Abstract: The rail guide (6) for a mobile welding, cutting- or handling equipment for carrying and leading processing objects at large construction conservations along a contact contour (2) of two elements of a pipe-to-pipe-intersection, comprises two guide surfaces lying parallel to a guide direction with an expansion in a small thickness direction with rectangular or V-shaped sectional shape of the guide surfaces and rectangular lying along the guide direction. Notches are arranged between the guide surfaces in a fixed division to a positive drive from the rail guide. The rail guide (6) for a mobile welding, cutting- or handling equipment for carrying and leading processing objects at large construction conservations along a contact contour (2) of two elements of a pipe-to-pipe-intersection, comprises two guide surfaces lying parallel to a guide direction with an expansion in a small thickness direction with rectangular or V-shaped sectional shape of the guide surfaces and rectangular lying along the guide direction. Notches are arranged between the guide surfaces in a fixed division to a positive drive from the rail guide. The rail guide: is attached at both tubes involved at a connection in a normal interval to its coat area on the one hand and to the contact contour on the other hand; is fixed at the tube involved at the connection, which requires no joint preparation; is not universal but dimensioned for each pipe-to-pipe intersection to be made and divided into an individual, comparatively short, easy to handle manually rail segments (7). The rail segments are stiff, inflexible, in two dimensions curved elements, which possess at its ends cardanically working joints, whose first articulated axis (13) and second articulated axis (14) stand in right-angled to each other, where a neutral fiber of the rail segments is orthogonally intersected. The rail segments are connected with a holder arm that is arranged between a pipe and the rail segment and extends itself in a direction turned away by the contact contour of the rail segments. Each holder arm is encompassed between its ends of a fastening block and is produced with a pressure screw by the fastening block over the holder arm of a force effect in a fixed point on the rail segment toward the pipe. The rail segments are releasably joined over articulations with comparatively small angle mobility, where an arc shaped joint lobe is introduced at the rail segment in associated an arc shaped notches of the rail segment, which is attached and fixed with screws guided in an oblong hole. The cardanically working joints are formed as conventional designed, positive pivots and/or firmly bonded joints. A tolerance balance is feasible by a part of the holder arms, in which a slider on the holder arm is displaceably arranged over an adjusting spindle, where the slider is adjustably connected with a coupling rod, which possesses ball joints at its two ends connecting with the fastening block. The rail segment is adjustable in its layer to the contact contour. The connection of the fastening blocks is fixed with the pipe.
