Rationale:
It is very much important to impart basic welding skills to the Diploma Engineer as it is one of the most important manufacturing and salvaging technique.
They should be given training to use both arc welding equipment and Gas welding equipments. The safety precautions should be taught to them. Practice should be given to maintain the welding equipments. Students should know how to strike the arc, maintaining the arc, current selection for particular thickness and how to obtain various types of flames. They should be trained to do welding of different configurations.
Basic skills in lathe should be given to Diploma Engineers. Exposure to the working principles and various kinds of tools and methods of Turning, Drilling operations should be given.
