Digital Monitoring and Control System Based on Ethernet for Twin-Arc High Speed Submerged Arc Welding

The Ethernet communications was applied to dynamic monitoring and control of high-speed twin-arc submerged arc welding process, with its characteristics of high transmission speed, large capacity and reliability, a digital monitoring and control system based on Ethernet was designed. The sequential control of twin arc-starting and -ending was achieved, and the formation of weld seam was improved with the guarantee of stability and order of welding process, which achieved the technology of twin-arc high speed arc welding.
