Abstract

PURPOSE: To contrive the improvement of penetration at both ends of the weld metal and the lapped portion, by splitting the hoop into the band type electrodes of specified shape using the cutter, and by employing an apparatus for making different the current density of each band type electrode according to the specified method, in the band arc welding.
CONSTITUTION: The wide hoop 1 is supplied and is splitted into at least two or more bands in the longitudinal direction by the cutter 4 constituted of the edge 2a of the feed roller 2 and the groove 3a fitting to above edge 2a of the press roller 3; hereby, the band type electrodes 1a, 1b, 1c, being connected at suitable intervals are obtained. The power supply portions 6a, 6c, of the electrode slips 1a, 1c, on both ends are set at the position nearer to the parent metal 8 of similar material than the power supply portion 6b of the electrode slip 1b, and the power is supplied from the power source 10 to above three electrode slips and the parent metal 8, and the arc welding is executed. The electric resistance across the power supply portions 6a, 6c, and the parent metal 8 becomes smaller than that of the power supply portion 6b, so that more heat is inputted to both ends of the weld zone and the condition of good penetration is formed. Besides, for the lapped portion, the position of the power supply slip is selected according to the similar idea.
