Abstract
Based on the comprehensive analysis of welding circuit for MAG (Metal Active-Gas welding) arc power, a system model, through power, cable, wire, droplet and arc, is found, and a voltage function of wire is also developed according to distributed temperature function about a variable of GLW (Genuine Length of Wire). Then, a dynamic and multicycle droplet-voltage mathematic model is also found by the TWC (time-weight coefficient) φ for the equivalent length of transferred droplet and by the transition of wire volume from a solid to a liquid state. Besides these, a arc-voltage function, involved the welding current, the GLW and the height of welding nozzle, is established logically and especially, Meanwhile, the correlative parameters is experimentally analyzed. At last, there made some acute and good dynamic control models of the process parameters of MAG on series of experiments in the paper.
