【発明の詳細な説明】
本発明は、接点材溶接用電極の改良に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in electrodes for welding contact materials.
従来、接点材を台材にシーム溶接やスポツト溶
接等を行なう為に使用する電極は、Cu−Cr、Cu
−Ti、Ag−Ｗ、Ｗ、Mo等の材料により構成さ
れていた。 Conventionally, the electrodes used to perform seam welding, spot welding, etc. of contact materials to base materials are Cu-Cr, Cu
-It was composed of materials such as Ti, Ag-W, W, and Mo.
然し乍ら、Cu−Cr、Cu−Ti、Ag−Ｗ等の比
較的融点の低い材料を使用した電極は、溶接時に
発熱する熱により一部が溶け出して接点材の接点
面に付着し、これが酸化或いは硫化して接点の接
触抵抗を増大してしまうという欠点があつた。ま
た一方Mo、Ｗ等の高融点の材料を使用した電極

が、極めて酸化し易い為、溶接時の発熱により接
点と接触する部分が酸化してしまい、その結果接
点材と電極との接触抵抗が不安定となる。従つて
接点材の溶接時の溶接条件がその都度異なり、溶
接強度にばらつきが生じるという欠点があつた。 However, with electrodes made of materials with relatively low melting points such as Cu-Cr, Cu-Ti, and Ag-W, a portion of the electrodes melts due to the heat generated during welding and adheres to the contact surface of the contact material, causing oxidation. Alternatively, it has the disadvantage that it becomes sulfurized and increases the contact resistance of the contacts. On the other hand, electrodes made of materials with high melting points such as Mo and W can prevent melting due to heat generated during welding, but they are extremely susceptible to oxidation, so the parts that come into contact with the contacts may oxidize due to the heat generated during welding. As a result, the contact resistance between the contact material and the electrode becomes unstable. Therefore, the welding conditions when welding the contact materials differ each time, resulting in a disadvantage that the welding strength varies.

せんとするものである。 The present invention has been made to eliminate such drawbacks, and is capable of preventing a portion of the electrode from melting due to heat generation during contact material welding, and stabilizing the contact resistance with the contact material during contact material welding. An object of the present invention is to provide an electrode for contact material welding that can maintain high and stable welding strength.

被覆して成るものとがある。 The electrode for welding a contact material according to the present invention is an electrode that welds a contact material to a base material by seam welding, spot welding, etc., and at least the part that comes into contact with the contact material is made of a noble metal or precious metal that has a higher melting point than the contact material. It is characterized by being made of alloy. That is,
The contact material welding electrode of the present invention includes at least a contact material made of only a noble metal or a noble metal alloy having a higher melting point than the contact material, and an electrode made of Cu-Cr, Cu-Ti, Ag-W, W, Mo, etc. A noble metal or noble metal alloy with a higher melting point than the contact material is applied to the part that comes into contact with the contact material.
Some are coated by means such as plating vapor deposition or ion plating.

する為である。さらに詳しく説明すると、通常接
点材と台材との接触抵抗は、電極と台材或いは接
点材との接触抵抗よりも高いので、この間に溶接
電流を流すと、接点材と台材とが互に溶け出して
接合されるが、電極と接点材或いは電極と台材も
接触しているので通電により電圧が降下し、この
間でも発熱が起きる。この場合接点材よりも融点

で、これを防止する為に電極の少くとも接点材と
接触する部分に、接点材の融点よりも高い貴金属
又は貴金属合金を配するものである。 In the contact material welding electrode of the present invention, the reason why a noble metal or a noble metal alloy having a higher melting point than the contact material is arranged at least in the part that contacts the contact material is as follows.
This is to prevent part of the electrode from melting and adhering to the contact surface of the contact material when welding the contact material to the base material using the electrode. To explain in more detail, the contact resistance between the contact material and the base material is usually higher than the contact resistance between the electrode and the base material or the contact material, so when welding current is passed between them, the contact material and the base material Although they are melted and bonded, since the electrodes and the contact material or the electrodes and the base material are also in contact with each other, the voltage drops due to energization, and heat generation occurs during this time as well. In this case, if the electrode is made of a material with a lower melting point than the contact material, it will partially melt and adhere to the contact material, staining the contact surface of the contact material. A noble metal or noble metal alloy whose melting point is higher than that of the contact material is placed in the part that comes into contact with the contact material.
かように構成された本発明の接点材溶接用電極
によれば、接点材を台材に溶接する際、電極が接
点材の接点面に直接接触しても接点面を汚すこと
なく溶接できる。また電極の酸化や硫化等が生じ
ないので、溶接時の電気的条件を一定にすれば、
電極と接点材の接触抵抗が安定していることから
流れる電流は一定となり、溶接後の接点材と台材
との溶接強度は高く安定したものにできる。 According to the contact material welding electrode of the present invention configured as described above, when welding the contact material to the base material, even if the electrode directly contacts the contact surface of the contact material, welding can be performed without staining the contact surface. In addition, since oxidation and sulfidation of the electrode do not occur, if the electrical conditions during welding are kept constant,
Since the contact resistance between the electrode and the contact material is stable, the flowing current is constant, and the welding strength between the contact material and the base material after welding can be made high and stable.

When a sulfurization test was conducted on 20 of these electrical contacts, there was no discoloration of the contact material and no copper sulfide was generated. However,
Electrical contacts were made by seam welding the contact material to the base material using a conventional contact material welding electrode made only of Cu-Cr, and a sulfurization test was conducted on 20 electrical contacts. The surface of the
Analysis of this discolored area revealed that it was copper sulfide. In other words, with conventional contact material welding electrodes, part of the electrode melts and adheres to the contact material during welding of the contact material, but with the contact material welding electrode of the present invention, part of the electrode melts during welding of the contact material. It can be seen that no discharge occurs at all.

の効果がある。 As described in detail above, according to the electrode for welding contact materials according to the present invention, a part of the electrode does not melt due to the heat generated during welding of the contact material, so the contact surface is not contaminated, and the electrode is not oxidized or sulfurized. Therefore, by keeping the welding conditions constant, the contact resistance between the electrode and the contact material becomes stable, and the flowing current becomes constant, which has the effect of making it possible to maintain a high and stable welding strength of the contact material.
