Why Sonaspection

Technical experience from concept through manufacture

With over 40 years of experience in the field, we are the leading provider of flaw manufacture and implanting techniques.
Our team of experienced welders, engineers and technicians, are experts in their fields, ensuring we manufacture the most accurate flawed specimens on the market.
Each specimen is unique, containing purposely induced flaws that are accurately sized and positioned.
All specimens go through extensive quality control processes to ensure our flaws are of the highest quality.
We pride ourselves on providing excellent customer service from the initial contact.
Whatever the challenge, we work hard to find solutions to ensure we can support our clients with exactly what they need.

Working with Sonaspection allowed us to develop calibration blocks that accurately reflected our inspection requirements while covering a broad range of diameters and thicknesses and minimising the number of blocks required. The quality of manufacture and attention to detail ensured we received reliable, fit-for-purpose reference standards that continue to support our UT and PAUT capability development and technician training.
