- Realistic / Conventional
- Apply preliminary treatment to workpieces
Apply preparatory treatment, through mechanical or chemical processes, to the workpiece preceding the main operation.
- Apply spraying techniques
Apply the most optimal spraying techniques, such as a perpendicular spraying angle, maintenance at a consistent distance, trigger the spray gun gradually, overlap surface spots, and others.
- Rust proofing spray gun parts
The various parts of a spray gun designed to provide the surface of a workpiece with a durable rust proofing finishing coat, such as the grip, air-passage, air-hose connection, air valve assembly, air-control screw, fluid-hose connection, fluid nozzle, fluid needle valve, air nozzle, two-finger trigger, control screw for regulating flow of fluid and for removing needle valve, and others.
- Operate rust proofing spray gun
Operate a semi-automatic or handheld spray gun designed to provide the surface of a workpiece with a permanent, corrosion-protective finishing coat, safely and according to regulations.
- Spot metal imperfections
Observe and identify various kinds of imperfections in metal workpieces or finished products. Recognise the best fitted manner of fixing the problem, which could be caused by corrosion, rust, fractures, leaks, and other signs of wear.
- Recognise signs of corrosion
Recognise the symptoms of metal showing oxidation reactions with the environment resulting in rusting, copper pitting, stress cracking, and others, and estimate the rate of corrosion.
- Select spraying pressure
Select the optimal spraying pressure taking into account the kind of paint or primer being sprayed, the sprayed material, the spraying environment and other factors.
