Arrangement for connecting two rail segments

1. An arrangement of two rail segments comprising a plurality of holding elements disposed on each rail segment and at least one connecting element in contact with one of the holding elements of each rail segment, by which connecting element the rail segments can be connected to each other at end faces of the two rail segments, wherein each rail segment includes a pair of opposing outer sides, and wherein each outer side includes a side surface that extends between a pair of longitudinal grooves, wherein at least one holding element is disposed within each longitudinal groove and wherein each holding element is attached to the respective rail segment via a weld seam with the weld seam having an end that extends away from the holding element so that the end of the weld seam ends in a region of the side surface outside the holding element on the rail segment, wherein each weld seam includes a longitudinal portion extending at the respective longitudinal groove and wherein the end of the weld seam extends from the longitudinal portion and is linear and deviates at an angle from the longitudinal portion of the weld seam, and wherein each side surface of each rail segment includes a flat profile, and wherein the ends of the weld seams extend out of the longitudinal grooves as far as the flat profile on each rail segment.

2. The arrangement as claimed in claim 1 , wherein the length of the end is 10 to 30 mm.

3. The arrangement as claimed in claim 1 , wherein the end is remote from an end face of the holding element.

4. The arrangement as claimed in claim 3 , wherein each holding element comprises two long sides, and wherein for each rail segment the weld seam extending in the longitudinal direction is disposed on one of the two long sides of the holding element, and wherein an additional weld seam extends in the longitudinal direction of the rail segment and is disposed on the other of the two long sides of the holding element, and wherein the additional weld seam includes at least one end that extends away from the holding element so that the end of the additional weld seam ends in a region outside the holding element on the rail segment.

5. The arrangement as claimed in claim 4 , wherein the weld seams on each long side of each holding element have different lengths, angles and lengths in the deviation.

6. The arrangement as claimed in claim 1 , wherein the rail segments are hollow profile rails which are composed of two profiles disposed symmetrically with respect to the vertical longitudinal middle plane, and the holding elements are disposed on the outer sides of the rail segments.

7. The arrangement as claimed in claim 1 , wherein the holding elements have a contact surface, extending transverse to the longitudinal direction of the rail segments, as a counterbearing surface for the respective connecting element, and wherein the holding elements comprise sleeves or C-groove profile pieces and the connecting element comprise screw bolts.

8. The arrangement as claimed in claim 1 , wherein the angle is 15-45 degrees.

9. The arrangement as claimed in claim 1 , wherein each holding element comprises two long sides, and wherein for each rail segment the weld seam extending in the longitudinal direction is disposed on one of the two long sides of the holding element, and wherein an additional weld seam extends in the longitudinal direction of the rail segment and is disposed on the other of the two long sides of the holding element, and wherein the additional weld seam includes at least one end that extends away from the holding element so that the end of the additional weld seam ends in a region outside the holding element on the rail segment.

10. The arrangement as claimed in claim 9 , wherein the weld seams on each long side of each holding element have different lengths, angles and lengths in the deviation.
