👉 Brazing is a process of heating metal to a high temperature and then cooling it slowly. This process is used in welding, where the metal is heated to a certain temperature and then cooled quickly so that it can be fused together. Bashing is also called brazing, but there are some differences between them. In brazing, the metal is heated at a very high temperature (around 5000°C) and then cooled slowly in an enclosed chamber or on a hot wire.
