Abstract

The invention relates to a multi-sensor feedback wire feed method. In the method, a sensor and a control system are additionally arranged on the basis of an original and classical wire feeder so as to provide a scheme for adjusting the electric arc height, and the like through acquiring, transmitting, analyzing and adjusting real-time data transmitted by a welding wire. The method can be suitable for various welding environments, and particularly, the adaptability to a specific environment which cannot be reached by manual work to adjust a welding wire feed system is greatly enhanced. The real-time monitoring and timely adjustment ensure that the utilization rate of the welding wire is greatly improved, and the welding quality is indirectly improved.

Description

technical field [0001] The invention relates to a welding wire feeding method, in particular to a wire feeding method with multi-sensor feedback, convenient use, real-time monitoring and automatic control of welding wire feeding speed. Background technique [0002] With the increasing influence of welding technology in today's industrial production, especially in my country's automobile and even aerospace enterprises, the requirements for welding efficiency and welding quality are getting higher and higher, and the automation of welding equipment is also imminent. In welding equipment, it is extremely important to have a wire feeding mechanism with excellent performance. The stability of wire feeding, the accuracy of wire feeding and the cooperation between wire feeding and welding arc greatly affect the performance of the weld. In melting electrode arc welding , Unstable wire feeding will cause fluctuations in welding parameters, arc state, and high frequency of defects dur...
