The invention relates to an industrial welder intelligent monitoring system; a traditional welder monitoring structure is improved; a staff identity identifying structure is introduced; and on the basis, the invention further relates to a monitoring method of the industrial welder intelligent monitoring system. An internal structure design of a measuring control box (1) introduces a staff identity identifying module to obtain identity information of staff; the identity information of the staff is sent to an upper server (2) for comparing with prestored staff identity information to realize the staff identity verification; according to the verification result, the power supply for a welder is automatically controlled, so that persons without specific welding qualification can be effectively prevented from performing specific welder operations; and based on the staff identity verification, the association between the obtained welder work monitoring data and the staff can be realized, so that the quality event tracking is convenient, and more effective technical support is provided for the welding quality guarantee.
