What is the main difference between a weld bead and a welded joint?

• A. A weld bead is the assembly formed by two pieces
• B. A weld bead is the resulting deposit of molten filler metal
• C. A welded joint refers to the power source used
• D. A welded joint indicates the area affected by heat

Answer: (B)

A weld bead is indeed defined as the resulting deposit of molten filler metal that is created during the welding process. This occurs when the welder applies heat, which melts the filler material and base metal, allowing them to fuse together as the molten substance cools and solidifies. The weld bead is essentially what is left behind after the welding process, representing the physical manifestation of the welding work. In contrast to the weld bead, a welded joint refers to the connection between two pieces of material that have been joined together through the welding process. This term encompasses the overall assembly formed by the structural combination of parts. Other options speak to different aspects of welding. For instance, one touches on the power source used in welding, which is separate from the physical characteristics of weld beads and joints. Another option mentions the area affected by heat, which relates to the heat-affected zone rather than the weld bead itself. Understanding these definitions allows for a clearer distinction between the components and processes involved in welding.
