Where to start in Welding Inspection?

If you have little or no previous welding experience we advise that you attend the CSWIP Visual Welding Inspector as it will help you prepare for future attendance to the CSWIP Welding Inspector course. The CSWIP Welding Inspector course is designed for inspection engineers and supervisory staff.

If you require some practical welding knowledge to help improve your understanding of the inspection of welded products, please consider the CSWIP 3.0 Plus - Visual Welding Inspector with Practical Module course. It consists of 2 days of workshop related activities alongside the 2 days of welding inspection ahead of the CSWIP Visual Welding Inspector examination.

Does a CSWIP Welding Inspector qualification enable me to get on the TWI Diploma course?

Once you hold the CSWIP Welding Inspector you are eligible to take the entry exam for the Specialist Level.

How do I renew my CSWIP certificate?

After 5 years of holding CSWIP Certificate, please contact or go through CSWIP renewal to enquire for the application form as it can be done by documentary evidence.

After 10 years of holding CSWIP Certificate, please contact or go through CSWIP renewal to enquire for the application form as CSWIP will need to give you Approval to sit Recertification exam.

We strongly recommend refresher training prior to taking the 10-year recertification examination, however this is not mandatory. We have online (welding inspector and senior welding inspector) and classroom refreshers available.

Can I attend the CSWIP welding inspector with previous experience/qualifications in NDT?

Yes, it is possible if you also have a verified experience in visually inspecting welds.

I passed the visual welding inspector, can I go straight onto the next level (welding inspector) or do I require a certain element of experience?

You have to hold this level for a minimum of two years before moving to the next level.

Once I have attended the CSWIP welding inspector course, how long do I have to leave it before attending the CSWIP senior welding inspector?

You have to hold the CSWIP welding inspector level for a minimum of two years before moving to the next level.

What does a CSWIP welding inspection qualification allow me to do?

Detailed information is available in the CSWIP document.

What is involved in the additional radiographic interpretation part of the CSWIP senior welding inspector examination?

It involves the interpretation of at least 6 radiographs, densometry readings, sensitivity calculations and a 20 question multi-choice paper on radiography theory.

I would like to become a responsible welding coordinator, would having a CSWIP qualification help?

The welding technology knowledge gained from CSWIP welding inspection courses will help support your development of responsible welding coordinator competence.

How do I get a log book and stamp?

These are available from CSWIP – please contact them directly, they will be happy to help you.
