本発明は導電性母材の接合部を、通電加熱によ
る抵抗発熱と加圧による塑性変形によつて一体化
する通電加熱圧接において、特に加熱圧接部の品
質を自動的にかつ容易に保証、管理し得るように
した加熱圧接部の自動評価装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention automatically improves the quality of the heat-welded parts in electrical heat-pressure welding, in which the joints of conductive base materials are integrated by resistance heat generation caused by current heating and plastic deformation caused by pressurization. The present invention relates to an automatic evaluation device for heat-pressure welded parts that can be easily guaranteed and managed.
従来、銅と銅あるいは銅とアルミニウム等、導
電性母材同士を接合する方法としては種々のもの
があるが、その接合の物理的な原理は接合部をい
かに清浄に保ち、かつ接合する母材の原子同士の
配列を何んらかのエネルギーを加えることによつ
て、高品質の接合部（継手）を如何に容易に得る
かである。 Conventionally, there are various methods for joining conductive base materials such as copper and copper or copper and aluminum, but the physical principle of joining is how to keep the joint clean and the base materials to be joined. The question is how to easily obtain high-quality joints by applying some energy to the arrangement of the atoms in the structure.
一方、これらの接合方法にはエネルギーの加え
方によつて種々のものがあるが、大別すると接合
部の材料が固相が液相、或いは加圧が必要か否か
によつて融接・圧接およびろう接に分けられる。
このうち、圧接接合法は他の２つの方法とは異な
り、接合しようとする母材自体が加圧のみか加熱
と加圧によつて一体化しようとする方法であるた
め、その接合部の品質評価には他の方法による接
合部の非破壊検査技術をそのまま適用することは
難かしい。すなわち、他の融接やろう接方法では
接合部に溶融による組織の粗大化や異材があり、
ある種の不連続部ができるが、圧接方法では加圧
のみか加圧と加熱の併用によつて接合するため、
接合部は一体化しある種の不連続部も極めて限ら
れた面しかない。このため、従来の評価方法とし
ては破壊試験で確認し、確率的に保証するように
しているのが一般的である。 On the other hand, there are various joining methods depending on how energy is applied, but they can be roughly divided into fusion welding, Divided into pressure welding and soldering.
Of these, the pressure welding method differs from the other two methods in that it attempts to integrate the base materials themselves by applying pressure alone or by heating and pressurizing, so the quality of the joint is high. It is difficult to directly apply non-destructive inspection techniques for joints using other methods for evaluation. In other words, with other fusion welding and brazing methods, there may be coarsening of the structure or foreign materials at the joint due to melting.
Some discontinuities may occur, but with the pressure welding method, the bond is made using only pressure or a combination of pressure and heating.
The joints are integrated, and some discontinuities are very limited. For this reason, the conventional evaluation method is to confirm by destructive testing and to guarantee it probabilistically.
上述したように、再現性の良い加熱圧接方法で
はその接合部が非常に狭く且つ同種一体化したも
のであるため、適切な接合条件を破壊試験で評
価、確認しながら決定するが、確率的に保証する
以外に品質の保証を現状の非破壊試験にて判定す
ることは非常に難かしい。 As mentioned above, in the heat pressure welding method, which has good reproducibility, the joint is very narrow and the same type of material is integrated. It is extremely difficult to determine quality assurance through current non-destructive testing.
一方、従来圧接接合した接合部の品質は、破壊
試験で品質を確認し、再現性のよいことから同一
結果がある数得られれば良いものとされている。
然し乍ら、今後は高品質の継手部に多く使用され
るようになり、従来よりもグレードの高い品質が
要求されるため、一継手毎に品質を安定させるこ
とが必要である。 On the other hand, the quality of conventional pressure-welded joints is confirmed by destructive testing, and because of good reproducibility, it is said that it is sufficient to obtain the same result a certain number of times.
However, in the future, it will be used more often in high-quality joints, and a higher grade of quality than before will be required, so it is necessary to stabilize the quality of each joint.
本発明はかかる事情に鑑みて成されたもので、
その目的は加熱圧接により得られる加熱圧接部の
品質を自動的にしかもより確実に保証、管理する
ことができる加熱圧接部の自動評価装置を提供す
ることにある。 The present invention was made in view of such circumstances,
The purpose is to provide an automatic evaluation device for heat-welded parts that can automatically and more reliably guarantee and manage the quality of heat-welded parts obtained by heat-pressure welding.
本発明では、加熱圧接法においてその加熱圧接
部の品質を最も左右する制御要因が接合部の通電
加熱状況であることに着目し、この通電加熱状況
（通電力量）を把握することによつて、上記目的

部に通電加熱させながら加圧して塑性変形させ、

トにより一定に保ち、品質の安定を管理しようと
するものである。 In the present invention, we focus on the fact that the control factor that most influences the quality of the heat-pressure welded part in the heat-pressure welding method is the energization heating state of the joint, and by understanding this energization heating state (the amount of power applied), This aims to achieve the above objectives. In other words, the joint is electrically heated and pressurized to cause plastic deformation.
In the case of the heat pressure welding method, in which the joint is extruded and flowed toward the outer periphery, the quality of the joint is greatly influenced by the current heating conditions, so the current heating conditions are kept constant by presetting to manage quality stability. It is something.
