Abstract: The electrical parameters of the short circ it transfer process in CO arc welding were meas red by means of welding q ality analyzer
2
of Hannover. The reg lar of the arc- time and short- circ iting transfer cycle time was investigated nder the high speed welding . The infl -
ence of the short- circ it transfer parameters on the welding process stability in high speed CO welding were analyzed. Thro gh research of
2
c rrent and voltage waveforms in short- circ it period and arc period, the res lts show that the c rrent waveform control is an effective method
to improve stability of welding process.
