I will explain the basic steps of atmosphere brazing with plenty of illustrations.
【Procedure for Atmosphere Brazing】 1. Clean the materials 2. Place the filler metal 3. Assemble 4. Put into the furnace 5. Heat 6. Cool 7. Inspect 8. Completion This is the flow. In other words, "It is the technique of melting a metal bond in the furnace to connect parts!"
Introduction to the characteristics of "hydrogen atmosphere" and "vacuum atmosphere."
We would like to introduce "Brazing Method 1 - Atmosphere Brazing" from the easy-to-understand "Brazing" series. Atmosphere brazing is classified into "hydrogen atmosphere" and "vacuum atmosphere." The "hydrogen atmosphere" uses hydrogen. The "vacuum atmosphere" performs brazing in a rarefied atmosphere evacuated by a vacuum pump. 【Hydrogen Atmosphere Features】 ■ It has a strong reducing power against metal oxides. ■ At high temperatures, low dew point hydrogen gas can reduce oxides of stainless steel, iron, chromium, copper, nickel, and others. ■ Oxides of metals containing titanium and aluminum cannot be reduced. ■ The dew point refers to the moisture content in hydrogen gas, and the lower it is, the higher the reducing power. ■ Hydrogen has good thermal conductivity and is environmentally friendly. *For more details, please refer to the PDF materials or feel free to contact us.
