SMAW process and Its applications

Question 1

Electrical pressure is called _________ and measured in _______ the flow of electricity is called ______ measured in _________

Answer 1

Voltage, volts (V) and current, amperes (A)

Question 2

How much heat is generated when the current crosses the arc from electrode to workpiece?

Answer 2

Anywhere from 5500°C to 6600 °C (9900°F to 11900 °C)

Question 3

What does the coating on the electrode do?

Answer 3

Helps keep the arc stable and concentrated on a precise point on the weld. The chemicals in the electrode coating provide the required shielding required to protect the molten metal from contamination by the atmosphere

Question 4

What are the 2 types of welding power sources?

Answer 4

Direct current (DC) and Alternating current (AC)
