ABSTRACT:
A hindgas implement for protective gas coverage of the root of a welded seam that may be fixed to work pieces to be welded by means of vacuum chambers (11, 13) that are emptied of air via pipe branches (25). After that protective gas is fed to the root of the welded seam via a diffusor (19) and is withdrawn via outlets (21, 23). By means of this, hindgas coverage can also be achieved in welding together of major, extensive work pieces made up of plate as there is no dependence on free edges on which to clamp the hindgas device.
