  • Method and a device for the welding of two parts to be joined made of thermoplastic synthetic materials along a weld seam by means of laser
    Patent number: 10300664
    Abstract: A system for welding two parts to be joined made of thermoplastic synthetic materials along a weld seam by a laser operating with a laser beam having a beam direction within an operating field by a control method with control data corresponding to the weld-seam course to be produced, including a beam dimension in the region around its focus causing the welding, which is smaller in the joint plane than the target width of the weld seam to be produced, and is dependent upon the angle of incidence of the laser beam on the joint plane and/or upon the position of the focus relative to the joint plane, is displaced in a first movement component in a principal forward-feed direction along the track of the weld-seam to be produced, in a second, oscillating movement component superimposed over the former to cover the weld-seam width transversely to the principal forward-feed direction with an oscillation amplitude value, and is adjusted with a control method in its oscillation amplitude width in inverse dependence upo
