Abstract
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.
