The invention discloses an electric welding machine cluster monitoring control method based on IPv6. The electric welding machine cluster monitoring control method comprises the steps that 1, electricwelding machine IPv6 network nodes are subjected to networking configuration, a wireless communication protocol of 6LoWPAN is configured on welding data collecting nodes, an IPv6 address is set, andcollecting node networking of a welding production site is carried out through the automatic configuration of PIv6 and the self-networking characteristics; 2, welding production parameters are collected, data is collected through a current-voltage data collecting sensor on an electric welding machine, current and voltage are collected, and the data is transmitted to a data processing center; 3, the data format is converted to a data structure form commonly used in the welding field; 4, the welding data is analyzed; 5, the welding data is stored, and cloud platform data operation is carried out; and 6, certain measures are taken according to whether the current and voltage exceed a safety threshold value. According to the electric welding machine cluster monitoring control method based on IPv6, IPv6 networking of welding monitoring equipment is achieved, the size of the welding monitoring equipment is reduced, the work space is not occupied, and the electric welding machine cluster monitoring control method is suitable for large-scale mass production.
