The report below summarises the findings of the examiner team following the recent examination/assessment series.  Tutors are required to take note of the recommendations made by the Lead Examiner to ensure that candidates are supported in achieving the best possible outcome in future assessments.




1.1 Candidates understood heat conduction as a property within different types of materials.

1.3 Some candidates did not read the question fully referring to hot rolling of a material.

1.4 Many candidates were unfamiliar with the annealing range temperature.

1.5 This is an area where candidates are not given the correct information with regards to the quenching of stainless steel.

1.6 Candidates showed a good understanding of the effects of cooling on steel.

1.7/1.8 Candidates show a good understanding of the grain structure found in welded joints.

1.9/1.10 Candidates show a basic understanding of dilution but do not always give sufficient detail for full marks.

1.11 Many candidates described the use of rubber gaskets as a form of protection with regards to galvanic corrosion.



2.1 Good understanding shown by candidates with regards to the mechanical properties of materials.

2.3 Candidates show a clear understanding of the effects on working materials in the cold state.


3.2 Candidates showed clear understanding of the methods used to regulate current when welding.

3.4 Candidates showed clear understanding of power factor correction in a welding circuit.

3.5 Candidates showed clear understanding of the basic function of electrical components.

3.6/3.8 Many candidates incorrectly described the electrical output characteristics of a power source.

3.9 Candidates show a clear understanding of the duty cycle of a power source.



4.2 Many candidates confused surface area and volume, using radius rather than diameter in the calculation.

4.3 Many candidates did not show an understanding of the term ‘mean diameter’ for calculation a developed length.

4.4 Candidates confuse calculating volume and weight and are unable to show all workings.

4.5 Some candidates have shown confusion between the calculation of surface area and lengths of welds.

4.7 Calculations regarding the use of trigonometry are something that requires attention in centres, confusion shown regarding the use of Sine, Cosine and Tangent.

4.8 Many candidates were able to calculating the circumference but did not take into account the number of welds required.



5.3 Candidates showed a clear understanding of distortion control methods used.

5.6 Candidates showed a clear understanding of residual stresses within a material.

5.8 Candidates showed a clear understanding of Non Destructive welding techniques which shows good coverage of this area of the syllabus.

5.11 Candidates showed a clear understanding of welding procedures used in fabrication and welding showing good coverage of this area of the syllabus.
