What makes a weld visually appealing and structurally sound?
✔✔ A uniform bead profile, consistent width, proper penetration, and no visible defects like
cracks or spatter.
Why does the weld puddle shimmer like liquid metal in the arc's light?
✔✔ It’s the molten pool of metal, formed under intense heat, waiting to solidify and become part
of the joint.
What would happen if a weld joint were left unprepared, jagged, or dirty?
✔✔ The weld would likely have poor fusion, contamination, or weak points leading to failure.
What magical role does the shielding gas play during welding?
✔✔ It forms an invisible barrier, protecting the molten weld pool from atmospheric gases like
oxygen and nitrogen.

, Why does the heat-affected zone (HAZ) carry a hidden story of the welding process?
✔✔ It shows how heat has transformed the metal's microstructure, revealing details about
cooling rates and weld techniques.
What is the silent culprit behind weld cracks, waiting to strike?
✔✔ Rapid cooling, high residual stress, or improper welding technique.
Why is the "root pass" often called the foundation of a weld?
✔✔ It establishes the base strength and ensures the deepest penetration at the root of the joint.
If weld spatter could talk, what would it say about the welding process?
✔✔ “Too much heat, poor technique, or maybe the settings need a tweak!”
How does a weld inspector become a detective in the world of metals?
✔✔ By uncovering hidden clues like cracks, porosity, or undercut to ensure the weld meets the
required standards.
Why does slag sit proudly on the weld like a protective shield?
