Abstract
A welding apparatus for a fibre reinforced resin based material comprises an elongate flexible heat conductive strip and an elongate heat sink extending around at least a portion of the perimeter of the conductive strip. The elongate heat sink is divided into a plurality of segments wherein adjacent segments can move relative to one another.
Claims19
A welding apparatus for a fibre reinforced thermoplastic resin based material, the welding apparatus comprising:
- an elongate flexible heat conductive strip;
- and
- an elongate heat sink extending around at least a portion of the perimeter of the conductive strip;
- wherein the elongate heat sink is divided into a plurality of segments;
- wherein adjacent segments can move relative to one another.
2 more elements
A welding apparatus for a thermoplastic based material, the welding apparatus comprising:
- a flexible elongate heat conductive strip and an associated heat source arranged to direct heat in a first direction to a laminate surface to be welded;
- and
- a heat sink extending laterally from the longest edges of the elongate strip and arranged to collect heat from the laminate surface and to communicate heat in a second opposing direction,
- wherein the heat sink is divided into a plurality of segments, adjacent segments movable relative to one another, so as to align in use with deformations in a thermoplastic based material to be welded.
