How does the choice of welding electrode affect the weld quality?
✔✔ The welding electrode type determines the arc stability, weld penetration, and overall
strength of the weld.
Why is it important to maintain proper electrode angle during welding?
✔✔ Maintaining the correct electrode angle ensures a stable arc, uniform weld bead, and reduces
the risk of defects.
What does "heat-affected zone" (HAZ) refer to in welding?
✔✔ The HAZ is the area surrounding the weld where the material's properties are altered due to
the heat from welding.
How does controlling the heat input in welding affect the final result?
, Why is preheating necessary for some materials before welding?
✔✔ Preheating reduces the risk of cracking by lowering the cooling rate and reducing thermal
stresses in the material.
What is the effect of weld metal cooling rate on the final weld properties?
✔✔ A fast cooling rate can lead to brittle welds, while a controlled cooling rate promotes
stronger, more ductile welds.
Why is it important to remove contaminants from the base metal before welding?
✔✔ Contaminants like oil, rust, or paint can lead to poor weld quality, defects, and weak bonds
in the final weld.
What is the significance of the "root pass" in multi-pass welding?
✔✔ The root pass is the first weld layer, which forms the foundation for subsequent weld layers
and ensures proper fusion.
How does the base metal thickness influence the welding process?
✔✔ Thicker base metals may require more heat, larger electrodes, or different welding
techniques to ensure proper penetration.
