Description
【発明の詳細な説明】 本発明は、裏波ＴＩＧ溶接溶加材の改良に関する。[Detailed description of the invention] The present invention relates to improvements in Uranami TIG welding filler metals.
周知の如く、合金鋼板の片側溶接時にＴＩＧ（タングス
テン電極イナートガス）溶接によって裏波溶接を施工す

イナートガスを流通させ、かつ開先の表側を裸ワイヤ溶
加材を使用して開先底部の裏側に良質なビードを形成す
ることにより行われていた。As is well known, when welding an alloy steel plate on one side using TIG (tungsten electrode inert gas) welding, a grooved jig is placed on the back side of the groove of the welding material to allow inert gas to flow through the groove. This was done by using bare wire filler material on the front side of the tip to form a high quality bead on the back side of the bottom of the groove.
しかしながら、こうした裏波溶接によれば、溝型治具の
着脱が面倒であるとともに、溝型冶具内に流通させるイ
ナートガスの消費量が多くなるという欠点を有する。However, such Uranami welding has disadvantages in that it is troublesome to attach and detach the grooved jig, and the amount of inert gas flowing through the grooved jig increases.
本発明は、上記事情に鑑みてなされたもので、溝型冶具
の着脱が簡単でしかもイナートガスの消費量を従来と比
べて軽減できる裏波ＴＩＧ溶接溶加材を提供することを
目的とするものである。The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a Uranami TIG welding filler material that allows easy attachment and detachment of a grooved jig and reduces inert gas consumption compared to conventional ones. It is.
以下、本発明の一実施例を第１図を参照して説明する。An embodiment of the present invention will be described below with reference to FIG.
図中の１は、例えば厚さ０．１ｍ、直径４ｍの筒状の金

不鋳鋼５ＵＳ３０８Ｌである。この外皮１の内側には、

皮１の内側に均一に充填することが困難である。1 in the figure is a cylindrical metal outer skin having a thickness of 0.1 m and a diameter of 4 m, for example. The material of this outer skin 1 is, for example, uncast steel 5US308L. Inside this outer skin 1,
It is filled with 7 luxes 2 whose weight is approximately 115 times the weight of the shell 1. However, the weight of this flux 2 is
It is preferable to set it as 1/8 - 3/2 of the weight of. Here, if the weight ratio is smaller than 1/8, it is difficult to uniformly fill the inside of the outer skin 1 with the flux 2.

% or less of metal fluoride. Here, the weight ratio is 30
%, it causes fluoride pollution. Furthermore, as a flux component, slag forming material is added in an amount of 2 to
Contain 6%. Here, if the slag forming material is less than 2%, the flux 2 cannot be uniformly filled into the outer skin 1. On the other hand, if it exceeds 6%, welding workability is likely to be impaired. Note that the components of the slag forming material are as shown in the following table, for example.

Set b. Subsequently, while supplying the filler metal 4 according to the present invention to the groove bottom 5 of the steel plate 3a13b, the TI
The filler metal 4 and the groove bottoms 5 of the steel plates 3a and 3b are heated by the tungsten electrode 6 of G welding. As a result, the flux 2 in the filler metal 3 melts and flows from the front side of the groove bottom 5 to the gap between the steel plates 3a and 3b, and then flows to the back side. After cleaning, it adheres to the back side and forms a film. Further, the surfaces of the steel plates 3a and 3b of the groove bottom 5 and the outer skin 1 of the filler metal 3 melt and flow in the inert gas to form a weld metal (bead) of deposited steel at the groove bottom 5. In this case, the bead is formed with its upper surface covered with inert gas and its lower surface covered with molten flux, completely shielded from the atmosphere, so that it has a beautiful surface with no internal defects.

浄化してビードに欠陥を生じることはない。According to the filler metal of the present invention, a predetermined amount of flux 2 is filled inside the outer skin 1, and this flux 2 contains 30% or less of metal fluoride by weight, and also contains a slag forming material. Since the entire product has a structure in which the content is 2 to 6% by weight, when welding the steel plates 3a and 3,
The groove-shaped jig for inert gas can be easily attached and detached from the back side of the groove b, and the consumption of inert gas can be reduced compared to the conventional method. Furthermore, the surfaces of the welded parts of the steel plates 3a and 3b are cleaned without causing defects in the beads.
