What is meant by the term "arc length" in FCAW?
✔✔Arc length refers to the distance between the welding wire and the workpiece; maintaining
the correct arc length is crucial for achieving a stable arc and quality welds.
What does the term "heat-affected zone" (HAZ) refer to in welding?
✔✔The heat-affected zone (HAZ) is the area of the base metal that has been altered by the heat
of the welding process, potentially affecting its mechanical properties.
What is the significance of "weld bead" in FCAW?
✔✔The weld bead is the visible line of weld metal deposited during the welding process; its
appearance can indicate the quality of the weld.
What does "overlap" mean in the context of FCAW?
✔✔Overlap refers to a defect where the weld metal flows over the base metal without fusing,
which can weaken the joint.

, How is "deposition rate" defined in FCAW?
✔✔The deposition rate is the amount of filler metal deposited per unit of time during the
welding process, influencing the efficiency of the weld.
What is the role of "shielding gas" in FCAW?
✔✔Shielding gas provides an additional layer of protection to the weld pool, preventing
contamination and ensuring a cleaner weld, especially in gas-shielded FCAW.
What does "porosity" indicate in a weld?
✔✔Porosity is the presence of tiny gas pockets trapped in the weld metal, which can
compromise the strength and integrity of the weld.
How does "wire feed speed" affect the welding process?
✔✔Wire feed speed affects the amount of filler metal being fed into the weld pool; incorrect
speeds can lead to issues like undercut or excessive spatter.
What does "penetration" mean in welding?
✔✔Penetration refers to the depth of the weld metal into the base material; adequate penetration
is essential for a strong joint.
