Compare with the method for prior art, Si measures increase, by weight percentage, improves 5.351.2%.Because the increase of Si amount, the skewness of Si reduces, and the weld crack in weld metal/parent material interface reduces.In addition, do not produce any defective at weld part yet.(embodiment 2)
In order more to suppress the dilution rate of mother metal than embodiment 1, form step bevel for welding 16,17 shown in Figure 3 and triangle bevel for welding shown in Figure 4 18,19, and the weldering that matches of step shape fill out alloy 20 and and the weldering that matches of triangle fill out alloy 21 and insert between the bevel for welding 16,17 respectively and between the bevel for welding 18,19, make on one side electron beam 12 runouts, on one side fusion weld fill out alloy 20 and weldering and fill out alloy 21 and weld.
Compare with the embodiment 1 that adopts the ring-type weldering to fill out alloy 11, adopt the weldering that matches with step-like bevel for welding 16,17 to fill out the welding that alloy 21 is filled out in weldering that alloy 20 and employing and triangular shape bevel for welding 18,19 match, the dilution rate of mother metal reduces more, the Si amount more increases, and Si is more evenly distributed.
In addition, for fill out the little welding of difficult weld metal 10 in the alloy 11 in the ring-type weldering, also can guarantee the fully Si of amount.(embodiment 3)
In order to suppress the dilution rate of mother metal, the method for two ora terminalis that join with bevel for welding that the present inventor has worked out that the welding weldering fills out alloy.Expression shines weldering with electron beam 12 and fills out the weld part that obtains on two ora terminalis of alloy 11 among Fig. 5.On conductor tube 6 and terminal part 7, be pre-formed with the ring-type weldering and fill out the linearity bevel for welding 8,9 that alloy 11 matches.Electron beam 12 is filled out alloy ground near weldering earlier beam centre is shone the ora terminalis that alloy 11 is filled out in the weldering of joining with bevel for welding 8, suppresses the fusion of mother metal (conductor tube 6).Then, electron beam 12 is filled out alloy ground near weldering intrafascicular understanding without being told is penetrated the ora terminalis that alloy 11 is filled out in the weldering of joining with bevel for welding 9, suppresses the fusion of mother metal (terminal part 7).
In this method, the dilution rate of mother metal also reduces.As a result, the Si amount in the weld metal 10 increases, and the distribution of Si improves, and reduces weld crack.(embodiment 4)
Adopt the device of embodiment 1, the weldering that Al-Mg class alloy is constituted is filled out between the bevel for welding 9 that alloy 11 inserts the bevel for welding 8 of conductor tube 6 and terminal part 7, Yi Bian make the electron beam runout, Yi Bian fusion weld is filled out alloy 11, welds.Mg amount in the weld metal 10 is adjusted to 0.87 to 5.0% by weight percentage.
In addition, the weldering that is made of Al-Mg-Si class alloy is filled out between the bevel for welding 9 that alloy 11 inserts the bevel for welding 8 of conductor tube 6 and terminal part 7,,, weld Yi Bian fusion weld is filled out alloy 11 Yi Bian make electron beam 12 runouts.Mg amount in the weld metal 10 all is adjusted to 0.87 to 2.0% in percentage, and the Si amount is adjusted to 1.2 to 4.8%.
The independent interpolation of Mg and the interpolation of Mg and Si can make Mg amount and Mg amount and the increase of Si amount in the weld metal 10, can effectively prevent weld crack.(embodiment 5)
In addition, also done adding the research that material carries out the research of all changes and changes the high energy beam irradiation position.Also studied on preformed bevel for welding and formed the method that alloy is filled out in weldering with built-up welding or plasma spraying.Fig. 6 represents to fill out one of alloy example with the weldering that the atmospheric plasma plasma spraying forms.Produce electric arc 23 from welding gun 22, heat the powder 24 of filling out alloy as weldering, form the weldering filled gold with meltallizing at bevel for welding 9 places of terminal part 7 and belong to 25.
In this method, fill out alloy owing to form weldering, so the shape of bevel for welding 9 can freely determine with meltallizing.Certainly, also be applicable to the bevel for welding that adopts in the welding method of embodiment 1,2,3.
Adopt this method, weldering is filled out alloy 11 and can more be reduced the dilution rate of mother metal more near the groove shape.For example, fill out alloy 11 with ring-type weldering and compare, the Si amount in the weld metal 10 is increased, effectively prevent weld crack with identical basal area.
Effect of the present invention:
Above among described the present invention, make weldering fill out alloy molten with the high energy beam concentrated area, the dilution rate of mother metal for weld metal is limited in certain scope, so, can make being evenly distributed of Si in the weld metal or Mg. Therefore, welding method of the present invention can prevent from producing weld crack at the junction surface of aluminum conductor.
