  1. What does the term 'interpass temperature' refer to in multi-pass welding?

    Answer: The maximum allowed temperature of the weld zone before depositing the next pass

    Interpass temperature is the maximum temperature the weld joint is allowed to reach between passes to control heat input and maintain material properties.

  2. Which shielding gas addition to argon increases arc heat and improves fusion on stainless steel in GTAW?

    Answer: Helium

    Adding helium to argon increases arc heat and energy, improving fusion and travel speed on stainless steel and non-ferrous metals in GTAW.

  3. In Friction Stir Welding (FSW), the weld is produced by:

    Answer: A rotating non-consumable pin tool that plasticizes and stirs material without melting it

    FSW uses a rotating tool to generate frictional heat that plasticizes (but does not melt) the base material, forging the joint in the solid state.

  4. When a Welding Procedure Specification (WPS) calls for DCEP polarity in SMAW, the current flows from:

    Answer: The workpiece to the power source negative terminal, then to the electrode

    In DCEP (DC Electrode Positive), electrons flow from the workpiece (negative) through the arc to the electrode (positive), concentrating heat at the electrode end.

  5. Which defect is most likely when welding a T-joint with insufficient root opening and travel speed that is too fast?

    Answer: Lack of fusion or incomplete joint penetration

    A tight root opening combined with excessive travel speed reduces heat input and prevents full fusion at the root, causing lack of fusion or incomplete penetration.

  6. What is the primary purpose of using a drag (trailing) shield in GTAW of titanium?

    Answer: To provide extended inert gas shielding over the hot weld and HAZ until they cool below 800°F

    Titanium oxidizes rapidly above 800°F, so a trailing shield continues inert gas coverage over the weld and HAZ until the metal cools enough to resist oxidation.

  7. Oxyfuel Gas Welding (OFW) uses which flame type to weld carbon steel to avoid carbon pickup?

    Answer: Neutral flame (balanced oxygen and acetylene)

    A neutral flame, with equal volumes of oxygen and acetylene, provides the correct heat without introducing excess carbon or oxidizing the weld metal.
