蔽材しながら溶接する円筒体の電子ビーム溶接法に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electron beam welding method for a cylindrical body, and more particularly to an electron beam welding method for a cylindrical body, in which the electron beam that has passed through the welded part is welded while being shielded by an electron beam shielding material. .
従来、たとえば第１図Ａ，Ｂに示すように円環１を電子
ビーム溶接法で、溶接部２を溶接して製造するにあたっ
ては、溶接部２に電子ビームを当てると、電子ビームが
溶接部２を貫通し、この貫通した電子ビームが下部３ま
でを溶融してしまうので、妥当Ａを用いて貫通した電子
ビームを遮蔽していた。Conventionally, when manufacturing a ring 1 by welding a welded part 2 using an electron beam welding method as shown in FIGS. 1A and B, for example, when an electron beam is applied to the welded part 2, the electron beam is 2, and this penetrating electron beam melts the lower part 3, so the probability A was used to shield the penetrating electron beam.
髪当Ａには鋼板などが通常用いられるが、溶接部の形状
に応じて、その都度裏当を作成しなければならず、円筒
体のように被溶接物が筒状の場合には、裏当の設置が困
難であり、かつ溶接終了後に妥当の取出しが不可能にな
るなどの欠点があつた。A steel plate or the like is usually used for the hair rest A, but a backing must be created each time depending on the shape of the welded part. There were drawbacks such as the installation being difficult and the removal being impossible after welding was completed.
そこで本発明は、かかる従来の欠点を解消すべ〈なされ
たものであり、本発明の円筒体の電子ビーム溶接法は、
被溶接個所の内部に粉末状，粒状または繊維状金属から
なる流動状の電子ビーム遮蔽材を充填し、溶接部を貫通
した電子ビームをこの遮蔽材により遮蔽しつつ溶接する
ことを特徴とするものである。Therefore, the present invention has been made to eliminate such conventional drawbacks, and the electron beam welding method for cylindrical bodies of the present invention is
The part to be welded is filled with a fluid electron beam shielding material made of powdered, granular, or fibrous metal, and the electron beam that penetrates the welding part is shielded by this shielding material during welding. It is.
以下、本発明を図面に示した実施例にもとづき説明する
。The present invention will be described below based on embodiments shown in the drawings.
第２図Ａ，Ｂにおいて、被溶接部材は円筒体１０，１０
′で示してある。In FIGS. 2A and 2B, the members to be welded are cylindrical bodies 10, 10.
’ is indicated.
そして両円筒体は溶接接合面に近い個所で部材１１，１
１′で仮に封じておき、その空間内に電子ビーム遮蔽材
６を充填し、熔接部２を電子ビーム溶接する。その結果
、溶接部２を貫通した電子ビームは遮蔽材６で遮蔽しつ
つ、溶接することができる。そしてこの場合、第３図Ｂ
に示す如く、円筒体１０，１０′を矢印Ａの方向に回転
させれば、電子ビーム遮蔽材６は常に円筒体１０，１０
′の下部に保持されると云う便利さがある。なお、本発
明に用いる電子ビーム遮蔽材は、金属粉や金属製カット
ワイヤなどの流動性を有するものであることが必要で、
そのような電子ビーム遮蔽材を充填して電子ビーム溶接
をするものであるから、本発明によれば、溶接部を貫通
した電子ビームが電子ビーム遮蔽材で遮蔽されるので、
溶接部下部の被溶接物が貫通した電子ビームにより溶融
することを完全に防止することができる。Both cylindrical bodies have members 11 and 1 near the welded joint surface.
1', the space is filled with an electron beam shielding material 6, and the welded portion 2 is electron beam welded. As a result, welding can be performed while the electron beam passing through the welding part 2 is shielded by the shielding material 6. And in this case, Figure 3B
As shown in FIG.
It has the convenience of being held at the bottom of '. Note that the electron beam shielding material used in the present invention needs to be fluid, such as metal powder or metal cut wire.
Since electron beam welding is performed by filling such an electron beam shielding material, according to the present invention, the electron beam that penetrates the welding part is blocked by the electron beam shielding material.
It is possible to completely prevent the object to be welded below the welding portion from being melted by the penetrating electron beam.
また、本発明で用いる電子ビーム遮蔽材は粉末状、粒状
、または短繊維状などの流動状のものであるから、溶接
終了後に、被溶接物に、たとえばくりぬき部を予め設け
ておき、溶接終了後にそこから取出し、これを容易に回
収することができる。しかも、この回収した電子ビーム
遮蔽材を、次の電子ビーム溶接の遮蔽材として再使用す
ることもできるので、極めて経済的である。Furthermore, since the electron beam shielding material used in the present invention is in a fluid form such as powder, granules, or short fibers, it is also possible to prepare a cutout in the workpiece after welding is completed. It can then be removed from there and easily recovered. Moreover, this recovered electron beam shielding material can be reused as a shielding material for the next electron beam welding, which is extremely economical.
更にかかる電子ビーム遮蔽材は、粉末状、粒状、または
短繊維状なので、被溶接物の形状変化にもかかわらず、
使用することができる便利さがあり、特に本発明のよう

するときには、電子ビーム遮蔽体６は流動して常に円筒
体の下部に集まり、少ない量でも遮蔽効果を充分果すこ
とができるものであり、更にまた従来のように被溶接物
の形状に応じて髪当を準備するわずらわしさが全くない
。Furthermore, since such electron beam shielding materials are in the form of powder, grains, or short fibers, they can be
Especially when welding a cylindrical body while rotating the cylindrical body as in the present invention, the electron beam shield 6 flows and always gathers at the bottom of the cylindrical body. Even with a small amount, a sufficient shielding effect can be achieved, and there is no need to prepare a hair rest according to the shape of the object to be welded, unlike the conventional method.
