    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Practice maintaining a consistent arc length.
    • 💡Ensure correct PPE is worn at all times.
    • 💡Inspect welds for defects like slag inclusion.
    • 💡Practice maintaining a consistent arc length and travel speed.
    • 💡Always check equipment condition and settings before starting.
    • 💡Review welding symbols and joint preparation techniques.
    • 💡Practise striking the arc consistently.
    • 💡Maintain a steady travel speed.
    • 💡Check weld appearance for defects.
    • 💡Always double-check your measurements before cutting or drilling. A common mistake is misreading a calliper or ruler, leading to wasted material and lost marks.
    • 💡In practical assessments, demonstrate safe working practices consistently. Examiners look for correct use of PPE, tidy workspace, and proper tool handling throughout the task.
    • 💡When interpreting engineering drawings, pay attention to the title block and notes. These contain essential information about material, scale, and tolerances that affect your work.

    Common Mistakes

    Common errors to avoid in your coursework

    • Incorrect electrode angle or travel speed.
    • Poor arc striking technique.
    • Neglecting to clean the workpiece before welding.
    • Incorrect electrode angle or travel speed leading to poor weld profile.
    • Failure to clean base metal before welding.
    • Ignoring safety procedures such as fume extraction or fire precautions.
    • Incorrect electrode angle leading to poor weld.
    • Not cleaning the metal before welding.
    • Ignoring personal protective equipment (PPE).
    • Misconception: Engineering is only about heavy machinery and welding. Correction: Engineering technologies cover a wide range of skills, including precision measurement, drawing interpretation, and assembly of small components.
    • Misconception: Safety rules are optional if you're careful. Correction: Safety procedures are mandatory and based on legal requirements; ignoring them can lead to serious accidents and disqualification.
    • Misconception: Measuring by eye is good enough for engineering. Correction: Engineering requires precise measurements to within fractions of a millimetre; using the correct instrument and reading it accurately is critical.
