The following is a brief survey of ultrasonic (UT) NDT activity in Canada. Generally equipment and techniques are the same no matter where ultrasonics is done. Therefore this report will address only historical aspects of industrial UT in Canada and some of the regional projects and programmes.
Development of commercial nuclear power in the mid 1960's was probably the single most important factor leading to the advancement of ultrasonics in Canadian NDT. Demands for public safety and the rapid expansion of a new industry provided the needed impetus for the development of NDT in general. At that time Canada had a population of only 18 million people, few of which were knowledgable in UT. As with previous economic booms, Canada looked outside its borders to find the talent it needed. Thousands of skilled people, mostly European, immigrated to Canada. These people included engineers and NDT technicians with a better understanding of ultrasonics and its capabilities. In the begining the only code available in North America to address the needs of the pressure components in the nuclear industry was ASME. The first nuclear boilers in Canada were built to ASME Section VIII (for high pressure boilers). By the early 1970's changes to the ultrasonic requirements for nuclear work reflected the improved understanding of the method. This meant better techniques had to be developed. Experience brought from Europe, particularly in ultrasonic weld inspection, provided not only the needed inspection techniques but also the much needed source of training. Today Europe is no longer the sole source of ultrasonic experts, their Canadian students have learned well.
Central certification of NDT in the 1960's was very timely. Around the same time as the nuclear industry began to grow the MegaProjects began. Oil and gas exploration in the Arctic and northern Alberta meant thousands of kilometres of pipeline construction. Discovery of heavy oil in the Athabaska Tar Sands provided work for thousands of people in both the building of the refinery facilities and their operations. The controversial Baie James (James Bay) Hydroelectric project in northern Québec began in the 1970's and it too employed thousands of people.
Nuclear industry has now fallen out of favour and the poor global economy has meant the decline of the MegaProjects. However, the foundation that these projects provided to ultrasonics in Canada cannot be denied. In the period from about 1965 to 1985 improvements in UT instrumentation and technician competence raised the level of industry confidence in UT in Canada to such a level that areas of inspection that were previously the sole domain of radiography are now being replaced by UT.
