Short Test 1 Practice Flashcards

Flashcards covering safety, fabrication stages, metalworking techniques, and pipe fitting concepts from Short Test 1.

List three [3] safety precautions when lifting equipment?

1. Use correct lifting technique (bend knees, straight back).

2. Know your lifting capacity.

3. Clear paths and ensure a stable load.

List five [5] principles for the production of fabricated components and structures operational stages.

1. Operational stages.

2. Component forming and shaping.

3. Fitting and sub-assembly.

4. Primary and final welding/joining.

5. Quality inspection and finishing.

List three [3] advantages of air bending.

1. Versatility (single tool for many angles).

2. less tool wear.

3. Lower tonnage required.

Describe the difference between 'hollowing' and 'raising' in metalwork.

Hollowing - hammering sheet metal from the inside.

Raising - hammering sheet metal from the outside

When using a hammer or a mallet, describe the differences between:

1. A solid blow: A solid, direct impact used for driving force.

2. An elastic blow: A glancing or springy blow that utilizes rebound.

3. A floating blow: A light, controlled blow without heavy force, used for careful finishing.

List two [2] methods of wiring the edge of a curved surface.

1. Machine wiring.

2. Hand wiring.

List at least [4] ways of connecting the members in structural steelwork.

1. Welding.

2. Bolting.

3. Riveting.

4. Using cleats and plates.

Why are web stiffeners required in some structural components?

Web stiffeners prevent localized web buckling under concentrated loads.

State four [4] methods of taking measurement for pipe work or bending.

1. Center-to-center measurement.

2. End-to-end measurement.

3. Face-to-face measurement.

4. Template-based measurement.

List at least four [4] important factors to be considered in pipe fitting.

1. Material compatibility.

2. Correct pipe size and schedule.

3. Joint types (e.g., flanged, welded).

4. Thermal expansion.

List two [2] main disadvantages of copper pipe.

1. Higher cost compared to steel or plastic.

2. Susceptibility to corrosion in specific acid environments.

State three [3] factors that determine the precision position of the neutral line inside the bend.

1. The degree of the bend angle.

2. The ratio of bend radius to pipe diameter.

3. The material properties (ductility).
