Easy-to-understand brazing series: Differentiating between hydrogen furnaces and vacuum furnaces
[Question] How do you decide on the use of different brazing equipment?
**Answer** The choice depends on the weight and size of the workpiece, as well as the type of base material. Hydrogen furnace → for small and lightweight items Vacuum furnace → for large and heavy items. Let's remember this. The features and compatible metals are as follows: ◆ Hydrogen furnace - Utilizes the reducing power of hydrogen - Iron, copper, and nickel can be reduced - Titanium and aluminum can hardly be reduced - Tough pitch copper is unsuitable due to hydrogen embrittlement ◆ Vacuum furnace - Removes metal oxides through a thin atmosphere (referred to as "thermal dissociation") - Also compatible with titanium and aluminum We will provide a clear explanation with diagrams in the PDF materials.
