Abstract

The invention discloses a welding quality monitoring system which comprises a signal acquiring module, a signal conditioning module, a microcontroller and transceiver module and an upper computer. The signal acquiring module is arranged in a welding machine and acquires signals to be detected during welding, the signal conditioning module is connected with the signal acquiring module, the microcontroller and transceiver module are connected with the signal acquiring module, and the upper computer is connected with the microcontroller and transceiver module. The welding quality monitoring system can utilize a signal acquiring circuit and a PIC (positive-impedance converter) single-chip microcomputer to monitor and store intrinsic electric parameter signals in real time during welding, communicate with the upper computer and realize network-based management.

Description

technical field [0001] The invention relates to the technical field of welding control, in particular to a welding quality monitoring system, which has portability and real-time monitoring of the welding process based on the network. Background technique [0002] Arc welding is one of the modern welding methods. It is the most widely used and most important type of welding method. In the total welding production in the world, arc welding generally accounts for more than 60% of the total welding. The electrical parameters in the welding process not only contain information about the performance of the welding power supply, but also include information about the welding quality, such as: core size, shape of the molten pool, depth of penetration, droplet transition frequency and shape, etc. Therefore, real-time electrical signals during the welding process Monitoring is of great significance to ensure the smooth progress of the welding process and the quality of the welded join...
