This question paper evaluates student knowledge in workshop technology, welding, casting, metal forming, heat treatment, machine tools, and manufacturing systems.
It is divided into three sections, covering definitions, medium-length answers, sketches, and long descriptive explanations.
SECTION – A (10 × 2 = 20 Marks)
This section contains short questions requiring brief explanations.
Topics include:
Components and operations of a shaper
Difference between shaper & planer
Production vs productivity
Types of production systems
Principle of oxy-acetylene welding
Types of gas flames and their uses
Annealing & normalizing of carbon steels
Electroplating & galvanizing
Tool steels and their classification
Ductile vs brittle fracture
This section checks basic manufacturing and material science concepts.
SECTION – B (5 × 10 = 50 Marks)
Students must attempt any five descriptive questions (many require neat sketches).
Topics include:
Shaper machine: components, operations, drive mechanisms
Oxy-acetylene welding: principles, flames, identification & applications
Annealing & normalizing with diagrams
Electroplating & galvanizing (process + sketches)
Tool steels, uses of copper alloys (brass/bronze)
Construction + working + applications of cupola furnace
Die casting: process with neat sketch
Ductile casting process & advantages
Slag inclusion and how to avoid it
Application of oxidizing, neutral & carburizing flame
This section tests process understanding, sketches, material behavior, and practical workshop knowledge.
SECTION – C (2 × 15 = 30 Marks)
Students must attempt any two long-answer questions.
Topics include:
Shaper Machine (Detailed)
Working principle
Construction with sketch
Operations
Limitations and applications
Production & Manufacturing
Role of materials and manufacturing in national growth
Types of production (job, batch, mass, continuous) with examples
Cupola Furnace & Related Concepts
Full working principle with labeled diagram
Advantages, limitations & casting applications
This section evaluates deep technical understanding, diagram-based explanation, and analytical skills.
