Beschreibung
Zusammenfassung:	A submerged-arc welding machine comprises a welding head pivoted to a frame of the machine so as to be rockable across the seam of a workpiece being welded, and a vertically movable oscillation mechanism provided with an eccentric cam engaging the welding head for causing the welding head to rock across the seam as the cam rotates. Further included is an oscillation amplitude adjusting device for moving the oscillation mechanism as well as the cam vertically, whereby the axis of rotation of the cam is adjustable relative to that point on the frame about which the welding head pivots to adjust the amplitude of the rockable movement of the welding head.
