Abstract

In this article, curve fitting is conducted on the original data of aluminum alloy via matlab. Then, to find out a fitting curve with optimal effect, comprehensive analysis is made on the judgement quantitative index of curve fitting. The wire feed rate of other given current is obtained with such fitting curve so as to complete unified expert database. At last, aluminium alloy welding test is conducted in the multifunctional and digital welding machine developed by the laboratory. The test result shows that the expert database generated by 8-order fitting curve can meet the requirement of wire feed rate under the condition of random given current and within the scope of welding current. The unified regulating function is realized as a result.
