Claim 0:
1. A method for joining first and second workpieces (10),
wherein each workpiece has a joining surface (20) for joining the workpieces (10),
wherein a viscous adhesive in the form of a continuous material strand (30) is applied to a first joining surface (20), along an application track (50) that extends in an application direction (40),
wherein the application track (50) comprises a plurality of identical length units measured in the application direction (40),
wherein the continuous material strand (30) is applied to the first joining surface (20) in a plurality of alternately arranged hybrid adhesion regions (80) and adhesion regions (90) along the application track (50),
wherein the joining surfaces (20) are arranged to lie opposite one another so as to delimit an intermediate gap in which the material strand (30) is arranged,
wherein the workpieces (10) are joined to one another in the region of the material strand (30), with the aid of at least one further joining means (70) selected from the group consisting of weld connections and joining bodies,
wherein the at least one further joining means (70) is arranged in each hybrid adhesion region (80) and penetrates the material strand (30),
wherein the amount of adhesive applied in the hybrid adhesion regions (80), per length unit measured in the application direction (40), is less than the amount of adhesive applied in the adhesion regions (90), per length unit measured in the application direction (40),
wherein the material strand (30) forms a first pattern in the adhesion regions (90) and a second pattern different from the first pattern in the hybrid adhesion regions (80),
wherein the first and second patterns are formed in such a manner that the material strand is applied oscillating about a center line (55) of the application track (50), and
(a) the distance between two consecutive intersection points (65, 66) of the material strand with the center line (55) is greater in the hybrid adhesion regions (80) than the distance between two consecutive points along or intersecting the center line (55) in the adhesion regions (90); and/or
(b) the maximum deflection (67) of the material strand with reference to the center line (55) is less in the hybrid adhesion regions (80) than in the adhesion regions (90); and/or
(c) the material strand (30) has a variable strand cross-section, wherein the strand cross-section is smaller in the hybrid adhesion regions (80) than in the adhesion regions (90).
