The electron beam welding of dissimilar materials - case study

[摘要] The modalities to realize the welding workpieces are multiple. The electron beam welding is one of them. One can weld two different types of materials that give the possibility to reduce the cost of workpiece, if the active part is realised of rich materials welded on components with inferior phisico-mecanical characteristics. The procedure provides great flexibility to the product designs through efficient use of each type of material. So this aspects lead to the necessity to join dissimilar metals. Different tables are given in the specific literature regarding the possible combination. Conflicts may arise by the compromises required for to the optimum heat control of the two dissimilar materials used. But nowadays, more and more frequently are meet the welding of dissimilar metals, thus, the objective of this article is to provide information regarding the particular case of welding between stainless steel and copper without the filler material use.
