<p>A welding bug (1) comprising a welding torch (3) for welding in a groove (19). The welding torch (3) is mounted for rotational movement about an axis (21) that is substantially horizontal, relative to the welding bug, (typically tangential to a pipe during use) so that the torch is moveable, during use of the welding bug (1) when arranged to enable the torch to weld in a groove, between (i) an operating position, and (ii) a disengaged position in which the welding torch is positioned away from the groove (19). The welding bug may be less cumbersome and more compact than some known arrangements.</p> |
