  • the parts already developed can be used and now secured with better adhesion and a guarantee of staying with time higher than with bonding.
  • the ceramic-based or silicon-based parts do not have to have elastic or plastic deformation means that prevent them from being broken by an assembly because the welding directly affixes the surfaces of the ceramic or silicon-based parts against surfaces metal-based parts.
