The standard details the procedures such as preparing, cleaning and application of heat and the filler material. The guidelines are clearly discussed in the ASTM B828 installation standard. Regardless of the metal joining method used, proper steps must be followed for a consistently strong joints. The method is popular in automotive applications. Brazing is perfect for joining just about any metals together except magnesium and aluminum. However, other industries also utilize the metal joining method i.e., motor vehicle industry when doing engine repairs, plumbing industry when joining pipes together, arts and crafts industry, and jewelry industry, among many others.īrazing, on the other hand, is common in wetting and removing oxides from base materials to allow filler metal bond perfectly with metal parts. As mentioned above, soldering is a common metal and component joining method in the electronics industry used to join wires and electronic parts together (such as switch components). The soldering and brazing difference can also be explored in the applications of each method. In soldering, preheating isn’t mandatory. What’s more, the base metal must be heated when brazing. Generally, brazing is done at temperatures exceeding 450 degrees Celsius, while soldering is done at temperatures lower than 450 degrees Celsius. While both are metal joining methods where two or more metals are joined together by melting a filler metal into a joint, and both can join dissimilar and similar metals together, brazing requires more heat i.e., at temperatures nearing fusion temperatures when welding. Temperature DifferencesĪs mentioned above, soldering requires lower temperatures than brazing. What is the Difference Between Soldering and Brazing?įor in-depth information on how soldering is different from brazing, here’s what you should know. However, the heat should be less than the melting point of the metal in question. Brazing requires temperatures above 450 degrees Celsius. What’s more, brazing requires higher temperatures than soldering. The resulting bond is stronger than soldering when joining metals but may not be as strong as other metal joining methods like fusion welding. The method can join ceramics, glasses, plastics, and composite materials. Unlike soldering, brazing isn’t specifically reserved for joining metals together. The method involves heating and melting the filler metal, which binds metal pieces together. For instance, gold, copper, silver, and aluminum metals can be joined together by brazing. Like soldering, brazing can join dissimilar metals together. What is Brazing?īrazing is a metal joining method like soldering. The process is used to join wires and other components together. In regards to application, soldering is extremely common in electronics. However, safety concerns have resulted in other safe alternatives like tin alloys. Soldering utilizes solder, which is commonly made using tin alloy. A bond is formed when the solder (filler metal) solidifies and bonds joining two metals together. Soldering can also be differentiated from the fact that filler material melts at low temperatures resulting in little to no part distortion or heat damage on sensitive parts. What’s more, unlike other metal joining methods, soldering doesn’t need a fluxing agent. When compared to metal joining methods like brazing, soldering is considered a low-temperature method considering the filler material (solder) is heated at temperatures not exceeding 840 degrees Fahrenheit (450 degrees Celsius). The method uses filler material to join metals together. One unique characteristic about the method lies in the fact that it can join both similar and dissimilar metals together. Soldering can qualify as one of the most popular and oldest methods of joining metals together. The term soldering refers to a metal joining technique. Below are the definitions and main soldering vs Brazing differences to consider. Generally, the two metal joining methods differ depending on many factors ranging from the required temperature to the strength of resulting joints and how each method is used (application). To understand the difference between brazing and soldering, we must begin by defining the terms and then getting into more details that distinguish soldering from brazing in depth.
