Question 1

What is the mixture of melted electrode and melted parent metal created during welding called?

Answer 1

the weld deposit

This occurs when welding current flows through the electrode and across the arc.

Question 2

What is produced when the welding machine is turned on but no arc has been established?

Answer 2

open circuit voltage

This occurs before the arc is initiated.

Question 3

In shielded metal arc welding, what maintains the electric arc between the workpiece and the electrode?

Answer 3

covered electrode

This type of electrode is used to fuse metals.

Question 4

What is the approximate temperature range created by an electric arc during welding?

Answer 4

2500° and 3500°C (4532° and 6332°F)

This intense heat is essential for welding.

Question 5

The electrode coating in SMAW helps to _______.

Answer 5

all of the above

This includes keeping the arc stable, concentrated, and providing shielding gases.
