    Abstract: A method of laying a pipeline is described in which both internal and external weld passes are performed in order to weld together the pipe sections (2a, 2b). The method includes arranging a pipe section (2b) adjacent to the end (2a) of a pipeline thereby defining a circumferential joint (8) to be welded, performing an external weld pass with, for example GMAW - MIG torch (10), on the root of the joint (8) to be welded during which weld material is deposited in the root of the joint to be welded, thereby forming a root weld (4r), and then performing an internal weld pass with, for example a GTAW - TIG torch (12), on the root weld (4r) during which the root weld (4r) is melted and re-shaped. The method has particular application in relation to pipes clad with corrosion resistant alloy (CRA) (6).

    Abstract: A method of joining a first pipe section to a second pipe section includes positioning the two pipe sections in an end-to-end configuration to define therebetween a joint to be welded, measuring the degree of alignment of the pipe sections when they are in the end-to-end configuration in a position ready for welding, ascertaining the relative movement required of the pipe sections in order to improve their alignment, effecting the relative movement so ascertained, and welding together the two pipe sections. The method may include the use of geometric data of the end of the pipes in order to ascertain the relative movement required of the pipe sections. A control unit may be used to calculate, using such data, a target orientation that lines up the pipe sections. The measuring step may be performed using, for example, a laser or a camera and backlight.

    Abstract: A misalignment calculation system comprising a misalignment calculator for calculating a misalignment amount occurring in butt welding of end portions of a first steel pipe and a second steel pipe by using profile data measured in a circumferential direction on the end portion of the first steel pipe by presetting a first angle datum, and profile data measured in a circumferential direction on the end portion of the second steel pipe by presetting a second angle datum, wherein the misalignment calculator calculates the misalignment amount in a state in which an angle formed between the first angle datum and the second angle datum is adjusted to an input angle and in which the center of profile data showing an external surface geometry at an end portion of the first steel pipe is aligned with the center of the profile data showing an external surface geometry at an end portion of the second steel pipe so that a misalignment occurring when performing butt welding can be quantified and evaluated.
