lutowanie twarde vs lutowanie miękkie Explanation: by comparing English and Polish language description of soldering processes .. -------------------------------------------------- Note added at 1 hr (2019-10-10 09:42:21 GMT) -------------------------------------------------- •Difference between soldering and brazing Soldering involves joining of materials with a filler metal that melts below ~450 °C. It generally requires a relatively fine and uniform surface finish between the faying surfaces. The solder joints tend to be weaker due to the lower strength of the solder materials. Brazing utilizes filler materials with a melting temperature above ~450 °C. Surface finish tends to be less critical and the braze joints tend to be stronger. - https://en.wikipedia.org/wiki/Brazing -------- Zależnie od temperatury topnienia lutu rozróżnia się: lutowanie miękkie (poniżej 450 °C) lutowanie twarde (powyżej 450 °C) - https://pl.wikipedia.org/wiki/Lutowanie -------------------------------------------------- Note added at 2 hrs (2019-10-10 09:50:54 GMT) -------------------------------------------------- 17.

lutowanie twarde vs. lutowanie twarde Explanation: I believe these terms are synonymous. ccccccc Hard Soldering • Hard soldering is a general term for silver soldering and brazing . Hard Soldering • The term ‘ brazing ’ is derived from the fact that the filler material (spelter) is a brass alloy of copper and zinc and a typical spelter containing 40% copper and 60% zinc melts at about 850°C to produce a strong and malleable joint. This is very much higher than the temperatures required when soft-soldering. • Brazing is defined as a process of joining metals in which the molten filler material is drawn into the gap between the closely adjacent surfaces of the metals being joined by capillary attraction. http://weldinginst.yolasite.com/resources/19.2.1.pdf cccccccc brazing lutowanie twarde hard soldering lutowanie twarde https://www.memrise.com/course/488700/sowka-techniczne-2/6/ -------------------------------------------------- Note added at 2 hrs (2019-10-10 10:35:27 GMT) -------------------------------------------------- ccccccccccccccccccccc Brazing or hard soldering is the joining of metallic surfaces by an interposed alloy film. This type of soldering is used on metalwork to give a stronger joint than could be obtained by soft soldering. The surfaces to be brazed must be carefully cleaned, every trace of grease removed. As a cleaning agent, carbon tetrachloride is recommended Gasoline is not very suitable, as parts cleaned will retain a residual oil film. https://www.appropedia.org/Hard_soldering ccccccccccccccccccccccccc Brazing Involves High Temperatures Brazing involves a solder material that melts at a higher temperature compared to soft and hard soldering. Brazing is similar to hard soldering because the pieces of metal being bonded together are heated, but not melted, during the bonding process. Once you have the base metals heated, place solder material, called brazing filler metal, between the surfaces, It instantly melts. The molten filler material bonds the joint between the base metals through a process called capillary action. https://www.hunker.com/13414270/what-are-the-three-types-of-... cccccccccccccc Konkluzja: Można dodać brazing = wysokotemperaturowe lutowanie twarde |
