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.

A system includes a first tubular member comprising a first polymer and a second tubular member comprising a second polymer. The first tubular member defines a lumen configured to receive at least a portion of the second tubular member therein to define a joint region. The system further includes a compression sleeve configured to receive at least a portion of the first tubular member at the joint region and an energy source comprising a fiber laser configured to deliver energy to the joint region to thermally weld the first tubular member to the second tubular member. In some examples, the energy includes a wavelength of radiation transmittable through the compression sleeve and the first tubular member, and absorbable by the first tubular member and the second tubular member.
