| Abstract: | In this paper the characteristics and applications of the martensite precipitation-hardening stainless steel （15-5 PH） are introduced, and technical experiments of vacuum electron beam （EB） welding of the material is discussed in detail. The result of X-ray defect detection indicates that the quality of welded joint satis-fied a national military standard of first grade, and the mechanical performance of the welded joint at room temperature satisfied all requirements. These validated excellent vacuum electron beam（EB） welding capability of the material. The welding method was successfully used for manufacturing the antenna pedestal of a certain product. |
