The invention discloses a thin-wall corrugated pipe welding method and welding clamp. The welding method includes the steps that a special-shaped pipe is fixed to a base of the clamp; a welding layer of a corrugated pipe and the special-shaped pipe are tightly clamped through a hoop; the corrugated pipe and the special-shaped pipe are subject to repairing and matching treatment; and the corrugated pipe and the special-shaped pipe are welded. By means action force of the hoop, the shape of the corrugated pipe can be effectively guaranteed, and the deformation amount of the corrugated pipe is further reduced; the corrugated pipe and the special-shaped pipe are subject to repairing and matching treatment, and therefore the butt joint effect of the corrugated pipe and the special-shaped pipe can be guaranteed, and the corrugated pipe and the special-shaped pipe can be better matched in size, the welding efficiency is improved, and the condition of repair welding caused by the size matching process and the like ar
