Abstract

The invention provides a device and method for wirelessly detecting welding parameters, and relates to the technical field of welding. According to the device and the method, the method comprises thesteps of: collecting current and voltage signals during welding work through a current sensor and a voltage current; removing industrial interference waves from the collected electric signals by a signal conditioning circuit, performing A/D conversion through a single-chip microcomputer to convert analog signals into digital signals; transmitting the converted digital signals to an upper computerthrough a wireless transmission module; and storing and displaying information such as a data oscillogram and the like on the upper computer. The upper computer stores a welding parameter range, whenthe detected data is not the same as a given parameter range, the upper computer achieves feedback functions such as automatic prompting and alarm. The wireless communication technology is applied tothe welding detection process, so that the problems that the environment of a welding workshop is complex, a wired detection method is troublesome in wiring, poor in expansibility, high in cost, difficult to check line faults and the like are effectively solved, errors can be found in time conveniently, adjustment is conducted in time, and the welding quality is improved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a device and method for wirelessly detecting welding parameters. Background technique [0002] In the welding process, the welding process parameters directly affect the quality of the welding quality, so the correctness of the welding process parameters must be ensured during the welding process. For different welding equipment, welding methods and welded workpieces, it is necessary to ensure that the welding process parameters are within its specific range, which requires real-time detection of welding parameters in order to control the welding quality. Therefore, real-time monitoring and detection of working parameters in welding work is an important guarantee for improving welding quality. [0003] At present, the traditional method of testing welding quality is usually offline testing, that is, testing the quality of weldments after the welding work is completed, but this ...
