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 connecting first and second plastic parts by a laser transmission bonding wherein the first plastic part absorbs laser light and the second plastic part is made of transparent plastic. The method includes the following steps: positioning the first plastic part in a first tool, positioning the second plastic part in a second tool so that the first plastic part and the second plastic part are spaced from each other thereby preventing mutual heat exchange between the parts, directing laser light through the second plastic part onto a connection zone of the first plastic part whereby the first plastic part is heated at least within the connection zone, after heating the first plastic part, moving the second plastic part into contact with the first plastic part, so that the second plastic part is firmly bonded to the first plastic part.

The present invention discloses a device for producing a reinforcing structure, which comprises a strip that is fibre-reinforced and comprises thermoplastic material, on the surface of a moulding. The device is characterized in that it is designed such that the laser diode array directly irradiates the heating-up area of the strip and/or the heating-up area of the surface of the moulding or of the already formed reinforcing structure, wherein the laser diodes of the laser diode array are formed as surface emitters.

The present invention relates to a device for producing a reinforcing structure, which comprises a fiber-reinforced strip having a thermoplastic material, onto a molded body surface. The device is characterized in that emission direction vectors of at least two laser diodes of a laser diode array are aligned in a non-parallel manner to one another and are directed toward one another in the direction of a heating surface of the strip and/or the molded body surface.

Method of manufacture of an automotive light comprising the steps of providing a container body delimited by a first perimetral profile, providing a lenticular body, internally delimited by a second perimetral profile and externally by an outer edge corresponding to said second perimetral profile, wherein the container body acts as an absorbent element of the light beam and the lenticular body acts as a transmission element of the light beam, providing optical devices for changing the divergence of the portions of laser beams in output from the fibers, so as to collimate them overall along at least one predetermined optical axis. The method further comprises the steps of directing on a critical portion of the welding interface at least a first laser beam emitted by a respective fiber lying on an optical plane incident with said critical portion of the welding interface.

A method for producing a component from two or more sub-components includes the steps of: producing each of the sub-components using an additive manufacturing process in which a resin, which is radiant-energy-curable, is partially cured using a selective application of radiant energy, wherein each sub-component includes a joint surface in which the resin is partially cured which is cured to a lesser degree than the remainder of the respective sub-component, so as to leave the joint surfaces in a condition suitable for bonding; assembling the sub-components with their respective joint surfaces in mutual contact; and performing a secondary cure of the partially-cured resin at the joint surfaces using an application of radiant energy, so as to further cure the partially-cured resin and bond the sub-components to each other, thereby forming the component.

A water-using household appliance, in particular a household dishwashing machine, includes a wall which is made from a metal material, and a device which is made from a plastic material and fixedly connected to the wall by a laser weld.

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.
