Welding simply refers to the process of melting two metals together. The two metals are placed in contact, and a filler material is added to the joint; this creates a weld bead. Because of the high melting point of the heat used, molten material is formed, and this is termed “weld pool.”

When the pool cools, it can be as strong as or even stronger than the parent metals Brazing is a method of joining two or more metals together with the use of filler and heat.

The filler metal usually has a lower melting point compared to the adjoining metal. Due to less heat used, it is less likely that contaminants will burn out, but in welding, the hear burns out the contaminants.

Welding and brazing are two types of practices that are used for joining different metal parts. These two strategies are also used to fix or join broken parts or to fill the gaps in metals and have the same use and outcome. They have different processes.

Welding is utilized for joining metal pieces as well as thermoplastics. Welding is a process where the base metal, as well as the filter metal, is melted, and each one forms a molten material or a weld pool. The weld pool solidifies to make a sturdy joint.

Unlike welding, the filler metal is melted in the brazing technique. Welding melts both the base and the filler metal. Brazing only melts the filler metal. In welding, high temperatures are necessary. In brazing, temperatures are lower.
