Zusammenfassung:	PURPOSE:To accurately detect work clearances and to prevent defective welding by presetting guide points for clearance detection on the welding line and repeating a clearance detecting motion upon reaching the respective guide point. CONSTITUTION:Clearance detecting motion repeatedly takes place when the arc welding reaches each of the guide points which have been provided inthe plural number at a fixed interval on the welding line. When a clearance 100 has been detected, welding is performed from the guide point till the next guide point by means of a welding wire 10, taking a weaving motion in the fixed amplitude across the welding line at the right angle. With this welding in a weaving motion the clearance between both arcs 18a and 18b is securely welded.
