激光淬火预处理后40Cr/T10A钢的固相焊接

Solid-phase welding between 40Cr and T10A after surface laser quenching

    摘要
  • 摘要: 探讨了结构钢40Cr与工具钢T10A待焊接表面激光淬火处理后进行固相焊接的可行性及影响因素。试验表明,钢的待连接面经激光淬火处理后,表层组织显著细化,然后在37~56.6MPa的预压应力、750~780℃的压接温度下,经5~7.5min短时保温即可实现接头抗拉强度达到母材强度的40Cr/T10A钢的固相焊接。

     

    Abstract: The feasibility and the influencing factors of solid phase welding between the structural steel 40Cr and tool steel T10A were explored under the condition of the surfaces to be laser quenched.The results show that super fine grain on sarface can be gotten after the pretreatment of surface laser quenching.With the condition of pre pressed under 37~56.6 MPa at the welding temperature of 750~780℃,the strength of joint is up to or close to that of base metal in a short time pressure welding.
