Flashcards in SMAW process and Its applications Deck (4)
Electrical pressure is called _________ and measured in _______ the flow of electricity is called ______ measured in _________
Voltage, volts (V) and current, amperes (A)
How much heat is generated when the current crosses the arc from electrode to workpiece?
Anywhere from 5500°C to 6600 °C (9900°F to 11900 °C)
What does the coating on the electrode do?
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
