Efficiency Determination, is an online course designed to provide knowledge to the new construction inspector in determining proper joint efficiency value based on factors including category, joint type, service restrictions, and degree of radiography required for various joint categories and joint types. Also included are the principal responsibilities of the Authorized Inspector in understanding ASME Code rules and in verifying compliance during construction of pressure vessels.

Learning Outcomes
After completing this course, students will be able to:   

• Define the term joint efficiency.
• Explain the terms joint category and joint type.
• Describe the four joint categories.
• Describe the eight joint types and explain joint type limitations.
• Determine the types of welds required for Special Service condition vessels.
• Explain the meaning of required markings RT-1 through RT-4.
• Explain the terms radiographic examinations and ultrasonic examination.
• Determine when welded joints shall be examined radiographically, and to what degree they shall be examined.
• Determine the correct efficiency value (E) for a welded joint, based on joint type and degree of radiography.

Reference Materials
Although not required, each student may find it helpful to have the following materials (currently mandated edition):

• ASME Section VIII, Div. 1, Rules for Construction of Pressure Vessels

Note: ASME Code and Standards may be ordered through the ASME Web site.

Criteria for Successful Completion
As a minimum, for a National Board Certificate of Completion to be issued, students must:

• actively participate in all online course interactions
• respond to all knowledge check questions
