摘要：The ethernet technology is used in multi-arc submerged arc welding systems communicate with each other. The structure of twin-arc high-speed SAW (Submerged arc welding) equipments based on Ethernet is proposed. The welding equipment technical requirement for Ethernet is discussed. The crucial implementations of Ethernet TCP / IP in the welding equipment is presented including designs of ARM (Advanced RISC Machines)-based intelligent control unit, communication program, synergistic controlling procedures and monitoring program of welding process. The results of experiment show that the synergistic controlling for welding process, arc-starting and arc-ending are achieved with the characteristics of high transmission speed, large capacity and reliability. The formation of weld seam is improved with arc stability, and the technology of twin-arc high speed arc welding is achieved.
