NDT3452 VISUAL INSPECTION COURSE PROCEDURE


NDT 3452 VISUAL INSPECTION

3 Credit Hours

Student Level:

This course is open to students on the college level in either the freshman or sophomore year and to high school vocational students.

Catalog Description:

NDT 3452 - Visual Inspection (Inspection Practices) (3 hrs.)

This course is devised to introduce the student to forms of discontinuities in the manufacturing and service life of a part. Provide students with an understanding of how and why a specific nondestructive testing method is chosen. To acquaint students with visual inspection techniques, and their correct use. This course is designed to meet certain Nondestructive Testing Level II certification requirements.

Course Classification:

Lecture

Prerequisites:

None

Controlling Purpose:

This course is devised to introduce the student to the forms of discontinuities formed in the manufacturing and service life of a part. Provide students with an understanding of how and why a specific Nondestructive Testing method is chosen and to acquaint students with visual inspection techniques, and their proper use.

Learner Outcomes:

Upon completion of the course, the student will be able to:

1. List and define defects that occur in manufacturing.

2. List and define defects that occur in service.

3. Demonstrate the appropriate NDT method to perform an inspection.

4. Show proficient use of visual inspection instruments.

5. State the safety requirements associated with visual inspections

Unit Outcomes for Criterion Based Evaluation:

The following outline defines the minimum core content not including the final examination period. Instructors may add other material as time allows.

UNIT 1: PRIMARY PROCESSING-METAL FORMING, METALS PROCESSING, CASTING

Outcomes: Upon completion of this unit, the student will be able to successfully explain how metals are formed and how they are primary processed.

  • List and describe three materials types/properties in order from ferrow-magnetic to diamagnetic.
  • State three steps aluminum makes as it is transformed into a finished product.
  • List and describe the materials and processes when making carbon steel.
  • List and describe furnaces used in steel production.

UNIT 2: SECONDARY PROCESSING-HEAT TREATING, PLATING, MACHINING, ROLLING, AND FORGING

Outcomes: Upon completion of this unit, the student will be able to successfully summarize the secondary processes.

  • List and describe the effects of heat-treating and age hardening on aluminum materials.
  • List and describe the materials properties that are imparted to parts during various forms of heat-treating.
  • Understand the reason why coatings are applied to materials such as plating, anodizing, and painting.
  • List and describe the defects generated in the heat-treating and coating processes.
  • List and describe the results of the rolling process on grain structure.
  • List and describe the defects generated in the rolling process.
  • Describe the chipping process as it pertains to sawing, drilling, and machining.
  • Describe three types of equipment used in the machining or materials removing process.
  • Explain the uses of CNC equipment in the cutting and machining process.
  • List and describe defects that occur during the machining and cutting process.
  • Describe the forging process and defects that occur in the process.

UNIT 3: IN-SERVICE DISCONTINUITIES

Outcomes: Upon completion of this unit, the student will be able to successfully explain service discontinuities.

  • Explain the origins of service discontinuities.
  • Given five parts of various material properties, list and describe the type of in-service discontinuities would be produced during service life.
  • Given two in-service conditions, choose the one most likely to produce failure in the component.
  • Given four parts, choose the most appropriate method of inspection for in-service defects.

UNIT 4: JOINING PROCESSES-WELDING, BRAZING, SOLDERING

Outcomes: Upon completion of this unit, the students will be able to successfully list and describe the processes and uses of welding, brazing and soldering

  • Develop a chart listing the common welding processes and defects that occur in application of each.
  • Given two materials, select the process most likely used to join the two materials.
  • Explain the SMAW welding process.
  • Explain the GMAW welding process.
  • Explain the TIG welding process.
  • Perform visual inspections of welds to D1.1 code requirements.

UNIT 5: DIMENSIONAL INSPECTION INTRODUCTION

Outcomes: Upon completion of this unit, the students will be able to successfully state the particular equipment needed to measure dimensional tolerances.

  • List the uses of eight common dimensional measuring tools on parts used in industry.
  • Describe the advantages of computerized measuring equipment when inspecting a part.
  • Describe the visual and lighting conditions needed when performing visual inspection with measuring instruments.

UNIT 6: APPLICATIONS OF VISUAL INSPECTION EQUIPMENT

Outcomes: Upon completion of this unit, the students will be able to successfully apply knowledge of measuring equipment.

  • Demonstrate use of a CMM machine to measure components common to industry.
  • Demonstrate the ability to set-up and tear down a CMM measuring machine.
  • Using the CMM produce a report of measurements taken. Report will show any deviation from tolerances by +/-0.0001 inch or less.
  • Demonstrate the use of weld inspection gauges by successfully measuring material preparation, fillet and butt welds before and after welding.
  • Demonstrate the use of fiberscope by identifying three known areas within a part.
  • List and describe techniques for performing successful visual inspection as it pertains to lightning, reflectivity, angle of viewing, etc.
  • Explain the need for testing inspector’s eyes for visual acuity and color blindness.

Textbook:

Contact Bookstore for current textbook.

Attendance Policy:

Students should adhere to the attendance policy outlined by the instructor in the course syllabus.

Grading Policy:

The grading policy will be outlined by the instructor in the course syllabus.

Maximum class size:

Based on classroom occupancy.

Course Time Frame:

The U.S. Department of Education, Higher Learning Commission and the Kansas Board of Regents define credit hour and have specific regulations that the college must follow when developing, teaching and assessing the educational aspects of the college.  A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally-established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out-of-class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time.  The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face-to-face format.
