Method for joining a fluid conduit and a connection hub

A method for joining a fluid conduit and a connection hub, comprising:

• providing a fluid conduit having an at least partially transparent end section,
• providing a connection hub comprising a hub cavity having a shape complementary to a shape of the end section of the fluid conduit,
• introducing the end section of the fluid conduit at least partly into the hub cavity through an opening in the hub and establishing a contact interface between at least a lateral wall part of the end section and a hub cavity wall, and
• heating a target zone in the contact interface, for joining the fluid conduit and the connection hub at the target zone, by directing a light beam across the at least partially transparent end section of the fluid conduit from a side of the fluid conduit which is opposite a side of the target zone,
• wherein a plurality of light beams are directed across the at least partially transparent end section of the fluid conduit for heating a plurality of respective target zones, each light beam of the plurality of light beams being directed to an associated target zone and being directed across the end section from a side of the fluid conduit which is opposite a side of the associated target zone, and
• wherein the plurality of light beams extend in a biconical plane.
