Question:
Which of the following welding processes does not utilize a consumable electrode?
Which of the following welding processes does not utilize a consumable electrode?
Show Hint
In arc welding, if the electrode also provides filler metal, it is consumable. Advanced processes like electron beam or laser welding do not use consumable electrodes.
Updated On: Aug 23, 2025
- Plasma arc welding
- Gas metal arc welding
- Shielded metal arc welding
- Electron beam welding

The Correct Option is D
Solution and Explanation
Step 1: Recall types of electrodes.
- Consumable electrodes supply filler material along with arc heating.
- Non-consumable electrodes provide only heat, not filler metal. Step 2: Check each option.
- Plasma arc welding: Can use both consumable and non-consumable electrodes, but most industrial cases use non-consumable tungsten electrodes.
- Gas metal arc welding: Always uses a consumable electrode (filler wire).
- Shielded metal arc welding: Uses a consumable electrode coated with flux.
- Electron beam welding: Uses a high-velocity electron beam as the heat source, with no consumable electrode involved. Step 3: Conclude.
Thus, the process that does not utilize a consumable electrode is electron beam welding. \[ \boxed{\text{Correct Answer = (D)}} \]
