Pipe element with a trimmed edge for welding onto a carrier
The present disclosure relates to a pipe element with a trimmed edge for welding onto a carrier, wherein the trimmed edge is cut from a base tube so that the pipe element can be arranged on the surface of the carrier and welded to it along the trimmed edge, wherein the trimmed edge has a first cam with which the pipe element can be placed on the surface of the carrier. It is further provided that the trimmed edge has at least one second cam with which it can be placed on the surface of the pipe element, so that an air gap remains between the surface of the carrier and the trimmed edge in a region lying between the first cam and the second cam.
1. An article of manufacture, comprising:
a pipe element with a trimmed edge that is welded onto a carrier, wherein the trimmed edge has a first cam with which the pipe element is placed on a surface of the carrier; and
wherein the trimmed edge has at least one second cam with which the pipe element is placed on a surface of the pipe element, so that an air gap remains between the surface of the carrier and the trimmed edge in a region lying between the first cam and the second cam;
wherein the trimmed edge has at least a third cam with which the pipe element is placed on the surface of the pipe element;
wherein a line of contact of the trimmed edge with the surface of the carrier in the region of the first cam has a length between 20° and 100°, and/or a line of contact of the trimmed edge with the surface of the carrier in the region of the second and/or third cams is less than 20°; and
wherein the contact in the region of the second and third cams is essentially point-shaped, and wherein the carrier is tubular in shape.
2. The article according to claim 1 , wherein midpoints of the first and second cams lie at a distance of at least 60° from one another.
3. The article of claim 1 , wherein the article of manufacture further comprises a lattice piece in which the pipe element is welded with the carrier along the trimmed edge, and wherein the carrier forms a longitudinal brace and the pipe element forms a diagonal brace.
4. The article of claim 3 , wherein the lattice piece forms a component of a construction machine or material handling machine.
