PURPOSE: A method for manufacturing a welded wire net for a water pipe is provided to improve productivity and reduce failure rate by naturally forming bent parts of longitudinal wires of a socket unit. CONSTITUTION: A method for manufacturing a welded wire net for a water pipe is as follows. Longitudinal wires(6,9) for body units and socket units of a welded wire net are continuously supplied with a height difference(H) between the upper longitudinal wires for the body units and the lower longitudinal wires for the socket units. Transverse wires(7,7b) are arranged on the longitudinal wires at the right angles, wherein the arrangement area of the transverse wires are divided into first through third areas. In the first area, the crossing parts of the transverse and longitudinal wires are spot welded and the free ends of the transverse wires, which protrude from the longitudinal wires for the body units, are bent to be spot welded to the longitudinal wires for the socket units. In the second area, the crossing parts of the transverse and longitudinal wires are spot welded, the free ends of the transverse wires, which protrude from the longitudinal wires for the body units, are bent to contact to the longitudinal wires for the socket units, and the longitudinal wires for the socket units are pressed down to secure extra length.
