ABSTRACT:
A method and apparatus for automatically forming and welding wire mesh cages useful in reinforcing standard concrete pipe. Prefabricated wire mesh is fed from a coil through a straightener and shear section onto a mandrel. A predetermined length of the wire mesh is sheared and then rolled in cage form on the mandrel and, once rolled, is welded to retain the mandrel shape. The entire operation is automatically controlled by an integrated electrical control and logic system and is run by a single operator. The welding system employs a plurality of small TIG welders which are operated in sequence to reduce power supply demands and which can weld wire in any condition even rusted wire.
