What is the significance of maintaining the correct electrode angle in welding?
✔✔It ensures proper penetration, minimizes spatter, and helps achieve a clean and consistent
weld bead.
What happens when you use the wrong filler material for a weld?
✔✔It can lead to poor bonding, reduced strength, and potentially cause the weld to fail under
stress.
What is the purpose of tacking during a welding process?
✔✔To hold the parts in place temporarily before completing the full weld, ensuring alignment
and preventing distortion.
How does a welder know when to stop a weld?
✔✔By monitoring the weld pool and observing the appearance of the bead, ensuring adequate
penetration and fusion before finishing.

, What effect does using too little heat during welding have on the final result?
✔✔It may cause insufficient fusion, leading to a weak joint with a risk of cracking or failure
under load.
What is the role of a "weld map" in complex welding jobs?
✔✔To track and plan the sequence and technique of welds, ensuring consistency, accuracy, and
effective heat distribution throughout the project.
Why might you choose flux-cored welding over traditional stick welding?
✔✔It allows for higher deposition rates and better control in outdoor conditions due to its self-
shielding capability.
What does the "heat-affected zone" (HAZ) refer to in welding?
✔✔The area of the base metal that has been altered by the heat from the welding process,
affecting its mechanical properties.
How do welders ensure their welds are visually appealing?
✔✔By controlling the speed, heat, and technique, and by using clean materials to prevent spatter
and irregular bead formation.
