Abstract

PURPOSE: To control the cooling speed of the 1st beads and improve product accuracy by performing arc welding for the joint part then forming the 2nd beads under predetermined conditions.
CONSTITUTION: Other carbon steel 2 is used as the base material to be welded to a carbon steel material 1 and known arc welding is performed to their joint part 3, whereby weld beads 4 are formed. Next, beads 5 are formed in combination in the position away by a preset distance l from the center of the weld beads 5. As the conditions for this case, the beads 5 are selected at such a position and length and shape of melt frozen part at which the cooling rate of the weld zone of the weld beads 4 become less than the critical cooling rate relating to the occurrence of hardness and the thickness of the beads 5 and the projecting amount, etc. from the base material 1 to be welded are so selected that the mean stress by the load acting upon the weld zone of the 1st step beads 4 during use becomes less than the preset rate. Hence, over-strength by the beads 5 and the cooling rate is controlled by the same as well, thus slow cooling takes place and hardness is lowered.
