Efficiency
Determination is designed to assist learners in determining the
proper joint efficiency value based on factors including joint category,
joint type, service restrictions. For Authorized Inspectors (AIs) and
Authorized Inspector Supervisors (AISs), the principal responsibilities are
to understandi ASME Code rules and to verify compliance during
construction of pressure vessels.
Learning
