Abstract

PURPOSE: To make the arc stable, shift globules smoothly and obtain the weld zone of high quality by limiting the current change width between peak current and base current and pulse current time.
CONSTITUTION: The current change width IP-IB between peak current IP and base current IB is adjusted to ≥300A, and the time TP from the start of rise of the pulse current IP till the start of fall thereof is kept within a 0.2ms≤4ms range. Further, when the time of the base current IB is short in a spray region, and arc sound is produced within the prescribed current change width, the value of the base current IB is increased, average current value Im is increased and base current time TB is made long. To shift one globule surely with one time of pulse, the peak current IP and the peak current time TP are so set as to attain IPK.TP=C. At this time, C is the constant determined by the diameter and material of a wire, and K is 1.9W 2.5. Further it is possible to make the adjustment of welding current much easier by associating wire feed speed and the base current time.
