Machine has radially adjustable guides for the longitudinal wires. A traveller runs concentric to the pipe axis and carries a supply reel for the encircling wire and a welding head which is radially adjustable. The traveller winds the wire around the longitudinal wires forwarded by a feed device and the head welds the crossing points. The machine has a control for the traveller rotation speed, which is adhered proportionally to the diameter changes of the lattice, so that the circumferential speed of the welding head is const. despite the diameter changes. |
