  7. What are the main differences between casting and welding? Casting involves pouring molten metal into a mold to get the desired shape, while welding is a process of joining two metal parts by melting them together.

  8. Explain the sand casting process with its advantages. Sand casting involves creating a mold from sand, pouring molten metal, and allowing it to solidify. It's cost-effective for complex shapes.

  9. What are the common welding defects and their remedies? Common defects include porosity, cracks, and undercuts. Remedies include proper electrode selection and welding techniques.

  10. Describe the working of TIG and MIG welding. TIG uses a tungsten electrode and is precise, while MIG uses a wire feed as electrode and is faster for larger welds.

  11. What are the various types of patterns used in casting? Patterns include single-piece, split, match-plate, and cope-and-drag patterns.

  12. How does investment casting differ from die casting? Investment casting uses wax patterns and ceramic molds; die casting uses reusable metal molds under high pressure.

  13. What is heat-affected zone (HAZ) in welding? It's the area around the weld that experiences thermal cycles, affecting material properties.

  14. Explain the principle of arc welding. Arc welding uses an electric arc between the electrode and workpiece to melt and join metals.

  15. What is riser and its purpose in casting? Risers feed molten metal to the casting to compensate for shrinkage during solidification.

  16. Name different types of welding joints. Common joints are butt, lap, corner, edge, and T-joint.

  17. What are allowances in casting and why are they important? Allowances compensate for shrinkage, machining, and distortion during casting.

  18. Explain ultrasonic welding and its applications. Uses high-frequency vibrations under pressure to join materials. Common in electronics and plastics.

  19. What is porosity in casting and how can it be minimized? Porosity is trapped gas or shrinkage voids. Minimized by proper gating and venting systems.

  20. Compare permanent mold casting and centrifugal casting. Permanent mold uses reusable molds; centrifugal casting uses spinning molds for cylindrical parts.

  21. What safety precautions are necessary during welding operations? Use PPE, ensure proper ventilation, and follow correct procedures to prevent burns, shocks, and fume inhalation.
