The angular connection is for tube components and involves first and second connecting devices working in conjunction with each other and formed from the walls of the tube components. A computer-controlled tube laser machine (1) is used, with which tube components (7) can be cut. It has a clamp station (2), with a through passage (4), a support (3), with a through passage (6) and a transport device for moving the tube in a specific direction (A). In the clamp station and support are devices for rotating the tube in a second specific direction (B). On the downstream side of the support is a laser head (6), which is displaceable in further directions (C,D). The laser head is controlled by the computer in order to cut into the tube at the desired location. In this way, a V-shaped opening (8) is formed between two tube parts (9,10). The under side of the tube thus forms a kind of hinge (11). With the laser head, not only the opening can be formed, but also the walls can be cut into or cut out. On the edges limiting the opening, connecting/coupling devices can be formed.
