Abstract: A welding method for welding a first component to a second component using a welding device including an upper tool mounted to an upper support for receiving the first component, a lower tool mounted to a lower support for receiving the second component as well as a preheating arrangement for preheating the first and/or the second component and a controller. A welding device in accordance with the welding method is further provided.

Abstract: A spring package for a vibration welding device includes a first longitudinal bar for a fixed connection to a frame of the vibration welding device and a second longitudinal bar parallel to and movable with respect to the first longitudinal bar as well as for connection to a tool. A first axis of the spring package extends halfway between and parallel to the longitudinal axis of the first and second longitudinal bar. A plurality of leaf springs are further provided, each connected with a first end to the first longitudinal bar and with a second end to the second longitudinal bar, wherein a second axis of the spring package extends perpendicular to the first axis as well as, in an inactive state of the spring package, parallel to the plurality of leaf springs so that a spring center line extends, in an inactive state of the spring package, parallel to the second axis in the middle of the leaf spring.
