Guide device for guiding a welding carriage for welding of a pipe surface, comprising:
- a flexible elongate body provided with a guide for the welding carriage, said flexible elongate body having an underside;
- a tensioner for tensioning the flexible elongate body around the pipe;
- wherein the flexible elongate body is provided on said underside with a plurality of spacers comprising a spring mechanism;
- wherein a spacer of said plurality of spacers comprises a cup-shaped spring holder having a first open end directed towards the flexible elongate body and a second end remote from the flexible elongate body in the form of an annular foot having an annular contact surface for making contact with the pipe surface;
- wherein the spring mechanism of the spacer is provided in the cup-shaped spring holder;
- and acts between the spring holder and the flexible elongate body.
Guide system for guiding a welding carriage for welding a pipe surface, said guide system comprising:
- a welding carriage;
- a metal band provided with a guide for the welding carriage;
- a tensioner for tensioning the metal band around the pipe surface;
- wherein the metal band is provided on an underside thereof with a plurality of spacers;
- each spacer of said plurality of spacers being associated with a spring mechanism, and comprising a cup-shaped spring holder, having a first open end directed towards the metal band and a second end remote from the metal band in the form of an annular support foot having an annular contact surface for making contact with the pipe surface;
- wherein the spring mechanism is provided in the cup-shaped spring holder;
- and acts between the spring holder and the metal band.
