On the Lay Down Welding Process (Fire-Cracker Welding), using the conventional A.C. Welde, we carried out a systematic research on the direction of the arc blow, making the following 7 factors as changeable factors : kind of the covering, the covering composition, the eccentricity ratio of electrode, arc current, the groove angle of base metal welding position, and the gap between electrode and base metal. The characteristic phenomena are summerized as follows; (1) The arc blow of length direction decrease by following (a)-(g), respectively. (a) Changing the coverings from acidic type to basic type. (b) Increasing iron powder in the coverings and decreasing gas materials. (c) Increasing the eccentricity ratio of electrode. (d) Decreasing the arc current. (e) Decreasing the groove angle of base metal. (f) Changing the welding position from horizontal to flat. (g) Decreasing the gap between electrode and base metal. (2) The arc blow of side direction decreases by following (a)-(f), respectively. (a) Changing the coverings from acidic type to basic type. (b) Increasing the eccentricity ratio of electrode. (c) Increasing the arc current (d) Increasing the groove angle of base metal. (e) Changing the welding position from horizontal to flat. (f) Decreasing the gapbetween electrode and base metal. Above-mentioned arc blows are clearly explained due to geometrical arrangement of welding parts and characteristic of electrode, mentioned above.
