ときの形状を測定したものである。As a result of investigating the cause of such a wire trajectory abnormality at the tip of the tip, the inventors of the present application have found that the waviness of the wire interferes with the curved portion of the wire feeding system. . As shown in FIG. 2, the wire is fed with a swell having a pitch and an amplitude. Therefore,
The wire tensile strength 570 to which the inventors of the present application can actually manufacture
When the pitch and the amplitude were changed in the range of 860 N / mm 2 and the occurrence of wire traces and welding defects was confirmed, it was found that the ones in which abnormalities were less likely to occur had a pitch of 1000 to 2700 m.
m, and the amplitude was 100 to 700 mm. As the length of the wire feed path from the wire load to the non-consumable nozzle electroslab welder increases, the feed load increases, resulting in a pitch of 1200 to 2500 mm and an amplitude of 150.
~ 600 mm is desirable. The pitch and the amplitude are obtained by measuring the shape of five wires taken out from the storage pack so as not to have a habit, and deployed on a plane so as to release the elastic deformation of the wires.

イヤ径とは公称径を示す。Further, during welding, wire feeding resistance is generated in the current-carrying tip portion due to micro fusion, but if the wire trace at the tip of the tip becomes abnormal, the wire behaves irregularly in the straight portion directly above the tip, It has been found that when the straight line portion is less than 600 mm, the trajectory irregularity leading to welding defects is promoted. However, in the non-consumable nozzle type electroslag welding, this straight line portion is always present as a nozzle up to about 1500 mm.
The experiment was carried out on the basis of 00 mm, but it was confirmed that the nozzle length covered up to 1700 mm within the range of the present invention. The wire diameter is 1.4 mm
If it is less than the above value, a sufficient current for melting the inside of the groove cannot be flowed, resulting in defective fusion. Further, if it exceeds 2.4 mm, the rigidity of the wire is increased, the feeding load is increased, and the current cannot be sufficiently increased with the commercially available welding current, so that insufficient penetration easily occurs. In addition, in this invention, a wire diameter shows a nominal diameter.

抵抗が大きくなってしまう。Further, regarding the above wire feeding abnormality, the following items are also important factors. 1. Cu plating amount It is appropriate that the Cu plating amount is 0.12 to 0.55% by weight, and in this range, the feeding resistance due to the minute fusion is small and the trajectory abnormality is unlikely to occur. Even if the trajectory abnormality occurs, the degree is small. Cu plating amount is 0.55
When the content is more than the weight%, there are disadvantages that the plating cost becomes high, the nozzle is clogged due to the peeling of the plating, and the crack resistance of the weld metal is lowered. Also, Cu
When the plating amount is less than 0.12% by weight, the feeding resistance due to the minute fusion becomes large, and the wire trace abnormality at the tip of the chip is likely to occur, and the degree thereof becomes large. Desirably, the Cu plating amount is in the range of 0.18 to 0.35% by weight. 2. Wire Tensile Strength The wire tensile strength is suitably 570 to 860 N / mm 2 . If it exceeds 860 N / mm 2 , friction and deformation resistance in the wire feeding path are large, stable feeding cannot be performed, and welding becomes unstable. Wire tensile strength is 570
If it is less than N / mm 2 , abnormal wire traces at the tip of the chip are likely to occur, and the extent thereof is large. Desirably, the wire tensile strength is in the range of 600-840 N / mm 2 . 3. Current-carrying chip The current-carrying chip is a replaceable one, and the length of the current-carrying part is 25 to 60 mm. When the length of the current-carrying portion is longer than 60 mm, when the main current-carrying point moves to the upper part of the chip, the wire is heated in the chip and the wire is fused to the chip. If the length of the current-carrying portion is less than 25 mm, the current-carrying is not stable and micro fusion tends to occur, resulting in an increase in feeding resistance.
