Which metalworking process fuses two pieces by heating them until they bond together?

• A. Welding
• B. Die casting
• C. Forging
• D. Casting

Answer: (A)

Welding is the process that fuses two metal pieces by heating them until they bond together. The heat melts the edges so they flow and join as they cool, often with filler material to strengthen the joint. This creates a single, continuous piece along the joint. Die casting and casting involve melting metal and pouring it into a mold to form a single part rather than bonding two separate pieces. Forging uses heating and hammering to shape metal, typically deforming one piece rather than joining two pieces to become one.
