Abstract
PURPOSE: To control welding heat input, reduce the hardness of girth weld zones and prevent the induction of cracking, etc. by letting a non-consumable electrode follow the consumable electrode for gas metal arc welding given with weaving in the high speed down welding of the captioned joints.
CONSTITUTION: High-speed down welding is done with a gas metal arc while a consumable electrode 1 as a preceding electrode of the girth joint welding of a pipe 3 is being weaved in order to improve the penetration and bead shape. Welding heat input is added by as much as the heat quantity of the arc by one or more non-consumable electrode 2 as the succeeding arc heat source. The weld beads 5 by the electrode 1 tend to become convex beads. These are made to flat beads 6 by weaving, and the occurrence of the lack of fusion 7 in the groove corners is prevented by the second path. The electrode 2 further slightly melts the upper part of the beads 5 to smooth the surface and the accumulation of layers free from defects is accomplished by the second path and at the same time the cooling rate of the weld zone is decreased.
