Expert Database of Unified Parameter Adjustment Based on Long-step Calibration and Cubic Spline Interpolation

Abstract

There are many kinds of aluminum alloys suitable for double-pulse MIG welding, however, the welding parameters are much more and they cannot be easily adjusted. Thus, it is necessary to establish the expert database for the welding source. In order to improve the adjustment performance to precisely control the welding current, this paper proposes a kind of expert database of unified parameter adjustment based on the long-step calibration and cubic spline interpolation to make the welding parameters “continuously adjusted” and “precisely matched” as well as make the test results verified.
