A deck which is completely exposed to the weather from above and from at least two sides, (SOLAS).

Weather forecasting is the application of science and technology to predict the conditions of the atmosphere for a given location and time.

A weather station is a facility, either on land or sea, with instruments and equipment for measuring atmospheric conditions to provide information for weather forecasts and to study the weather and climate.

An instrument used for showing the direction of the wind, also known as wind vane or weathercock.

A weatherproof service drop entry point where overhead power or telephone wires enter a building, or where wires transition between overhead and underground cables.

Weathertight means that in any sea conditions water will not penetrate into the ship, (ICLL).

A door fitted in a structure above the freeboard deck. It must be of adequate strength and able to maintain the watertight integrity of the structure.

A flat plate with a flanged or stiffened edge.

A deep-section built-up frame which provides additional strength to the structure.

A method that can be used to present information or conduct a meeting via an online link with participants that are unable to attend a face to face meeting.

Weight is the force exerted on an object by gravity.

A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level.

The most common type of discontinuities are: cracks, incomplete fusion, slag inclusions, porosity, undercut. Imperfections of welding connections can be isolated or clustered.

A preferential corrosion of the weld deposit due to an electrolytic action between the weld metal and base metal.

The capacity of a material to be welded under the imposed fabrication conditions into a specific, suitably designed structure and to perform satisfactorily in the intended service.

One who performs a manual or semiautomatic welding operation.

A written certification that a welder has produced welds meeting a prescribed standard of the performance.

To ensure that a welder possesses the necessary skils to produce a sound weld he must complete a test piece which is representative of conditions that will be encountered during production welding.

A joining process that produces coalescence of materials by heating them to the welding temperature, with or without application of pressure or by the application of pressure alone, and with or without the use of filler metal.

The equipment used to perform the welding operation. For example: spot welding machine, arc welding machine, and seam welding machine.
