Abstract

In pipe welding apparatus (1) for welding pipe sections together to form a pipeline,upper and lower pipe sections (2, 3) are abutted, end-to-end, and welded together by two or more welding heads (5) that travel around a circumferential guide (4) extending around one of the pipe sections (2). Welding supplies, such as electric power, cooling water and shielding gas are supplied from supply equipment (9, 10, 11) through a distribution manifold (18). The supply equipment (9, 10, 11) thus distributes welding supplies to each of the welding heads.
