In a process for manufacturing welded wire mesh by friction welding the longitudinal wires of said mesh are held stationary at predetermined distances apart and a transverse wire is subjected to tension and caused to oscillate at high frequency and small amplitude in the direction of its own length and is thrust against said longitudinal wires during said oscillation at the crossing points to produce frictional heat in the crossed wires, said oscillation is interrupted upon attainment of welding temperature whereby said crossed wires are welded together, and said thrust is relaxed after cooling and hardening of said welds and the mesh is advanced a step corresponding to the predetermined transverse wire spacing. |
