1. -- INTRODUCTION

TO THE LIQUID PENETRANT TRAINING PACKAGE

The training materials in this package are designed to provide a basic knowledge of the fundamentals of liquid penetrant testing. The training program should contain the following classroom hours to adequately present the information suggested in the ASNT publication SNT- TC..1A Recommended Practice t June

1975 Edition. Level I training will include lectures ~n all six lessons with an average of approximately one hour per lesson. Emphasis by the instructor should be given to lessons 1·4 which cover the basic types and applications of penetrants. Level I1training will include lectures on an six lessons with an average of approximately two hours per lesson. Emphasis by the instructor should be given to lessons 5-7 which cover inspection and discontinuity evaluation. If the training program is aimed at meeting the guidelines for Level I t the instructor can follow the lecture guide closely with very little elaboration or explanation. If the Level 11guidelines are to be met, the instructor should encourage additional outside reading and class discussions and should present personal information to elaborate on the lecture guide outline. Each program can be easily expanded and is limited only by the instructor·s experience and expertise. The materials in this course are formatted for use in a typical classroom training situation with an ideal class size of 5-25 students. The instructor will lecture on all lessons with the aid of the lecture guide transparencies provided. 11.

CONTENTS OF TRAINING PACKAGES It is not a requirement that the instructor selected to teach the course be a professional educator or an expert in the liquid penetrant method. However, the instructor should be familiar with all materials before attempting to teach the course. This course is designed to provide a maximum amount of learning with a minimum amount of preparation by the instructor. The following breakdown of the materials and their functions should be carefully studied.

1. STUDENT PACKAGE-Each package will contain the following: A. Student's Guide which will describe the course and provide a lesson outline. B. 1 Classroom Training Handbook which will serve as the major text for the training course (CT-6-2). C. 7 individual lecture guide packets which provide an outline of the fundamentals of the liquid penetrant instruction.

D. 1 packet of quizzes. A quiz will be furnished for each of the 7 lessons in the training course. 2. INSTRUCTOR'S PACKAGE-Each package will contain the following: A. Instructor's Guide which will provide instructions to the instructor in preparing for and istering this course.

SUGGESTED USE OF INSTRUCTOR LECTURE GUIDE TRANSPARENCIES 1. The transparencies can be used on any standard overhead projector. 2. The infonnation on the transparency is i:dentical to the student lecture guide contained in the student packet. The "Lecture Guide Transparencies" are intended to serve as memory joggers for the instructor and should not be used 8S a strict outline or script. A. The instructor should cover the overhead projector with a sheet of heavy paper and lower it under the transparency after each item is discussed. A special pen is enclosed for use as a pointer and for writing on the transparent sheet. B. The instructor should elaborate and relate personal infonnation whenever it is pertinent. C. Prior to the lecture the instructor may wish to record some additional information on the lecture guides. This could either be done directly on the transparencies or on the instructor's set of lecture guides. D. Students should be encouraged to follow along in their set of lecture guides and write in additional information when it is given. Discussions and questions should be encouraged as the instructor proceeds through the lessons . .

IV.

SUGGESTED USE OF CLASSROOM TRAINING HANDBOOK

1.

The Classroom Training Handbook is the major source of information for this liquid penetrant training course. Additional infonnation from the programmed instruction handbook is sometimes added to the lecture notes t and the instructor may wish to review this source. 2. Reading assignments should be given to the students to correlate with the instructor's lectures. The Clsssroom Training Handbook CT-6-2 follows the lessons in this training course in the following order. PT-Lesson

SUGGESTED USE OF QUIZ"AND KEYS 1. It is suggested ing materials ..

that the QUiz paCket be removed before the student is issued his/her package of train-

2. Quizzes can be given at the end of the lecture or at the beginnin.Q of the next lecture period. The number of QUizzes given at one time will depend on the number of lessons covered. Quizzes can be corrected in class and should be discussed about interpretation of Questions and so on.

briefly with the students. Don't fall into deep arguments

3. The quiz questions in this package are not intended for use in total certification of NDT personnel. They are simply teaching tools to aid the instructor in presenting the material. If examinations for certification are needed. it is suggested that the instructor obtain a copy of SNT- TC-1 A and follow this recommended practice (par. 8 SNT- TC-1 A). 4.

VI.

If the i1stnJctor so chooses. the Quiz results could be used to arrive at a percentage score that could be recorded on the student's certificate of completion along with the number of course hours and/or CEU credits.

SUGGESTED

USE OF LIQUID PENETRANT F1LMSTRIP (optional)

1. The firnstrip is professionally produced and win add depth and clarity to the instructor's presentation. 2.

Part 1 of the filmstrip should be shown prior to the lecture on lessons 1-4 of this training course.

3. Part 2 of the filmstrip should be shown prior to the lecture on lessons 5-7 of this training course. The filmstrip will serve as a process review and discuss typical indications" 4.

VII.

If the lectures have take~ place over an extended period of time the instructor may WIsh to show the entire filmstrip again at the end of the course for review and continuity" J

SUGGESTED USE OF PROGRAMMED

INSTRUCTION HANDBOOKS (optional)

1. The nstructor may wish to read PI-4-1 and PI-4-2 as a personal review of the liquid penetrant funSome .,formation in the lecture guides was taken from the programmed instruction handbooks. 3. As some students may learn more effectively from the programmed instruction approach, the instructor may wish to also assign reading from PI-4-1 and PI-4-2. 2.

DEMONSTRATION AND/OR LAB EXERCISES 1. It is highly recommended that the instructor make every effort to provide the student with some practicaJ experience in liquid penetrant testing. The depth of practical exercises will depend on the time, equipment and facilities available to the instructor. t

2.

At a minimum t the instructor demonstration purposes.

should bring a variety of spray can penetrants into the classroom for

3. The instructor should use whatever resources are available to collect sample parts that will represent a variety of discontinuities. 4. If time, equipment. and facilities are available, each student should be given as much hands-on experience as possible. Where practical, a variety of lab stations should be set up. each with a different penetrant process. The student should then be rotated through each station with as many resource people as poSSible available to help answer specific questions. Penetrant manufacturers may be helpful in supplying a variety of penetrant materiaJs.

5. Where the instructor finds that all students are from a specific type of industry (e.g .. aircraft. foundry, welding), the demonstrations and lab work should be designed accordingly.

CONTINUING EDUCATION

UNITS (CEU's)

ASNT strongly urges that CEU's be given to partiCipants using this NDT training program. A form must be filled out requesting CEU credit each time this course is given and must include speCific details regarding performance evaluation and hours. One CEU is typically given for each ten hours of par-

ticipation in an approved NDT training program. Additional information regarding CEUts can be found in the Redi-Reference issue of Materials Evaluation or by ing ASNT headquarters. For your convenience a request form is included in this instructorts guide.
