A method of consumable electrode arc welding with the end of the electrode submerged into the molten pool wherein the maximum cross sectional dimension of the electrode end to be submerged into the molten pool is chosen so that it does not exceed twice the minimum dimension of this cross-section. Said dimensions are made to fit the required width of the weld by adopting the minimum dimension of said cross-section of less than the width but no less than half the width, for the same weld width required. The arc length is set below said minimum dimension, and the consumable electrode is fed at a speed lower than the welding speed, choosing the ratio of the consumable electrode feed speed to the welding speed, for the same weld width required, so that the greater the cross-sectional area of said end of the consumable electrode, the smaller is the ratio. |
