Abstract
Apparatus for making a circular weld using the submerged-arc welding process, the apparatus comprising a generally horizontal, extendible and contractible boom having inner and outer ends, the boom being supported adjacent the inner end for rotation about a vertical axis, a mounting member mounted on the outer end of the boom for vertical movement relative thereto, a swing arm mounted on the mounting member for pivotal movement relative thereto about generally vertical axis, a support member mounted on the swing arm for pivotal movement relative thereto about a generally horizontal axis, a welding torch fixed to the support member for movement therewith, a spool supported by the boom for rotation relative thereto about a generally horizontal spool axis, and an electrode wire wound around the spool and extending between the spool and the torch.
