Abstract
The invention relates to a method and system for establishing a double-pulse MIG welding self-learning expert database. The method comprises the steps of carrying out the fixed-distance calibration ofdouble-pulse MIG welding parameters based on a welding wire and an aluminum alloy base material, and obtaining double-pulse MIG welding fixed-distance calibration parameters; carrying out interpolation in the double-pulse MIG welding fixed-distance calibration parameters through a Taylor interpolation method, and obtaining self-learning double-pulse MIG welding interpolation parameters; and carrying out unified parameter storage on the double-pulse MIG welding fixed-distance calibration parameters and the double-pulse MIG welding interpolation parameters to obtain a double-pulse MIG welding self-learning expert database. According to the method, a method of "fixed distance calibration + Taylor interpolation" is adopted, so that a double-pulse MIG welding expert database is changed into flexible "self-learning" from engraved "read-only"; a Taylor interpolation method is adopted, the difficulty of establishing the double-pulse MIG welding expert database is simplified, meanwhile, unified parameter storage of the double-pulse MIG welding expert database is established, the result precision is improved, and the requirement of engineering practice can be met.
Description
technical field [0001] The invention relates to the field of welding databases, in particular to a method and system for establishing a double-pulse MIG welding self-learning expert database. Background technique [0002] At the 23rd Essen Welding and Cutting Exhibition in 2018, it took a domestic welding company nearly three years to develop a welding expert database for 5-series aluminum alloys. Developed countries such as the United States, Japan, and Western Europe have done a more reasonable job in the research and development of welding expert databases. Instead of relying on a single company, they have gathered the strength of most welding companies in their own welding industry, and have completed a sophisticated and huge database. The database of welding experts avoids the repetition and waste of manpower and material resources, and obtains good results. At present, advanced welding machines equipped with welding expert databases in the United States, Japan, and Eu...
