How Does Filler Metal Welding Work?

🔍 To understand the process of filler metal welding, we need to explore its fundamental steps. First, the base metals to be joined are prepared by cleaning and removing any contaminants. Then, a filler material, usually in the form of a wire or rod, is selected based on the specific application and metal composition. This filler material is melted using a welding power source, such as an electric arc or a flame, and added to the joint, creating a molten pool. As the weld cools, the filler material solidifies, forming a strong and continuous bond between the base metals.
