本発明は、酸化物分散型白金製品の部材溶接方法の改良
に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a method for welding members of oxide-dispersed platinum products.
（従来の技術）

が厄介になるからである。(Prior art) Conventionally, Pt-ZrO7, which is oxide-dispersed reinforced platinum,
To weld parts of products made of t-Y2O3, Pt-Th○2, etc., for example, to weld a vibrator 2 to the bottom side of the glass welding device 1 shown in FIG. Welding was carried out using a welding rod made of platinum. This is because welding using welding rods of different metals makes regeneration and refining difficult.
（発明が解決しようとする課題）
ところで、上記の溶接方法では、溶接棒の溶融時分数し

酸化物分散型白金製品の使用中に溶接部が熱と応力によ
り破損することがあって、寿命が短かった。(Problem to be Solved by the Invention) By the way, in the above welding method, the oxide that has been melting in the welding rod rises to the surface of the weld zone, and the properties of the oxide-dispersed reinforced platinum are lost, causing mechanical problems. The strength of the target becomes weaker,
During use of oxide-dispersed platinum products, the welded parts were sometimes damaged due to heat and stress, resulting in a short service life.
そこで本発明は、使用中に溶接部が熱と応力により破損
することが無いようにした酸化物分散型白金製品の部材
溶接方法を提供しようとするものである。SUMMARY OF THE INVENTION Therefore, the present invention provides a method for welding parts of oxide-dispersed platinum products in which the welded parts are not damaged by heat and stress during use.

を用いて部材を溶接することを特徴とするものである。(Means for Solving the Problems) In order to solve the above problems, the method for welding parts of oxide-dispersed platinum products of the present invention provides a method for welding parts of products made of oxide-dispersed platinum. The method is characterized in that members are welded using a platinum alloy welding rod containing 0.5 to 5 wt% of the same metal as the dispersed element.

強度を向上させる為で、０．５ｗｔ％以下ではその効果

である。The reason why the composition of the welding rod used in the member welding method of the present invention is a platinum alloy containing 0.5 to 5 wt% of the same metal as the element dispersed as an oxide in the base material is that the welding rod is melted. This is to improve the mechanical strength of the welded part when the component is welded to the base material, and if it is less than 0.5 wt%, there is no effect, and if it exceeds 5 wt%, it becomes difficult to form.

無い。(Function) The method for welding parts of oxide-dispersed platinum products of the present invention is to weld 0.5 to 0.5 to
Since parts are welded to oxide-dispersed platinum products using a platinum alloy welding rod containing 5 wt%, oxides do not rise to the surface of the weld as in the conventional method, reducing the mechanical strength of the weld. Nothing happens. Therefore, the welded part will not be damaged by heat and stress during use of the oxide-dispersed platinum product.

Compared to the welded part where the vibrator 2 is welded to the bottom side surface of the glass melting apparatus 1, it can be seen that the time required for breakage is an order of magnitude longer and the mechanical strength, especially the heat resistance, is excellent.
