A pipe welding method for thin-walled pipes 20, 21 includes mounting a support sleeve 1 having a resilient unitary C-shaped body 2 across abutting ends 23, 24 of the thin-walled pipes 20, 21. Free ends 4, 5 of the body 2 are pulled together to clamp the sleeve 1 about the pipes 20, 21 bringing the pipes 20, 21 into alignment. The pipe ends 23, 24 are then tack welded together through welding access openings 6 in the body 2. After removal of the sleeve 1 the pipe ends 23, 24 are fully welded together. |
