About this previous year paper
Section A
Section A contains short and basic questions that test the fundamental concepts of welding technology. Students need to give brief definitions, short explanations, and basic facts related to welding processes, defects, gases, and design factors. The questions are direct and check basic theoretical knowledge of welding.
Example Questions from Section A:
What is deformation resistance welding?
What are the effects of gases in welding?
Define dilution.
Name any four weld defects.
What factors cause slag inclusion?
Give examples of adhesives and their characteristics.
Section B
Section B includes medium-length questions that require detailed explanations of welding processes, joint designs, and working principles. Students must explain welding methods with diagrams, describe process parameters, and discuss advantages and limitations. This section tests practical understanding and application of welding technology.
Example Questions from Section B:
Explain welding symbols with examples.
Describe the process of Needle Arc Micro Plasma Welding.
Explain the working of TIG welding with a sketch.
Explain how process parameters influence Laser Beam Welding.
Describe the principle of Electron Beam Welding (EBW).
Section C
Section C contains long and advanced questions that require detailed explanations, diagrams, and analysis. Students must discuss inspection methods, welding quality testing, advanced welding processes, and joint design selection. This section evaluates deeper knowledge and problem-solving skills.
Example Questions from Section C:
Explain different joint designs in adhesive bonding.
Explain Dye Penetrant Testing and inspection of welds.
Explain discontinuities in welds and their causes.
Describe working of Ultrasonic Welding with a sketch.
Explain methods of diffusion welding.
