- Types of metal
Qualities, specifications, applications and reactions to different fabricating processes of various types of metal, such as steel, aluminium, brass, copper and others.
- Quality standards
The national and international requirements, specifications and guidelines to ensure that products, services and processes are of good quality and fit for purpose.
- Perform test run
Perform tests putting a system, machine, tool or other equipment through a series of actions under actual operating conditions in order to assess its reliability and suitability to realise its tasks, and adjust settings accordingly.
- 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.
- 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.
- Remove processed workpiece
Remove individual workpieces after processing, from the manufacturing machine or the machine tool. In case of a conveyor belt this involves quick, continuous movement.
- Apply preliminary treatment to workpieces
Apply preparatory treatment, through mechanical or chemical processes, to the workpiece preceding the main operation.
Identify operating problems, decide what to do about it and report accordingly.
- Remove inadequate workpieces
Evaluate which deficient processed workpieces do not meet the set-up standard and should be removed and sort the waste according to regulations.
- 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.
- 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.
- 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.
- Ensure equipment availability
Ensure that the necessary equipment is provided, ready and available for use before start of procedures.
- Wear appropriate protective gear
Wear relevant and necessary protective gear, such as protective goggles or other eye protection, hard hats, safety gloves.
- 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.
