A tunnel for fluxless soldering, is a straight linear tunnel which contains a non-explosive gas atmosphere. The gas atmosphere includes a small portion of hydrogen or other gaseous reducing agent, sufficient to achieve a fluxing action. A process for soldering an element comprises the steps of conveying the element through a tunnel containing a non-explosive gas atmosphere substantially excluding oxygen, heating the element in the tunnel, soldering the element, and retaining the element in the gas atmosphere of the tunnel until solder on the element has solidified.

Tunnel pour soudage sans flux. Il s'agit d'un tunnel droit linéaire sous atmosphère de gaz non explosif. L'atmosphère gazeuse comprend une faible quantité d'hydrogène ou un autre agent réducteur gazeux, suffisant pour permettre l'action du flux. Une méthode de soudage d'un élément comprend les étapes de la mise en place de l'élément dans un tunnel sous atmosphère gazeuse non explosive, c'est-à-dire sans oxygène, du réchauffement de l'élément dans le tunnel, du soudage de l'élément et du maintien de l'élément dans l'atmosphère gazeuse du tunnel jusqu'à la solidification de la soudure sur l'élément.
