Hydrogen Brazing Services img_3140Hydrogen furnace brazing is a technique where brazing is accomplished in a pure hydrogen atmosphere without flux. This process is used for many alloys, including carbon steel, copper and stainless steel. Hydrogen is used as a reducing agent to remove the metal oxides and as a result, parts are bright and clean after processing. Hydrogen brazing creates durable, flux-free joints of high structural integrity and allows for hardening or heat treating after brazing. The ability of hydrogen to reduce the metal oxides on the surface is determined by temperature, hydrogen gas purity and pressure. Hydrogen furnace brazing is done in a pure dry hydrogen gas atmosphere at a slightly positive pressure in a vacuum furnace. The brazing temperature is dependent on the base metal being joined and the filler metal used in the brazing process. Uniform heating in the furnace allows even complex shapes to be brazed with little distortion. Rigorous temperature uniformity is maintained on the part while being heated, drastically reducing the residual stresses by carefully controlling the heating and cooling cycle. California Brazing specializes in hydrogen brazing and can apply this process to whatever task required, no matter how large or difficult.

Vacuum Aluminum Brazing vacuum-brazingAluminum vacuum brazing is typically accomplished in a vacuum furnace and used for very high reliability brazing applications. It is a fluxless, clean process where the braze filler material is usually preplaced in the joint and is 100% dense. Vacuum brazing creates a joint with strong structural integrity that will not destruct under intensive pressure. The joint can be machined after brazing, even drilled. Aluminum vacuum brazing is most successful when the part design has a flat surface. This is because pressure needs to be applied in order to break down the oxide layer in the aluminum so that the filler metal can melt and diffuse past the oxide layer into the base metal. In aluminum vacuum brazing, there is no post-braze cleaning. However, more precise machining prior to the vacuum process is required.
