摘要

Joining device comprises a burner shank (3), where at its distal end a burner tip (2) is provided for providing the required heat for producing a material connection, and a suction nozzle connected to a suction device, through which exhaust air within the region of the burner tip, at which the resulting pollutants and/or flue gas are at least partially sucked out and are dischargeable through an exhaust air duct (7), where the suction nozzle (4) surrounds the burner shank, and an annular gap (5) with a greater constant cross-section is provided between the burner shank and aspiration sleeve.
