| Abstract: | Designing performance,manufacture methods and basic parameters of laser welding transition layer powder A are presented in this paper.Mechanical properties of powder A sintered samples,laser welding intensity of transition layer A and transition layer made by a overseas company bonded with 50Mn2V steel substrate are investigated.The results indicate that transition layer A sintered between 780℃ and 880℃ is better than transition layer of certain overseas company in security and stabilization and can be applied for different working layers.Moreover,the welding intensity of transition layer A has met and surpassed the BS En13236：2001 standard on safety.Therefore,the laser welding transition layer powder from the overseas can be replaced by the powder A. |
