に関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a composite wire for gas-shielded arc welding that uses a relatively thin plate and is used for welding rust-proof steel structures. This invention relates to a composite wire for high-speed gas-shielded arc fillet welding that produces high-quality weld metal with fewer weld defects such as bits and blowholes during fillet welding.

る。(Prior art) In recent years, composite wires for gas-shielded arc welding (hereinafter referred to as composite wires) have been widely used for welding steel structures using various types #1, including mild steel and 50 kg class high tensile strength steel. ing. The reason for this is that composite wires have good welding workability and a good bead appearance and shape due to the effects of the flux filled inside them, as well as fast wire welding speeds and improved welding efficiency. .
しかし、最近の溶接の自動化・ロボット化の動向下にお
いて、更に高性能・高能率な複合ワイヤの開発が待望さ

。This composite wire has an outer skin made of steel and an inner part of 10 to 3
Although it is constructed by filling 0% flux, its structure has various cross-sectional shapes as shown in FIG. The flux to be filled inside can be roughly divided into (1) slag agents such as titania type, and 84. (2) wires made of a dispersing agent/alloying agent such as Kn; and (2) wires made of iron powder + metal powder such as S L 1Mn. The present invention relates to the latter metal powder composite wire.

（２）スラグの生成が少ない。(2) Less slag generation.

用化ができていないのが現状である。Although metal powder-based composite wires have excellent characteristics, especially during arc welding using carbon dioxide as a shielding gas, spatter generation is more noticeable compared to titania-based composite wires, and Fillet welding often produces pits and blowholes in the bead, making it difficult to put it into practical use at present.

必ずしも満足できるものではない。As means for solving such problems, techniques described in, for example, Japanese Patent Application Laid-open No. 82-248593 and Japanese Patent Application Laid-open No. 84-31596 are known. The former is a technique that attempts to solve the above-mentioned problems by specifying the chemical composition relative to the total weight of the flux-cored wire, and the latter is a technique that attempts to solve the above-mentioned problems by specifying the amount of carbon and oxygen, but these techniques are not necessarily satisfactory in high-speed welding.

The present invention provides a metal powder-based composite wire that can be welded.

Therefore, 90% or more of the flux must be metal powder. Note that the metal powders mentioned here include iron powder as well as C1Si, Mn, Ti,

ことを見い出した。By adjusting the amount of metal powder added within the above range, it is possible to improve welding efficiency, which is a characteristic of metal powder-based composite wires, but it is necessary to reduce pits and blowholes, which were the biggest problems in the past. I can't. Therefore, as a result of repeated experiments aimed at reducing pits and blowholes, the inventors found that the C
It has been found that JI greatly contributes to the occurrence of pits and blowholes.

Metal powder wires filled with C of 5% and having the C content of the wire as a whole varied in the range of 0.10 to 1.70% as shown in Table 2 were prepared and subjected to welding. The wire has a diameter of 1.2

) are stacked as shown in Figure 3, and the stacked parts are horizontally stacked and fillet welded. The blowhole occurrence rate in Figure 1 is determined by performing a radiographic test on each bead, measuring the blowhole width in the bead length direction from the film, and expressing the total blowhole width relative to the bead length as a percentage. This is what I did.

ローホールの発生を抑制しているものと考えられる。From this figure, it can be seen that the amount of pits and blowholes generated is extremely small in the region where the amount of C in the wire is 0.50% or more. The reason why there are fewer pits and blowholes in this area is not clear, but it is speculated as follows. That is, when the C content is high in a metal powder wire, it is thought that an intense CO reaction occurs in the droplets during welding, and this reaction is thought to suppress the generation of pits and blowholes.

％超ではすみ内部が過度に硬化し耐割れ性が危惧される
ことから、本発明ワイヤのＣ量は０．５０〜１．５０％
とした。Since the droplet detached from the tip of the wire has a high C content, the partial pressure of CO or CO2 on the droplet surface increases due to the oxygen in the arc atmosphere, and this partial pressure causes the Zn plated on the steel plate to vaporize due to the arc heat. It is thought that the Zn vapor partial pressure becomes higher than that of Zn, making it difficult for Zn to penetrate into the droplets, thereby suppressing the generation of pits and blowholes. In this experiment, even if the Cil in the wire exceeds 1.50%, it is effective in suppressing pits and blowholes;
If the carbon content exceeds 0.5%, the inside of the corner will become excessively hardened and the cracking resistance will be compromised.
And so.

Therefore, the amount of added Sl and Mn may be smaller than usual, and the amount of Si in the wire should be 0.70% or less, and the amount of Mn should be 0.

Any method is applicable, but in consideration of automation and robotization, the seamless wire shown in FIG. 2(D) is preferable. Further, in the case of welding using the wire of the present invention, the composition of the shielding gas used may be a mixture of oxygen gas or argon gas in addition to carbon dioxide gas. In the case of a gas mixture with argon gas, the arc stabilizing effect is superimposed, making it possible to weld with less spatter.
