Answer

Brief Explanations:

  • Question 5: Shielded Metal Arc Welding (SMAW) involves melting both the electrode and the base metal to form a weld.
  • Question 6: The flux in the electrode coating shields the weld from impurities in the air (like oxygen and nitrogen) which could weaken the weld.
  • Question 7: The correct order is to first position the electrode (so it is in the right place relative to the base metal), then strike an arc (to start the welding process), and finally extinguish the arc (when the welding for that segment is done).
  • Question 8: Filler material in SMAW is used to fill gaps between the base metals and build up the weld bead to ensure a strong and proper - sized weld.
  • Question 9: The electrode holder's main function is to hold the electrode during welding, allowing the welder to manipulate it.
  • Question 10: Welding current in SMAW (and in general for electrical current in most electrical - related processes) is measured in Amperes. Volts measure electrical potential, Watts measure power, and Ohms measure electrical resistance.
