ALTAIR has been working in application of PAUT on materials since 2008

We are among the first few companies to have introduced PAUT in Singapore. Over the last 10 over years ASTC has grown in its capabilities and applications ranging from materials (CS, SS, DSS & Dissimilar Welds) and thickness (3mm to 180mm). We have inspected for Boiler Tubes (small Diameter Piping), Process Piping, Upstream piping welds and pressure vessels. We have also worked with complex shape materials like nozzles, valves, blow out preventors, shafts, R155 shells, bolts, flange etc.

Using the state of art technology, we develop our inspection model to deliver superior examination results. Our inspection development starts with simulation of material using a software for parameter selection and manufacturing of block with reflectors and applying these parameters for positive confirmation of techniques ability to detect and size. We have our own facility to manufacture especially designed scanner to reduce human error and achieve repeatable result. Because of our technically strong & creative approach, we are often our customer’s preferred choice especially in difficult to inspect materials.

For exotic materials (SS, DSS, Dissimilar Weld), we inspect welds based on transmit receive longitudinal wave technique (TRL). The grain size of welds often creates noisy signal which make inspection and analysis difficult and confusing. The new technique has revolutionized the examination of exotic material which was otherwise majorly RT dependent or modified UT limited to thicker materials or materials where RT was impossible.

We strive to be different with our creative thinking and ability to propose customized inspection solutions.
