THIS COURSE IS FOR FITTER 1st YEAR STUDENTS.
INTRODUCTION TRADE THEORY
The manual of trade theory consists of theoretical information for the 1st year (Vol I of II ) course of the Fitter Trade.
The contents are sequenced according to the practical exercise contained in NSQF LEVEL – 4 syllabus on Trade Practical. Attempt has been made to relate the theoretical aspects with the skill covered in each exercise to the extent possible. This correlation is maintained to help the trainees to develop the perceptional capabilities for performing the skills.
The trade theory has to be taught and learnt along with the corresponding exercise contained in the manual on trade practical. The indications about the corresponding practical exercises are given in every sheet of this manual.
It will be preferable to teach/learn trade theory connected to each exercise at least one class before performing the related skill in the shop floor. The trade theory is to be treated as an integrated part of each exercise.
The material is not for the purpose of self-learning and should be considered as supplementary to class room instruction.
TRADE PRACTICAL
The trade practical manual is intended to be used in practical workshop. It consists of a series of practical exercises to be completed by the trainees during the 1st
year (Vol I of II ) course of Fitter Trade supplemented
and supported by instructions / informations to assist in performing the exercises. These exercises are designed to ensure that all the skills in compliance with NSQF LEVEL – 4 syllabus are covered.
The manual is divided into four modules. The distribution of time for the practical in the four modules are given below:
- Module 1:-Safety 25 Hrs
- Module 2 :- Basic Fitting 275 Hrs
- Module 3:- Sheet Metal 150 Hrs
- Module 4:- Welding 100 Hrs
- Total:- 550 Hrs
The skill training in the shop floor is planned through a series of practical exercise centered around some practical object. However, there are few instances where the individual exercise does not from a part of project.
While developing the practical manual, a sincere effort was made to prepare each exercise which will be easy to understand and carry out even by below average traninee. However the development team accept that there is a scope for further improvement. NIMI looks forward to the suggestions from the experienced training faculty for improving the manual.
