An apparatus and method for use in welding together sections of coiled tubing (6) in the oil industry, wherein the apparatus has a container (14), legs (12) which can be adjusted to adjust the height of the container (14), welding apparatus in the container and slots in the walls of the container. In use the container is raised to the height of the coiled tubing which is to be joined. A winch pulls the ends of the coiled tubing towards a clamp, which holds the two ends of the coiled tubing fixed inside the container, while the ends are welded together. The slots in the walls allow the joined tubing to pass out of the container after the weld is completed. The container provides a controlled environment for welding and weld inspection. |
