2.  GLOBAL HYDROGEN BRAZING MARKET — OVERVIEW

2.1  What Is Hydrogen Brazing?

Hydrogen brazing is a specialized metal-joining technique in which a filler metal with a lower melting point than the base materials is melted and flowed into the joint through capillary action under a controlled hydrogen atmosphere. Unlike conventional brazing methods, hydrogen brazing does not require flux; instead, the hydrogen atmosphere functions as a reducing agent that prevents surface oxidation, removes pre-existing oxide films, and ensures clean, bright joints.

The process is conducted inside sealed furnaces at elevated temperatures, typically ranging from 600°C to over 1,100°C depending on the filler metal and base material combination. Two primary variants define the market: dry hydrogen brazing, which uses pure dry hydrogen with very low dew points (typically below −40°C), and wet hydrogen brazing, which introduces controlled moisture content into the gas stream to modulate the reducing potential.
