Typical Duties of Welding Inspectors
General
Welding inspectors are employed to assist with the quality control (QC) activities necessary to ensure that welded items meet specified requirements and are fit for their application.
For employers to have confidence in their work, welding inspectors need to to understand/interpret the various QC procedures and also have a sound knowledge of welding technology.
Visual inspection is one of the non-destructive examination (NDE) disciplines and for some applications may be the only form. For more demanding service conditions, visual inspection is usually followed by
one or more of the other non-destructive testing (NDT) techniques - surface crack detection and volumetric inspection of butt welds.
Application Standards/Codes usually specify (or refer to other standards) that give the acceptance criteria for weld inspection and may be very specific about the particular techniques to be used for surface crack detection and volumetric inspection; they do not usually give any guidance about basic requirements for
visual inspection.
CSWIP 3.1 Welding Inspector Course Guidance and basic requirements for visual inspection are given by: ISO 17637 (Non-destructive examination of fusion welds - visual Examination)
Basic requirements for visual inspection (to ISO 17637)
ISO 17637 provides the following:
Requirements for welding inspection personnel.
Recommendations about conditions suitable for visual examination.
Advice on the use of gauges/inspection aids that may be needed/helpful for inspection.
Guidance about information that may need to be in the inspection records.
Guidance about when inspection may be required during fabrication.
A summary of each of these topics is given in the following sections.
Welding inspection personnel
Before starting work on a particular contract, ISO 17637 states that welding inspectors should:
Be familiar with relevant standards, rules and specifications for the fabrication work to be undertaken.
Be informed about the welding procedure(s) to be used.
Have good vision – in accordance with EN 473 and checked every 12 months.
ISO 17637 does not give or make any recommendation about a formal qualification for visual inspection of welds. However, it has become industry practice for inspectors to have practical experience of welding inspection together with a recognised qualification in welding inspection – such as a CSWIP qualification.
Conditions for visual inspection
Illumination
ISO 17637 states that the minimum illumination shall be 350 lux but recommends a minimum of 500 lux (normal shop or office lighting).
Access
Access to the surface for direct inspection should enable the eye to be:
Within 600mm of the surface being inspected.
In a position to give a viewing angle of not less than 30°.
Aids to visual inspection
Where access for direct visual inspection is restricted, a mirrored boroscope or a fibre optic viewing system, may be used – usually by agreement between the contracting parties.
It may also be necessary to provide auxiliary lighting to give suitable contrast and relief effect between surface imperfections and the background. CSWIP 3.1 Welding Inspector Course covers Other items of equipment that may be appropriate to facilitate visual examination are:
Welding gauges (for checking bevel angles and weld profile, fillet sizing, measuring undercut depth).
Dedicated weld gap gauges and linear misalignment (hi-lo) gauges.
Straight edges and measuring tapes.
Magnifying lens (if a magnification lens is used it should be X2 to X5).
ISO 17637 shows a range of welding gauges together with details of what they can be used for and the precision of the measurements.
