A WELDING BUG FOR WELDING TOGETHER PIPE SECTIONS WHEN LAYING PIPELINES

摘要

A welding bug (1) is disclosed for welding two pipes (13) together. The welding bug (1) comprises a welding torch (3) for welding in a groove (19) between the pipes. The welding torch (3) is mounted for rotational movement about an axis (21, 23) that is substantially horizontal relative to the welding bug. The torch is moveable during use of the welding bug between an operating position with the welding torch in the groove and a disengaged position with the welding torch (3) is positioned away from the groove. The horizontal axis (21, 23) is parallel to the width of the bug (1) and substantially parallel to the tangent to the pipe cross-section at the location being welded.
