Course Name: Certificate in Fabrication
Course Credits: 0-2-0
The course involves identifying metals- tools; carrying out fitting and fabrication operations like measuring- marking out, welding & sheet metal work and inspecting of components in order to fit a component as per specifications.
Fabrication technology is the most important job skills for Mechanical Engineers. It is very essential technology in Industrial infrastructure development such as erection, commissioning of pipes, shipping, Power plants, steel plants, cement plants etc. This is pure workshop training and it gives the opportunity to the students, hands on experience on fabrication equipment, safety engineering, plant technologies etc.
1. Complying to the industry specifications, guidelines and safety standards during fabrication
2. Familiarization with the principles, materials, and tools required in the fabrication
3. Developing an end-to-end technical understanding
Students will able
1. To read & interpret technical parameters/documentation, plan work, identify necessary
processes, materials, and tools
2. To design different sheet metal working processes
