Abstract
Description
本発明は、摩擦撹拌接合装置およびこれを用いた接合方法に関する。 The present invention relates to a friction stir welding apparatus and a joining method using the same.
摩擦撹拌接合（Friction Stir Welding: FSW）とは、円筒状のツールを回転させながら強い力で被接合部に押し付けることで、被接合部周辺を塑性流動により撹拌して、部材を接合する接合方法である。FSWは、被接合部材を溶融させないため、入熱が小さく、他の溶接法に比べて熱変形が小さいことが特徴の接合方法である。従来、FSWは鉄道車両構体のような、アルミニウムなどの軟質材料で薄板部材の接合に利用されてきた。 Friction Stir Welding (FSW) is a method of joining members by agitating the periphery of the welded part by plastic flow by pressing the cylindrical tool against the welded part with a strong force while rotating it. It is. FSW is a joining method characterized by low heat input and low thermal deformation compared to other welding methods because it does not melt the members to be joined. Conventionally, FSW has been used for joining thin plate members with a soft material such as aluminum, such as a railway vehicle structure.
近年、ツールの材料開発が進んだことで、FSWによる鉄鋼材料の接合や、厚板部材の接合が可能となってきた。したがって、今後は、FSWがステンレス鋼など腐食環境化で使用される材料の接合にも広く適用されることが期待される。 In recent years, with the development of tool materials, it has become possible to join steel materials and thick plates using FSW. Therefore, in the future, FSW is expected to be widely applied to the joining of materials used in corrosive environments such as stainless steel.
一方、鉄鋼材料のFSW接合では、アルミニウム等の軟質材料に比べて入熱が大きくなるために、FSWであっても、接合による引張残留応力の発生が懸念される。引張残留応力は、腐食環境化では、いわゆる応力腐食割れ（Stress Corrosion Cracking: SCC）を引起すことが知られているため、十分に考慮しておく必要がある。 On the other hand, in FSW bonding of steel materials, heat input is larger than that of soft materials such as aluminum, so there is a concern that tensile residual stress is generated by bonding even in FSW. The tensile residual stress is known to cause so-called stress corrosion cracking (（SCC) in a corrosive environment, and therefore needs to be fully considered.
従来技術として、特許文献１には、アーク溶接などの一般的な溶接において、溶接直後に接合部を急冷することによる引張残留応力の低減方法が記載されている。また、特許文献２には、FSWにおいて接合部を冷却することによる残留応力の低減について記載されている。
As a conventional technique, Patent Document 1 describes a method of reducing tensile residual stress by quenching a joint immediately after welding in general welding such as arc welding.
溶接直後の急冷による残留応力の低減方法では、FSWの場合、必ずしも十分な残留応力の低減効果が得られない場合がある。ここで、溶接直後の急冷による残留応力の低減は、被接合部表面と内部の温度差と、この温度差による熱膨張の違いにより起こる。上記の溶接直後の急冷による残留応力の低減方法では、円筒状のツールでの摩擦熱のみにより温度差を発生させているため、十分な残留応力の低減効果を得られない問題がある。そのため、適切に接合部への入熱量を増加させて、冷却時の表面と内部の温度差を大きくする必要がある。 In the case of FSW, the method for reducing residual stress by rapid cooling immediately after welding may not always provide a sufficient residual stress reduction effect. Here, the reduction of the residual stress due to rapid cooling immediately after welding occurs due to the difference in temperature between the surface of the bonded portion and the inside and the difference in thermal expansion due to this temperature difference. In the method for reducing residual stress by rapid cooling immediately after welding, a temperature difference is generated only by frictional heat with a cylindrical tool, so that there is a problem that a sufficient residual stress reduction effect cannot be obtained. Therefore, it is necessary to appropriately increase the amount of heat input to the joint and increase the temperature difference between the surface and the inside during cooling.
そこで、本発明の目的は、FSWにおいて、適切に被接合部への入熱量を増加させて、接合直後の急冷による引張残留応力の低減効果を大きくすることである。 Therefore, an object of the present invention is to increase the amount of heat input to the welded portion appropriately in FSW and increase the effect of reducing the tensile residual stress due to rapid cooling immediately after joining.
本発明の摩擦撹拌接合装置は、回転子を用いた摩擦攪拌接合において、前記回転子が通過した前記接合部を冷却する冷却装置を有するとともに、前記回転子の外周において接合部と対向する位置に回転子と共に回転する入熱手段を有することを特徴とする。 The friction stir welding apparatus according to the present invention includes a cooling device that cools the joint through which the rotor has passed in friction stir welding using a rotor, and at a position facing the joint on the outer periphery of the rotor. It has the heat input means rotated with a rotor, It is characterized by the above-mentioned.
本発明の摩擦撹拌接合装置によれば、冷却時の表面と内部の温度差が大きくなり、施工後の引張残留応力の低減効果を大きくすることができる。 According to the friction stir welding apparatus of the present invention, the temperature difference between the surface and the inside during cooling becomes large, and the effect of reducing the residual tensile stress after construction can be increased.
以下に本発明を、図面を用いて説明する。 Hereinafter, the present invention will be described with reference to the drawings.
本発明の実施例１を以下に説明する。図１は本発明の実施例１にかかる摩擦撹拌接合装置の模式図を示す。図１に示す摩擦撹拌接合装置では、回転子１がプローブ２を備えており、プローブ２が被接合部に圧入されている。プローブ２の取り付け部には、接合部周辺を塑性流動させて練り混ぜることで複数の部材を一体化させるための、ショルダ１１を有する。また、回転子１の進行方向に対して反対側に、冷却装置３を備えており、冷却材４により回転子１が通過した直後の被接合部表面５を冷却している。さらに、ドーナツ状の入熱手段６を回転子１の外側に備えている。入熱手段６は、被接合部に機械加工を施す加工面６ａで被接合部表面５に接しており、押付け機構６ｂの反力により押し付けられている。また、押付け機構６ｂは押さえ板６ｃにより固定されている。さらに、入熱手段６は保持具６ｄにより回転子１に固定されているため、回転子１の回転に伴って回転している。ここで入熱手段６としては、回転による摩擦熱により加工面６ａを加熱させる工具である。入熱手段６は、摩擦熱が大きい研磨が好適であるが、切削など他の加工工具を除外するものではない。
Example 1 of the present invention will be described below. FIG. 1 is a schematic diagram of a friction stir welding apparatus according to Example 1 of the present invention. In the friction stir welding apparatus shown in FIG. 1, the rotor 1 includes a
本装置によれば、回転子１の回転に伴って、被接合部表面５が、加工面６ａにより機械加工され、加工の摩擦熱が発生することで、入熱手段６を持たない従来の摩擦撹拌接合装置に比べて、被接合部表面５の温度を上昇させることができる。
According to this apparatus, as the rotor 1 rotates, the
図２は、本発明の原理を説明する被接合部の板厚方向の温度分布を示す模式図である。本装置による急冷前の板厚方向の温度分布７ａは、入熱手段を用いない従来法による急冷前の板厚方向の温度分布７ｂに比べて、摩擦熱により接合部表面で高温となる。この状態から、冷却材４により冷却されると、被接合部表面５の温度が低下するため、本装置による急冷直後の温度分布は、本装置による急冷直後の板厚方向の温度分布８ａのように、従来法による急冷直後の温度分布は、従来法による急冷直後の板厚方向の温度分布８ｂのようになる。このとき、本装置では、表面と内部の温度差ΔＴ1が、従来法によるΔＴ2に比べて大きくなる。その結果、表面と内部の熱膨張の差が大きくなることで、本装置では、従来手法に比べてＦＳＷ施工後の引張残留応力を大きく低下させることができる。
FIG. 2 is a schematic diagram showing the temperature distribution in the plate thickness direction of the bonded portion for explaining the principle of the present invention. The temperature distribution 7a in the plate thickness direction before quenching by the present apparatus becomes higher on the surface of the joint due to frictional heat than the
図３は、図１における斜視図である。本装置では、通常の接合によるビード５ａだけでなく、入熱手段６による加工痕５ｂが現れる。すなわち、ビード５ａの形状は従来法に比べて入熱手段６により平滑化される。したがって、本装置では、残留応力の改善のみならず、ビード５ａが平滑化され、応力集中が小さくなることによる、疲労強度などの改善も期待できる。
FIG. 3 is a perspective view of FIG. In this apparatus, not only the
このように、本発明によれば、ＦＳＷ施工後の引張残留応力を、従来法に比べて低下させることができるとともに、ビード形状を平滑化することができる。 Thus, according to the present invention, the tensile residual stress after the FSW construction can be reduced as compared with the conventional method, and the bead shape can be smoothed.
次に、図４は実施例２にかかる摩擦撹拌接合装置の模式図を示す。以下では、実施例１と同一の記号の説明は省略する。実施例２は、回転子１が被接合部表面５に対して傾けて施工する場合の例である。回転子１を傾ける場合でも、入熱手段６の加工面６ａを、予め、回転子１の傾き角に合わせた所定の角度に成形しておくことで、進行方向の後方の被接合部表面５を加工面６ａによって加工することができる。
Next, FIG. 4 shows a schematic diagram of the friction stir welding apparatus according to the second embodiment. In the following, description of the same symbols as those in the first embodiment is omitted. Example 2 is an example in the case where the rotor 1 is constructed while being inclined with respect to the
したがって、接合部表面の温度が上昇することで、冷却による残留応力の改善効果を高めることができる。 Therefore, the effect of improving the residual stress due to cooling can be enhanced by increasing the temperature of the surface of the joint.
図５は実施例３にかかる摩擦撹拌接合装置の模式図を示す。実施例３は、入熱手段６による入熱を制御する、入熱制御装置９を持つ。入熱制御機構９は、加力板９ａ、転動部９ｂ、電動アクチュエータ９ｃ、荷重計測装置９ｄ、熱電対９eおよびコントローラで構成されている。入熱制御装置９は荷重計測装置９ｄの位置で固定されており回転せず、回転する入熱手段６とは転動部９ｂを介して接している。実施例３では、熱電対９ｅにより常に進行方向後方の温度を計測している。さらに、電動アクチュエータ９ｃの押し込み量を調節することで、加工面６ａの接触力を制御できる。すなわち、被接合部表面５の温度が、予め求めておいた最適な急冷前の温度となるように、コントローラにより制御することができる。
FIG. 5 is a schematic diagram of the friction stir welding apparatus according to the third embodiment. The third embodiment has a heat
このように、本発明によれば、ＦＳＷ施工後の引張残留応力を、従来法に比べてより適切に低下させることができるとともに、ビード形状を平滑化することができる。 Thus, according to the present invention, the tensile residual stress after the FSW construction can be reduced more appropriately than the conventional method, and the bead shape can be smoothed.
図６は実施例４にかかる摩擦撹拌接合装置の模式図を示す。実施例４は、入熱制御装置９が、ヒータ１０をもつ。ヒータ１０は、箱形の加力板の内部に備えられている。実施例４では、ヒータ１０により入熱手段６を加熱することで、入熱手段６から被接合部表面５への入熱を大きくすることができる。
FIG. 6 is a schematic diagram of the friction stir welding apparatus according to the fourth embodiment. In the fourth embodiment, the heat
本発明は、腐食環境で使用され、引張残留応力によるＳＣＣが問題となる材料である、ステンレス鋼などの接合において好適である。また、変形が拘束されて引張残留応力が発生しやすい、板厚の厚い部材の接合に好適である。 The present invention is suitable for joining stainless steel or the like, which is a material that is used in a corrosive environment and causes SCC due to tensile residual stress. Further, it is suitable for joining thick members that are easily deformed and easily generate tensile residual stress.
なお、本発明の入熱手段の材質は、熱容量が大きく熱が逃げにくい材料が好適であり、例えばステンレス鋼などが好適である。また、本発明の入熱手段の加工方法は、摩擦熱が大きい研磨が好適であるが、切削など他の加工方法を除外するものではない。また、上記の実施例では加工具の押付け機構にコイル式のバネを用いた例を示したが、板バネなど反力が発生する他の機構を用いてもよい。 In addition, the material of the heat input means of the present invention is preferably a material having a large heat capacity and difficult to escape heat, such as stainless steel. Further, the processing method of the heat input means of the present invention is preferably polishing with large frictional heat, but does not exclude other processing methods such as cutting.
