NDT has come along way since 1868 when Englishman SH Saxby used the magnetic field of a compass to locate cracks in gun barrels which is one of the first magnetic testing methods recorded.
Ultrasonic testing was the last of the NDT techniques to be developed and was touted as an ‘industrial application after the sinking of the Titanic. In 1928, Russian Sergei Sokolov, proposed the transmission of ultrasound energy to pass through a solid material and detect irregularities.
Through to today with advanced techniques like Phased Array UT and Digital Radiography which have been transferred from the Medical Industry across to the NDT field.
At iTest we utilise all of these techniques to provide our customers with the latest and most up to date technologies available.
Our technicians, are certified and experienced for each technique.
In 1890, C.L. Coffin of Detroit was awarded the first U.S. patent for an arc welding process using a metal electrode. This was the first record of the metal melted from the electrode carried across the arc to deposit filler metal in the joint to make a weld.
Since this time, there have been major advancements in welding including the development of sophisticated welding machines, welding processes and consumables.
Our welding inspection and supervision personnel are familiar with all welding processes.
We prepare weld procedures and provide tuition to upskill operators to meet the necessary standards.
In-service inspection is carried out on pressure equipment and pressure piping.
This is a statutory regulation and requires periodical inspection of air receivers, autoclaves, boilers and pressure equipment.
Within the in-service inspection umbrella there is also the requirement of pre-commissioning and commissioning inspections.
Our inspectors are fully conversant with the requirements of AS/NZS3788, API 510 and API 570.
