Specialist Welding Inspector (SPWI)



The Welding Greek Institute (WGI) offers an innovative and specialized short-term training program, recognised and accredited by major Welding Institutes and accepted by the international market, the Specialist Welding Inspector. The program will be implemented in blended learning (e-learning and in-class) or exclusively on e-learning. The instructors of the program are Phd Engineers, industry executives, Welding Inspectors and Engineers with extensive experience. The training program follows the guideline IAB-041r3-Latest Version for International Inspection Personnel – Basic Level without the Practical work module.

The total duration for Non-Qualified candidates, is 60 hours (If the program was performed in Class-Room). Under Distance Learning status, the time to perform both training modules could vary from 3 to 8 weeks, depending of the candidates’ commitment.


At the end of the training program, participants will acquire basic knowledge and skills regarding the following major issues:

  • Qualification of the welding procedures Specifications
  • Document Reviews of the method and range of qualification, specifications and laboratory testing shall be considered
  • Welding consumables
  • Identification of production and/or expiring dates
  • The storage and handling of welding consumables status
  • Identification and traceability
  • The identification of weld locations in construction
  • The identification of non-destructive testing procedures and personnel
  • Traceability of welder and welding operators to specific welds
  • Traceability of welding procedure specifications to specific welds
  • Inspection and testing during welding
  • Review of suitability and validity of welders’ and welding operators’ qualification certificates
  • Joint preparation overview (dimensions control, shape conditions)
  • Overview of suitability of working conditions for welding, including the environment
  • Visual inspection (for completeness of welding, weld dimensions, shape)
  • Review of non-destructive testing methods
  • Review of destructive testing methods
  • Quality Records completion of all activities required by specifications
  • Non-conformance and corrective actions after welding
  • Regarding to non-conformance and corrective actions, the necessary measures and actions (e.g. weld repairs, re-assessment of repaired welds, corrective actions) shall be considered


In the SPECIALIST WELDING INSPECTOR courses (Equivalent to the BASIC LEVEL of the International Classification for the International Welding Inspection Personnel), can only participate:

  • Technical Vocational Schools graduates
  • Diploma Holders from Higher Education Private College in relevant subject – minimum 3 years of study
  • Diploma Holders of Merchant Shipping Academies
  • Diploma Holders of Mechanical School
  • Diploma Holders from relevant Highest Educational Institution


At the end of each module takes place two hour written examination, with 40 questions / module. After passing the examination, candidates will be recognised as Qualified Specialist Welding Inspectors, absolutely fulfilling the requirements of the standards as stated in the purpose of education. Education Level is equivalent to the BASIC Inspection level.


After 3 years work experience in connection with the subject or an existing service, the Qualified Specialist Welding Inspectors will have the opportunity to be certified and participate in the Registry of the Welding Greek Institute for Certified Welding Inspectors with international recognition.


  • Cost of training: 1100 euro
  • Cost of exams: 200 euro / Written Exam
