commercial heat treatment shops usually do not have this type of furnace. The exception is <strong>Galvamet<\/strong> with furnaces from <strong>TAV Vacuum Furnaces<\/strong>. But even that is not enough. There is another reason, probably even more significant, why aerospace does its brazing in-house.<\/p>\n<p>This reason is the demands on preparing parts for brazing, the most important part of the brazing process. Brazing itself is a very simple process if we have the right furnace, but without that preparation, the furnaces are useless.<\/p>\n<p>First, we must ensure perfect surface cleanliness, then correctly apply the right brazing matertial, and last but not least, correctly assemble the parts into a brazing assembly. For some applications, it is a big science. And since these activities cannot be fully automated, then reproducibility depends significantly on people and manual activities. I personally once transferred the technology of brazing with nickel brazing material from a company from California to Brno, so I know what I am talking about. However, without the transfer of a person who possesses the know-how to apply nickel brazing, it was almost impossible.<\/p>\n<p><a href=\"https:\/\/intelligent-kalam.80-240-27-133.plesk.page\/wp-content\/uploads\/2025\/06\/379-obrazek19.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-9596\" src=\"https:\/\/intelligent-kalam.80-240-27-133.plesk.page\/wp-content\/uploads\/2025\/06\/379-obrazek19-225x300.jpg\" alt=\"\" width=\"225\" height=\"300\" srcset=\"https:\/\/intelligent-kalam.80-240-27-133.plesk.page\/wp-content\/uploads\/2025\/06\/379-obrazek19-225x300.jpg 225w, https:\/\/intelligent-kalam.80-240-27-133.plesk.page\/wp-content\/uploads\/2025\/06\/379-obrazek19-768x1024.jpg 768w, https:\/\/intelligent-kalam.80-240-27-133.plesk.page\/wp-content\/uploads\/2025\/06\/379-obrazek19.jpg 1386w\" sizes=\"auto, (max-width: 225px) 100vw, 225px\" \/><\/a><a href=\"https:\/\/intelligent-kalam.80-240-27-133.plesk.page\/wp-content\/uploads\/2025\/06\/379-obrazek21.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-9598\" src=\"https:\/\/intelligent-kalam.80-240-27-133.plesk.page\/wp-content\/uploads\/2025\/06\/379-obrazek21-300x208.png\" alt=\"\" width=\"433\" height=\"300\" srcset=\"https:\/\/intelligent-kalam.80-240-27-133.plesk.page\/wp-content\/uploads\/2025\/06\/379-obrazek21-300x208.png 300w, https:\/\/intelligent-kalam.80-240-27-133.plesk.page\/wp-content\/uploads\/2025\/06\/379-obrazek21.png 605w\" sizes=\"auto, (max-width: 433px) 100vw, 433px\" \/><\/a><\/p>\n<p><strong><em><u>Fig. 2<\/u><\/em><\/strong><em> \u2013 The golden treasure of the company, the holder of know-how<\/em><\/p>\n<p><strong><em><u>Fig\u00a0 3<\/u><\/em><\/strong><em> \u2013 Example of parts for brazing<\/em><\/p>\n<p>The brazing process itself is simple, but it has one problem.
