What is the primary purpose of welding?
✔✔The primary purpose of welding is to join two pieces of metal together by melting the
materials and fusing them into a single piece.
What is the difference between arc welding and oxy-fuel welding?
✔✔Arc welding uses an electric arc to melt the base material, while oxy-fuel welding uses a
flame produced by burning a mixture of oxygen and fuel gases.
Why is it important to wear protective gear while welding?
✔✔Protective gear, such as a welding helmet, gloves, and flame-resistant clothing, helps to
protect the welder from heat, sparks, and harmful radiation.
What does the term “welding bead” refer to?
✔✔A welding bead refers to the deposit of molten metal created by the welding process that
cools to form a solid joint between the workpieces.

, What is the role of shielding gas in welding?
✔✔Shielding gas protects the weld pool from atmospheric contamination, such as oxygen and
nitrogen, which can weaken the weld.
How do you maintain a stable arc while welding?
✔✔Maintaining a stable arc involves keeping a consistent distance between the electrode and the
workpiece and ensuring proper amperage settings.
What is the purpose of a welding machine's amperage setting?
✔✔The amperage setting controls the heat produced during welding, which affects the
penetration and strength of the weld.
What safety precautions should be taken before starting a welding project?
✔✔Before starting, ensure proper ventilation, check that all equipment is functioning correctly,
wear the appropriate PPE, and inspect the work area for hazards.
What is the role of the electrode in welding?
✔✔The electrode serves as the filler material that melts to form the weld and also acts as the
source of the arc in arc welding.
