Hydrogen Brazing

Bluewater’s Hydrogen Brazing technique is one of our most popular atmospheric brazing methods.  When exercising this method of brazing, we place the metals to be joined in the brazing furnace and heat it to the point wherein the brazing alloy being utilized melts and flows between two parts to form a seamless metallurgical joint. Bluewater offers two methods of Hydrogen Brazing: Wet Hydrogen Brazing and Dry Hydrogen Brazing. Since the byproducts of burning hydrogen (H2) are two sanitary agents: heat and water, a Wet Hydrogen Atmosphere is most often used by our technicians to remove residual oxides, hydrocarbons and other contaminants. These byproducts eliminate the need for a flux to remove any impurities because they already accomplish a high-temperature, sanitary flush of those metal parts being heated. Bluewater’s Wet Hydrogen Atmospheres are most often employed on materials like copper and steel because these metals are more compatible with higher dewpoints.

There are other materials which necessitate the use of a Dry Hydrogen Atmosphere because they are susceptible to forming impure oxides at even the lowest of humidity levels. Stainless Steel, Tungsten and Moly are a few of those materials which cannot tolerate a Wet Hydrogen Atmosphere. No matter which method Bluewater applies, our Hydrogen Brazing techniques will ensure a successful braze across the entire amalgamated surface of the two components being assembled and provide an airtight seal with enhanced thermal conductivity.

Hydrogen Brazing Properties:

  • Due to the byproducts of the hydrogen process, parts emerge ultra-bright and ultra-clean, free of oxides and contaminants
  • Assembled parts have optimized thermal conductivity and strong, airtight seals
  • The byproducts of Hydrogen Brazing eliminates the need for fluxes to protect the braze joint surfaces from contaminants
  • Allows for precise control over the brazing cycle

Hydrogen Brazing Applications:

  • For brazing metals and ceramic to metal assemblies
  • For stainless and carbon steel assembles
  • Stainless steel, tungsten, copper, steel and moly parts
  • Parts that require a precise, clear-cut joint temperature
  • Electron beam devices, vacuum tubes, medical devices, fuel lines, torque converters, and semiconductor devices
