Q1. The diagram shown in fig 1 is a welding process.

• a. Name the type of welding and explain how the process is carried out.

  • The type of welding shown is Gas Metal Arc Welding (GMAW), commonly known as MIG welding.
  • Explanation: The process involves creating an electric arc between a continuously fed consumable wire electrode and the workpiece. This arc melts the wire and the base metal, forming a weld pool. A shielding gas, supplied from a cylinder, flows around the arc and weld pool to protect them from atmospheric contamination (like oxygen and nitrogen), which would otherwise cause porosity and weaken the weld. The wire is fed automatically through the welding gun, and the welder guides the gun along the joint.

• b. Name three (3) materials that can be welded using this method.

  • Three materials that can be welded using MIG welding are:
    • Mild Steel
    • Stainless Steel
    • Aluminum

• c. State three (3 (advantages of this type of welding process.

  • Three advantages of MIG welding are:
    • High deposition rates, leading to faster welding speeds.
    • Good weld quality with minimal spatter and a smooth finish.
    • Relatively easy to learn and operate compared to some other welding processes.

• d. Name the parts labeled a - e.

  • a: Weld pool (or Molten metal / Weld bead)
  • b: Shielding gas cylinder
  • c: Wire spool (or Electrode wire spool)
  • d: Wire feeder (part of the welding machine that feeds the wire)
  • e: Workpiece (or Base metal)
