Brazing is a process used to join two metal pieces by heating them to a temperature where they melt slightly and flow together, while a filler metal is introduced to the joint to act as an adhesive. The process is widely used in manufacturing and repair industries and requires a source of heat and an appropriate atmosphere for the reaction to take place.
One crucial element in brazing is the gas used as an atmosphere during the process. The gas needs to be inert, non-reactive, and able to protect the joint from oxidation and contamination. One gas that has proven to be an excellent choice for brazing is oxygen.
Oxygen is a colorless, odorless, and tasteless gas that makes up about 21% of the earth’s atmosphere. It is highly reactive and supports combustion, making it an ideal choice for many industrial processes, including brazing. When used in brazing, oxygen creates an oxidizing atmosphere that removes oxides from the metal surfaces, allowing the filler metal to flow freely and bond to the joint.
Benefits of using an Oxygen in Brazing Process
One of the significant benefits of using oxygen in brazing is its ability to provide a strong and durable bond. Oxygen can create a higher heat intensity that allows for better penetration into the joint, resulting in a more secure bond. Additionally, the use of oxygen reduces the need for flux, which can be costly and time-consuming to apply and clean up.
Another advantage of using oxygen in brazing is its availability and affordability. Oxygen is readily available and can be easily stored, making it an attractive option for businesses of all sizes. Additionally, the cost of using oxygen is typically lower than using other gases, such as argon or nitrogen.
