Regarding g-based filler metals. (Prior art and problems to be solved) Al, -Z low Mg and Al-Mg based aluminum alloys have excellent mechanical properties and weldability, so they are used in railway vehicles and various land-based structures. It is used very widely and in large quantities. However, as the strength of this type of high-strength aluminum alloy increases, stress corrosion cracking becomes more likely to occur. The aforementioned Al
-Zn-Mg and Al-Mg alloys are no exception.
M4. to increase strength. When the Zn content is increased, there is a problem that stress corrosion cracking resistance deteriorates. On the other hand, welded structures are an ideal joining method for lightweight structures and have a long track record of use, but as we move toward higher performance and larger sizes, we need to improve the stress corrosion cracking resistance of welded parts. is always in demand. Furthermore, in recent years, due to the increase in the size of structures and the rationalization of construction, the use of thicker materials has increased, and the stress generated in welds is large, resulting in stress corrosion cracking in welds. The demand for sexual improvement is becoming stronger and stronger. In this regard, 5356 (Al-Mg type) has traditionally been used as a filler metal for high-strength aluminum alloys, but
The actual situation is that the stress corrosion cracking resistance of welded parts is insufficient, and there is a desire for the development of filler metals that can provide welded parts with excellent stress corrosion cracking resistance. The present invention has been made to meet the above requirements, and an object of the present invention is to provide a novel filler metal that can improve the stress corrosion cracking resistance of welded parts of high-strength aluminum 911 alloy. It is something. (Means for Solving the Problem) In order to achieve the above object, the present inventor investigated the cause of the deterioration of the stress corrosion cracking resistance of the welded part in the case of conventional filler metals, and worked diligently to find countermeasures. As a result of repeated research, we discovered a new Al-Zn-Mg filler material and accomplished the present invention. That is, the present invention provides Mg: 3, O ~ 8.0%,
Ti: 0.05-0.3%, Zn: 0.5-3.0%,
B: 0.001-0.2%, Ag: 0.02-1.0
% and Zr: 0.05 to 0.3%, and optionally -C, Ni: 0.03 to 0.3%, Sj: 0.2 to
0.8%, 3Mn: 0.05-0.5% and Cr: 0.05-0.2
AM-Zn-Mg filler metal with excellent stress corrosion cracking resistance, characterized in that it contains one or more of the following % and the remainder consists of Al and impurities. It is. The present invention will be explained in further detail below. (Function) The 〇-Zn-Mg filler metal according to the present invention improves stress corrosion cracking resistance without impairing weldability. Generally, the base metal is treated to prevent stress corrosion cracking through heat treatment during the manufacturing process, but this effect disappears in welded parts, so it is necessary to improve the stress corrosion cracking resistance due to welding. . Stress corrosion cracking is a type of brittle fracture that occurs at grain boundaries.The initial cause of stress corrosion cracking is due to preferential elution of grain boundaries due to potential differences between grain boundaries and within grains. When the amount is increased, the strength increases, but the potential difference between the grain boundaries and inside the grains increases, making stress corrosion cracking more likely to occur. As a result of the inventor's research on measures to prevent this,
When Ag, Ni, and Si, which have high potential, are included in appropriate amounts,
This preferentially precipitates at the grain boundaries of the weld zone and reduces the potential difference between the inside of the grain and the grain boundary, thereby preventing preferential elution of the grain boundaries and improving the stress corrosion cracking resistance of the weld zone. There was found. Next, the reasons for limiting the chemical components in the present invention will be explained. Mg: Mg is the most important element for improving strength, but if the content is less than 3.0%, sufficient strength cannot be obtained, and if the content exceeds 8.0%, the stress resistance Corrosion cracking resistance decreases. Therefore, the Mg amount is set in the range of 3.0 to 8.0%. zn: Like Mg, Zn is an important element for improving strength, but if the content is less than 0.5%, sufficient strength cannot be obtained, and if the content exceeds 3.0%. and stress corrosion cracking resistance and weldability decrease. Therefore, the amount of Zn is set in the range of 0.5 to 3.0%. T1, B: T'', B refines the structure of the weld zone and disperses the stress during solidification shrinkage applied to the grain boundaries, resulting in an effect of improving weld cracking resistance. However, if Tj is less than 0°05% and B is less than 0.001%, there is no effect on improving weld cracking properties, and if Tj: 0.3% and B: 0.2% are contained, macrocompounds are formed. This may occur. Therefore, the amount of Ti is in the range of 0.05 to 0.3%, and the amount of B is in the range of 0.001 to 0.2%. Ag: Ag is an element that significantly improves stress corrosion cracking resistance, but if the content is less than 0.02%, this effect is absent, and if the content exceeds -10%, weldability is poor. Therefore, the amount of Ag is in the range of 0.02 to 1.0%. Zr: Zr is an element necessary for stabilizing the structure, but if the content is less than 0.05%, it will not have this effect, and if the content exceeds 0.3%, there is a possibility that giant compounds will occur. be. Therefore, the amount of Zr is set in the range of 0.05 to 0.3%. Each of the above elements is an essential component, but if necessary, one or more of the following elements may be added in appropriate amounts. N1, Si: Like A and g, Ni and Sj significantly improve stress corrosion cracking resistance, but Ni: less than 0.03% and Sj: 0.
If the content is less than 2%, this effect is not achieved, and if the content exceeds Ni: 0.3% and Sj: 0.8%, weldability deteriorates. Therefore, the amount of Ni is 0.03 to 0.3%, and the amount of Sj is 0.
The range is 2% to 0.8%. Mn, Cr: Like Zr, Mn and Cr are effective in stabilizing the structure, but
Mn: less than 0.05% and Cr: less than 0.05% have no effect, and Mn: 0.5% and Cr: 0.05%
If the content exceeds %, giant compounds may be generated. Therefore, M n fk is 0.05-0.5%, C
The amount of r is in the range of 0.05-0.2%. Note that the filler metal of the present invention is Al-Zn-Mg-based and Al
The present invention can be applied to welding various aluminum alloys, including -Mg alloys, and the welding method and conditions are not particularly limited. Next, examples of the present invention will be shown. (Example) An aluminum alloy having the chemical components shown in Table 1 was melted and cast in a conventional manner to form an extruded rod of 15 mm in diameter, and finally a filler material for MIG of 1.6 mm in diameter. Next, using these filler metals, a typical A
, Q-Zn-Mg alloy 7NO], -T6 material (plate thickness 6 mm) was used to conduct a butt MI (connection test) under the conditions of a current of 280 A and a voltage of 30 V to determine the mechanical properties of the welded joint. Weldability and cutting stress corrosion cracking resistance of the welded part were investigated. The results are shown in Table 2. Weldability was measured using a 6 mm thick slit type weld cracking test piece in the slit type cracking test. The cracking rate was determined and evaluated using the following formula: cracking rate (%) = (crack length/total weld length) x 100. The stress corrosion cracking resistance of the weld was tested according to the procedure shown in Fig. A piece (plate material 1. weld bead 2) is supported at three points by support metal fittings 3 having pins 5, and a stress of 15 kg/llm2 is applied to it, and 3 g/]-NaCQ36 g/IC at 100°C.
ry3-30g/] was immersed in a 2Cr207 mixed aqueous solution, and cracks were observed and evaluated. From Table 2, it can be seen that the filler metals of the present invention examples are all 53% of the conventional filler metal.
It can be seen that the stress corrosion cracking resistance is significantly superior to that of No. 56 filler metal, and the strength and weldability of the welded joint are also good. In addition, the comparative example is inferior in any of the strength, weldability, and stress corrosion cracking resistance of the welded joint.
