Preface

The training of welders requires a great deal of individualized instruction. Often classes are large and stretch the instructor's ability to devote enough attention to each student.

Welding instructors need instructional material that will reduce the amount of one-on-one time required for each student. This workbook provides students with reference material so that they will not need to approach the instructor on items already covered. Thus students can use the reference material for reinforcement of their skills.

The main purpose of this workbook is to present the student with a wide variety of joint types and in a variety of positions, using a selection of the more popular electrodes used today.

The workbook does not purport to replace the instructor; the instructor must always be the ultimate authority and reference for the student.

The angles and manipulations for the electrodes and torches will do the job properly. Should the instructor have other preferences, they would certainly supersede those presented here.

The hands-on Procedures are designed to aid the instructor, and to assist the student in learning the fundamentals of welding. They should also reduce the number of times the student will have to go to the instructor with questions.

The Procedures should also assist the student in learning to follow written instructions as well as to develop a sense of responsibility toward the job.

Most of the questions students may have are covered along with descriptive drawings. In most cases there is further descriptive and explanatory information in the corresponding lesson in the Welding Processes and Practices textbook. Each Procedure in the workbook has been conveniently cross-referenced to its exact Section, Lesson, and page number in the textbook. Lessons should first be studied in that text, then the workbook should be used as a guide while performing the task.

Following the precepts of vocational education, it is suggested that the Procedure sheets be used in conjunction with the instructor's lecture and demonstration as supportive material.
