.

The application relates to a method for producing a double-walled pipe (1) and a pipe (1) of this type, having an outer pipe (3) which is press-fitted with an inner pipe (2) consisting of a corrosion-resistant alloy, wherein an adhesive (4) is inserted at least in regions between the outer pipe (3) and the inner pipe (2), wherein, after adhering the inner pipe (2) with the outer pipe (3), the inner pipe (2) and the adhesive layer (4) are removed at the pipe ends, and the inner side of the outer pipe (3) is plated via an integral connection with the inner pipe (2).

A system of connected elements for a motor vehicle includes: a first element which has at least one depression on a surface; a second element which is arranged on the first element in such a manner that a surface of the second element and the depression of the first element form a cavity; a filling opening which forms an access to the cavity; and an adhesive which at least partially fills the cavity and thereby adhesively bonds the first element to the second element.

A bonding apparatus includes adhesive sheet that includes a central adhesive portion adhered to a central portion of a first substrate and a bendable adhesive portion that surrounds the central adhesive portion in a plan view and that is adhered to an edge portion of the first substrate that extends from the central portion, a molding member that includes a top surface that overlaps the central portion and a side surface bent from the top surface and that has a curved shape and that supports the adhesive sheet through the top surface, a magnet member disposed on a first display surface of a second substrate that covers the central portion of the first substrate, and pressing balls disposed in the molding member. The pressing balls press fife central adhesive portion and the bendable adhesive portion by forming attractive force with magnet member.

A method for assembling a shell section of a wind turbine blade includes providing a support, the support comprising a surface having a primary surface portion configured for supporting a first component and a secondary surface portion configured for supporting a second component. The method also includes arranging a second component on the secondary surface portion such that an outer surface of the second component is facing the secondary surface portion. The method further includes arranging a first component on the primary surface portion such that an outer surface of the first component is facing the primary surface portion, and such that a first primary joint surface of the first component is facing a second joint surface of the second component. Arranging the first component includes applying a force to the first component to force the outer surface of the first component towards the primary surface portion and the first primary joint surface towards the second joint surface.

A method of induction welding a first thermoplastic composite (TPC) to a second thermoplastic composite (TPC) using an induction coil includes forming a weld interface area between the first TPC and the second TPC, cooling the first TPC with a cooling apparatus before heating by the induction coil, and inductively heating the weld interface area with the induction coil after cooling the first TPC.

A process for welding of at least two separate vehicle panels (12, 14) to form an integral part (16) for a vehicle. There is provided at least one first panel (12) including a first weld line area (18) and at least one second panel (14) including a corresponding second weld line area (19), the second weld line area (19) abutting in a weldable relationship to the first weld line area (18). The first and second weld line areas (18, 19) have at least one first weldable portion (22) and at least one second portion (24) at which welding is substantially hindered during welding attachment of the first and second panels (12, 14). The process includes applying a curable adhesive at each second portion (24), placing in a welding fixture and welding the panels (12, 14) at each first weldable portion (22) such that the panels (12, 14) are held together during curing of the adhesive.

A forming tool is used, which has a tool trough arranged in a stationary manner and a pressure bell, which can be lowered onto and lifted away from the tool trough. An arrangement is created in which a single- or multi-layer, initially flat, flexible laminate separates the trough interior from the pressure-bell interior in a pressure tight manner. A table, on which the 3-D substrate to be coated is located, assumes a lowered position within the trough interior; there is a considerable, free intermediate space (between the laminate and the 3-D substrate. A radiant-heater assembly is inserted into said intermediate space. The radiant-heater assembly has a carrier, on the top side of which radiant heaters that can be activated are attached and on the bottom side of which radiant heaters that can be activated are attached.
