Question

select the correct definition for gmaw:

an arc welding process that uses an arc between a continuous filler metal electrode and the weld pool.
an arc welding process that uses a non-consumable electrode to produce the weld.
a manual arc welding process that uses a consumable electrode covered with flux
a process that uses fuel gases and oxygen to weld and cut metals.

Explanation:

Analyze GMAW acronym and process characteristics

GMAW stands for Gas Metal Arc Welding. It is an arc welding process that uses a continuously fed, consumable solid wire electrode (filler metal) and an externally supplied shielding gas.

Evaluate the given options

• Option 1: "An arc welding process that uses an arc between a continuous filler metal electrode and the weld pool." This matches the definition of GMAW (specifically highlighting the continuous filler metal electrode).
• Option 2: "An arc welding process that uses a non-consumable electrode to produce the weld." This describes GTAW (TIG welding).
• Option 3: "A manual arc welding process that uses a consumable electrode covered with flux." This describes SMAW (Stick welding).
• Option 4: "A process that uses fuel gases and oxygen to weld and cut metals." This describes Oxy-Fuel welding/cutting.

Select the correct option

Option 1 is the correct definition for GMAW.

Answer:

• (A) An arc welding process that uses an arc between a continuous filler metal electrode and the weld pool. (Correct answer)
• (B) An arc welding process that uses a non-consumable electrode to produce the weld.
• (C) A manual arc welding process that uses a consumable electrode covered with flux
• (D) A process that uses fuel gases and oxygen to weld and cut metals.
