This international coding standard is suitable for pressure vessels, pressure pipe work and other critical applications such as bridges and some structural steel work applications.
Our instructor will first of all discuss the welder's experience and personal aims and/or the company's objectives for that specific welder, so that all parties can fully understand and agree the levels that need to be attained.
These tests are carried out in accordance with welding standard ASME IX or BS EN 9606 and are usually subject to volumetric inspection such as radiography or ultrasonic examination.
Depending on particular weld configuration, each test can cover a range of welding variables e.g. material thickness and welding positions.
Welder coding certificates must be signed every 6 months by a suitably qualified person to confirm the welder is still producing welds of the required standard and are formally re-tested AT LEAST EVERY TWO YEARS.
Practical assessment with a highly qualified TWI (The Welding Institute) welding instructor.
Competence is assessed through observation and practical tasks.
