Abstract
Improved methods and apparatus for welding, wherein during welding the welding electrode is oscillated laterally of the weld path, and the welding current pulse frequency and oscillation frequency are correlated whereby weld metal droplets are deposited when the electrode is at its limit of movement away from center at each side of the weld path. During each cycle of oscillation of the welding electrode, a controlled number of weld metal droplets is deposited at each side of the weld path. An electrical circuit controls the electrode oscillation frequency and the welding current pulse frequency to be in correlation, and controls the number of weld metal droplets deposited at the opposite sides of the weld during each oscillation of the welding electrode.
