Brazing with a vacuum furnace and welding with an electron beam! High-quality joining technology.
At Nikko-shi, we undertake joining processing. "Vacuum brazing" is a brazing process conducted in high vacuum, allowing for a clean brazing without discoloration. "Electron beam welding" is a method that uses an electron beam in a vacuum to melt metal for welding, resulting in a narrow molten width and deep penetration.
