Metal Surface Processing Technology with CW Single-Mode Fiber Laser and Application for Joining Metals and Dissimilar Materials

Joining technology for metals and dissimilar materials is attracting attention in various industrial fields.In the automotive industry, the joining metals and plastics is especially expected to be a key technology for weight reduction.A new joining technology of metal to plastics has been developed by laser surface processing to metal.Such processing is done by a continuous-wave (CW) single-mode fiber laser.In this paper, we introduced the results of studies aimed at the mechanism's solution of unevenness formation in metal surface processing technology (DLAMP ® ) with a CW single-mode fiber laser and an airtight mechanism's solution for joining metal and resin.
