Abstract:

Abstract: Pulsed DE-MIG welding is a novel welding method which can realize low heat imput. Aimed at the unstable problem of coupling arc in the pulsed DEMIG welding process, a control scheme was proposed which  changed the wire feed speed to adjust the main arc length and  to control the stability of the coupling arc. The simulations and welding experiments of control scheme were conducted based on the Matlab/Simulink and xPC target welding experiment system. The simulations showed that the control scheme was effective, and the welding results proved the simulations and a good weld apperance was acquired.
