    What type of shielding gas is used for GTAW?

    • Tri-Mix

    • 75/25 Argon/Co2

    • Argon

    • Nitrogen

    Correct Answer
    A. Argon
    Explanation
    Argon is the correct answer for the type of shielding gas used for GTAW (Gas Tungsten Arc Welding). Argon is commonly used as a shielding gas in GTAW because it provides good arc stability and excellent protection against atmospheric contamination. It helps to prevent oxidation and ensures a clean and high-quality weld.

    Which answer best explains the meaning of the following weld symbol:       - ProProfs

    Which answer best explains the meaning of the following weld symbol:      

    • .25 Spot Weld

    • .25 Fillet weld

    • .25 Weld corners only

    • None of the above

    Correct Answer
    A. .25 Fillet weld
    Explanation
    The correct answer is .25 Fillet weld. This weld symbol indicates that a fillet weld with a size of 0.25 inches is required. A fillet weld is a type of weld that joins two pieces of metal at an angle, typically a right angle. The size of the weld refers to the leg length of the fillet weld, which is the distance from the root of the weld to the toe. Therefore, the symbol ".25" represents a fillet weld with a leg length of 0.25 inches.

    Antisplatter spray is recommended when welding watertight.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Antisplatter spray is recommended when welding watertight because it helps to prevent spatter from sticking to the surface being welded. This can be especially important when welding watertight, as any spatter that sticks to the surface could compromise the integrity of the weld and potentially lead to leaks. By using antisplatter spray, welders can ensure a cleaner and more reliable weld, reducing the risk of water penetration and maintaining the watertightness of the welded joint.

    GMAW steel with Co2 gives a deeper penetrating weld than 75/25 argon/ Co2

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because GMAW (Gas Metal Arc Welding) with CO2 (Carbon Dioxide) as the shielding gas provides a deeper penetrating weld compared to using a 75/25 mixture of argon and CO2. CO2 has a higher heat input and a more reactive nature, which helps to increase the weld penetration. On the other hand, the 75/25 argon/CO2 mixture is commonly used for welding stainless steel or thin materials where a shallower weld penetration is desired.

    What common practice is used to keep warping stainless steel under control?

    • Spray outside with water.

    • Clamp the part to the table.

    • Use a hotter, faster bead when welding.

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    All of the above practices are commonly used to keep warping stainless steel under control. Spraying the outside with water helps to cool the metal and prevent excessive heat buildup, which can lead to warping. Clamping the part to the table ensures it remains stable and stationary during the welding process, reducing the chances of warping. Using a hotter, faster bead when welding can also help minimize heat input and prevent warping. Therefore, all of these practices can be effective in controlling warping in stainless steel.

    Sharpening tungsten electrodes against the grain is preferred over with the grain.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Sharpening tungsten electrodes against the grain is not preferred over with the grain. When sharpening tungsten electrodes, it is generally recommended to sharpen them with the grain. Sharpening against the grain can result in a less precise and less durable point, as well as increased risk of contamination. Sharpening with the grain helps to maintain the integrity of the electrode and ensures a sharper and more effective point for welding applications. Therefore, the correct answer is False.

    .5875 is closest to which fraction?

    • 9/16

    • 5/8

    • 3/4

    • 3/8

    Correct Answer
    A. 9/16
    Explanation
    To determine which fraction 5875 is closest to, we can compare it with each fraction given. 5875 is larger than 5/8 and 3/8, so these fractions can be ruled out. 5875 is closer to 9/16 than 3/4 because the numerator of 9/16 is closer to 5875 than the numerator of 3/4. Therefore, the closest fraction to 5875 is 9/16.
