Abstract
According to the thick plate welding quality monitoring and control system and the welding method of the thick plate welding quality monitoring and control system, high-quality welding of a thick plate is achieved through quality monitoring and control over the welding process. The system comprises a welding subsystem, a welding quality monitoring subsystem and a computer control subsystem, the welding quality monitoring subsystem monitors the welding process in real time; the computer control subsystem comprises a feature analysis module, a welding quality control module and a welding process expert system module; the feature analysis module extracts a molten pool feature value and a welding electric signal feature value and judges the type of a welding defect; a welding process database and a relational database between welding process parameters and welding defect rates are stored in the welding process expert system module; before welding, the welding process expert system module plans a welding path and welding process parameters of each welding seam; the welding quality control module controls the welding subsystem to conduct welding and conducts rating judgment on welding seams, and whether welding needs to be stopped or welding process parameters need to be adjusted or not is determined.
Description
technical field [0001] The invention relates to the technical field of intelligent welding, in particular to a thick plate welding quality monitoring and control system and a welding method thereof. Background technique [0002] Thick plate welding is widely used in power generation equipment, petrochemical and rail transportation. Under normal circumstances, multi-layer and multi-pass welding is required for thick plate structures, and the welding quality is affected by many factors. The complexity and instability of the welding process will lead to defects, and the market has proposed the accuracy and speed of welded components. In order to meet higher requirements, most of the current thick plate welding processes are manual welding or robot welding after the completion of radiographic inspection to test the quality of the weld, and the welding layer that does not meet the welding quality requirements is polished and removed for re-welding. The monitoring of quality chan...
