Brazing requires the removal of the oxide film! The method for removing the oxide film differs between the atmosphere and the furnace.
From the easy-to-understand "Brazing" series, we introduce "Atmospheric Brazing and Furnace Brazing." Brazing first requires the removal of the oxide film. By removing the oxide film, the "braze" can wet properly. "Atmospheric brazing" requires flux, which acts to remove the oxide film on the surface of the base material. "Furnace brazing" removes the oxide film on the surface of the base material by creating an atmosphere of hydrogen gas or vacuum inside a furnace that blocks the atmosphere. 【Features of Atmospheric Brazing】 ■ Easy to perform while visually monitoring ■ Localized heating is possible ■ Can perform insert brazing and surface brazing ■ Suitable for small-scale production *For more details, please refer to the PDF document or feel free to contact us.

Company information
"Brazing" is a technique that involves flowing "molten metal filler" between base materials and cooling it to join them. The base materials and the filler are firmly bonded at the atomic level. 【Brazing is a familiar joining technology】 Brazing is used in parts for automobiles, air conditioners, gas water heaters, tools, and more. It is widely useful in fields such as machining and pipe processing. 【Advantages of Brazing】 ● Can join thin sheets and achieve precise connections ● Can join multiple points simultaneously ● Can join dissimilar metals and non-metals ● Can create complex shapes that cannot be made through cutting or grinding ● Can achieve high airtightness in joints While "welding" is a technique that joins materials by melting the base material, "brazing" is a technique that joins materials with little to no melting of the base material, making it suitable for joining delicate parts such as small items and thin sheets.
