Patent

CA 2445474

A method and a device for the longitudinal welding of profiles (25, 13) are provided in which a profile (13) that is to be provided with a weld seam (22, 23) is guided through a welding device (1), and in the welding device (1) a welding head (14, 15) produces a weld point (20, 21) on the profile (13), in order to manufacture a weld warn (22, 23). The profile movement is braked at selectable intervals from an essentially constant production speed down to the point at which the profile (13) is at a standstill, and is subsequently accelerated back to the production speed, while the application of welding energy to the profile (13) is switched off below a threshold transport speed. in order to avoid a gap in the resulting weld seam (22, 23), according to the present invention a welding head control system is used, with the aid of which the location of the weld point (20, 21) is moved in the direction of transport (12) of the profile (13), beginning from an initial point, each time the profile (13) is at a standstill, the weld point (20, 21) being moved back to the initial position, against the direction of transport (12) upon restarting of the transport movement, after the threshold transport speed has been reached.

Il s'agit d'une méthode et d'un dispositif de soudage longitudinal de profilés (25, 13) dans lequel un profilé (13) présentant un joint de soudure (22, 23), est guidé à travers un dispositif de soudage (1). Dans ce dispositif (1), une tête de soudage (14, 15) produit un point de soudure (20, 21) sur le profilé (13), afin de créer une voilure de la soudure (22, 23). Le mouvement du profilé est freiné à des intervalles sélectionnables, d'une vitesse de production en grande partie constante, jusqu'au point où le profilé (13) reste immobile. Ensuite, sa vitesse s'accélère de nouveau jusqu'à la vitesse de production, tandis que l'application du soudage au profilé (13) est coupée, en deçà d'une vitesse au seuil de transport, afin d'éviter un écart dans le joint de soudure résultant (22, 23). Conformément à la présente invention, il est fait appel à un système de commande de la tête de soudage, grâce à laquelle l'emplacement du point de soudure (20, 21) est déplacé dans le sens de transport du profilé (13). En commençant à un point initial, chaque fois que le profilé (13) est immobile, le point de soudure (20, 21) est ramené à la position initiale par rapport au sens du dispositif de transport (12), au réamorçage du mouvement de transport, après que la vitesse seuil de transport ait été atteinte. Voir Figure 1.
