ABSTRACT:
Two rail sections are joined by a weld joint (5) between two rails (1,2) arranged one behind another in a lengthwise direction of a rail track (4) and a method for the production of this weld joint (5). The frontal ends (6,7) of the rails (1,2) which are facing each other are connected with one another by a filler material (8), which extends from the rail foot (32) to the rail head (30). The weld joint (5) is composed of a welding zone (22, 23, 24, 25) which connects the rail foot (32), the stem of the rail (31) and the rail head (30). The welding zones (22 to 25) are connected in a form-locking manner in the contact areas (33 to 36) immediately facing each other. Furthermore, the welding zone (22) of the rail head (30) consists of less than 15 neighbouring, molten beads (26) preferably situated one above another and approximately running parallel to each other. The welding zone (24, 25) of the rail foot (32) consists of less than 10 neighbouring, molten beads (28, 29) which run approximately parallel to each other.
