Abstract

PURPOSE: To repair the start and end tip part of weld bead good in a short time, by fusing and smoothing the start tip part of root pass bead by nonconsumable type electrode arc and forming Uranami bead and then, conditioning the bead on and after the second layer in the same way.
CONSTITUTION: The electrode 10 is started in a low arc electric current and low moving velocity from the front point 11 of the start tip part 6 of root pass bead and repairing part is preheated. Next, the electrode is moved in a high arc current and high moving velocity and the Uranami bead 12 is formed fusing the groove root part and then, flat bead is formed pouring molten metal of the part 6 in produced concave part. Then, moving velocity of the electrode 10 is decreased in the same arc current and the Uranami bead 13 is formed by penetrating the root pass bead 4 and fusing the rool part and the form of the bead 4 is conditioned. Molten pool is kept small by decreasing the arc current and slowing down the moving velocity moreover and the unevenness 15 of boundary between the bead and unrepaired part by flattening the repair band 14. Bead end is processed in the same way. Welding defect is removed by carrying out bead conditioning on and after the second layer in the same way.
