SAW without flux
undefined
In visual inspection, undercut is best described as
A groove melted into the base metal adjacent to the weld toe - Explanation: Undercut is a longitudinal groove along the weld toe that reduces section thickness.
Excess metal at the weld toe
A cavity trapped inside the weld
A lack of fusion at the root
undefined
Which discontinuity is most likely caused by insufficient shielding gas or contaminated gas?
Lack of sidewall fusion
Porosity - Explanation: Entrapped gas from poor shielding, contamination, or moisture forms porosity.
Undercut
Slag inclusion
undefined
Which destructive test best evaluates weld metal ductility by bending the specimen without fracture?
Charpy V-notch impact test
Hardness survey
Guided bend test - Explanation: Bend tests assess ductility and soundness by bending to a specified angle without cracking.
Macroetch examination
undefined
For carbon-manganese steels, a typical factor that increases risk of cold cracking is
Slow cooling rate
High interpass temperature within WPS range
High restraint and high hardness HAZ - Explanation: High restraint, high hardness, and hydrogen promote cold cracking.
Low diffusible hydrogen consumables
undefined
Which parameter combination most increases heat input in arc welding?
Lower current, higher travel speed, higher voltage
Higher current, higher travel speed, lower voltage
Higher current, higher voltage, lower travel speed - Explanation: Heat input is proportional to V x I / travel speed.
Lower voltage, higher travel speed, lower current
undefined
Which NDT method is most suitable for detecting planar lack-of-fusion in thick plate welds?
Dye penetrant test
Ultrasonic Testing (UT) - Explanation: UT is sensitive to planar reflectors like lack-of-fusion, especially in thickness.
Hardness testing
Magnetic particle testing
undefined
True or False: DPI (PT) can reliably detect subsurface lack of fusion up to 3 mm below the surface.
True
False - Explanation: Penetrant testing only detects surface-breaking discontinuities.
undefined
Which joint preparation best helps avoid lack of sidewall fusion in thick plate GTAW/GMAW?
Square butt with no root face
Butt with zero gap and small angle
No prep; rely on high current only
Single-V with adequate groove angle and root face - Explanation: Proper groove angle allows access for fusion and penetration.
undefined
When calibrating an ultrasonic flaw detector, the purpose of using a IIW (V1) block is to
Determine film density for RT
Calibrate MPI yoke lift capacity
Measure ferrite number
Establish time base, velocity, and angle probe calibration - Explanation: IIW blocks provide known geometry for UT calibration.
undefined
True or False: In MT with AC yokes, subsurface indications several millimeters deep are readily detected.
False - Explanation: AC yokes are best for surface cracks; DC or HWDC provides better subsurface sensitivity.
True
undefined
Which acceptance criterion is typical for excessive weld reinforcement on a butt weld according to many fabrication codes?
No limit if smooth
Limited height, often around 3 mm subject to code and thickness - Explanation: Many codes limit reinforcement to control stress concentration and fit-up.
Must be flush ground in all cases
At least 6 mm
undefined
The most probable cause of linear slag inclusions in multi-pass SMAW welds is
Short arc length
Too high interpass temperature
Using low hydrogen electrodes
Inadequate slag removal between passes - Explanation: Entrapped slag lines often result from poor interpass cleaning or incorrect technique.
undefined
Which factor is most critical to prevent lamellar tearing in highly restrained T-joints?
Higher heat input only
Use of higher strength electrodes
Peening every pass
Use of Z-quality (through-thickness) steel and joint design change - Explanation: Reducing through-thickness strain and improving lamellar properties mitigates tearing.
undefined
In UT, the Distance Amplitude Correction (DAC) curve is used to
Correct angular error of the probe
Relate echo amplitude to reflector distance for sensitivity setting - Explanation: DAC allows comparison of indications to reference reflectors at various depths.
Calibrate RT film speed
Convert shear waves to longitudinal waves
undefined
True or False: Sensitization in austenitic stainless steel is chromium carbide precipitation at grain boundaries, reducing corrosion resistance.
True - Explanation: Carbide precipitation depletes chromium at boundaries, promoting intergranular corrosion.
False
undefined
When reviewing RT film, a typical indicator of inadequate IQI (penetrameter) sensitivity is
Visible density range of 2.5 to 3.5
Excessive backscatter symbol visibility
Inability to clearly resolve the required essential wire or hole - Explanation: IQI visibility demonstrates radiographic sensitivity per code.
Presence of geometric unsharpness Ug < permitted
undefined
True or False: FCAW self-shielded wires are suitable for all critical low hydrogen applications without special controls.
True
False - Explanation: Some self-shielded wires can be high hydrogen and require controls or may not meet low-hydrogen requirements.
undefined

Cheat Sheet

  1. Defect Classification Essentials -

    Familiarize yourself with ISO 6520-1 and AWS D1.1 standards to categorize defects like cracks, porosity, and undercut. Use the mnemonic "CUP" (Cracks, Undercuts, Porosity) to recall major planar and volumetric flaws instantly. This foundation is critical for tackling 3.1 independent practice answer key scenarios accurately.

  2. Radiographic Interpretation Techniques -

    Master the "step wedge" sensitivity concept to gauge film density variations per ASTM E1742 guidelines. Practice reading cswip 3.1 quiz questions on film quality indicators - differentiating between fog and scatter with side-by-side sample films. Clear interpretation skills boost confidence when scoring your cswip 3.1 practice test.

  3. Ultrasonic Testing Calibration -

    Learn the "2T" distance rule (two-way travel) from ASME Section V to verify sound path accuracy on reference blocks. Regularly check transducer delay and gain settings using standard calibration blocks endorsed by TWI. Proper calibration ensures you nail those cswip 3.1 independent practice answer key items on flaw sizing.

  4. Visual Inspection & Acceptance Criteria -

    Use the "Stop-Look-Measure" method from AWS QC1 to inspect weld profiles, checking for concavity, convexity, and toe cracks. Compare actual weld dimensions to code tables (e.g., BS EN ISO 5817) to determine pass/fail status quickly. This technique simplifies cswip 3.1 quiz questions on surface discontinuities.

  5. Code Familiarity & Exam Strategy -

    Build quick-reference sheets for key tables in EN IQ1 and AWS standards that appear most often in cswip 3.1 quiz questions. Time yourself on practice sets from IIW journals to simulate test conditions and improve pacing. A solid grasp of codes plus timed drills will elevate your performance in the 3.1 independent practice answer key review.
