3 Terms and Definitions

ISO 1942 and ISO 22674 as defined in the following terms and definitions apply to this document. 3.1 Laser welding laserwelding In the case where no metal or the filler material (welding), the laser beam as a heat source, a metal material same or different kind of The method of connecting to produce fusion zone by melting metal, the metal together form a connection. 3.2 Brazing brazing The method of using a heated metal brazing material as a filler material, method of metal material same or different kind of connected. Note 1. As used liquidus temperature of the brazing material is greater than 450 ℃, but less than the melting range brazed metal material. Brazing material by capillary action seepage To be welded into the gap between the metal material in the metallurgical combination of the metal material to be welded are connected. Note 2. Unlike brazing fusion welding, brazing is not required because the molten metal being welded.
