Abstract
Welding methods and apparatus, wherein a welding electrode is oscillated by a motor-driven oscillator in back and forth movements transverse to a weld joint, and an alternating welding current is supplied to the welding electrode in timed relation with the welding tip oscillations so that weld metal is deposited along opposite sides of the weld joint in parallel paths without deposit of weld metal at the center of the weld joint.
