<p>The invention relates to a welding device for the weld-assembly of first and second parts along a weld joint, said parts defining therebetween a sealing surface. The device comprises: a supporting means (2) which can be used to move the device along the weld joint; at least one welding means (4) co-operating with the supporting means (2) so as to be maintained at a distance from the weld joint; and automatic command and control means, in particular for use with the supporting means (2). The at least one welding means is mounted on a single supporting element (3) oriented substantially parallel to the sealing surface. In addition, the device comprises: a first motorised actuator (5) secured to the supporting movement means (2) and provided with a first projection (51) co-operating with an open housing (61) in a first end face of the single supporting element (3); and a second motorised actuator (6) secured to the supporting means (2) and provided with a second projection co-operating with an open housing in a second end face of the single supporting element (3), such that the first and second projections can be moved in a plane substantially perpendicular to the sealing surface and generate the controlled movement of the supporting element (3) of the welding means (4).</p> |
