Improves “wetting out” characteristics and heat transfer, which allows the filler metal to flow and not ball up.Removes oxides from metals to be joined (you will still need to clean your metals prior to application).It is imperative to use flux for the following reasons: Flux is used in extracting and joining metals and is crucial to promote melting of the filler metal. “ We need flux!”įlux is a chemical cleaning agent, flowing agent, or purifying agent. Now we know the difference between the applications, but we need something else to complete the job. ![]() Of course, always follow your procedure or spec sheet for the proper application for every job! This is sometimes the most desirable application, because it has a lower liquidus state compared to brazing. Since soldering has a lower processing temperature, the joint is not as strong, compared to the brazing application. If you are soldering any type of electronics, you will need to keep in mind that the temperature needs to stay below 842 degrees Fahrenheit so that your electronics don’t burn up. This makes the joint electrically strong and can withstand any electric currents running through. Soldering also involves a filler metal but turns to liquid below 842 degrees Fahrenheit (450 degrees Celsius). Did you ever wonder how your cookware was so durable? Probably not, but it’s still good to know! You may not know, but your cookware and utensils are also put together using this application. You would typically see this application being used in the automotive industry, for jet engines and in HVAC. Brazing applications are a mechanically strong joint. The American Welding Society (AWS) defines brazing as a process which involves a filler metal that turns to liquid above 842 degrees Fahrenheit (450 degrees Celsius). “What’s the difference between soldering and brazing?” Not to worry, we will help you choose what flux is right for you, but first you will know the difference between the applications. You’ve decided to make a repair you have your soldering gun or brazing torch ready to go, but it hits you! “I don’t have any flux!” ![]()
