One who operates adaptive control, automatic, mechanized, or robotic welding equipment.

The detailed method and practice involved in producing a specific weld.

The order of making the welds in a weldment.

Distortion of weldments created by localized heating of the metal being joined together.

Space in the bottom of a ship to which bilge water drains so it may be pumped overboard. Any area on the deck exposed to the weather, where water may be entrapped.

Well drilling is the process of drilling a hole in the ground for the extraction of a natural resource such as ground water, brine, natural gas, or petroleum, for the injection of a fluid from surface to a subsurface reservoir or for subsurface formations evaluation or monitoring.

The condition of a well or reservoir defined by depth, temperature, shut-in pressure, flow rate, well fluid composition, etc (ABS).

A well intervention, or well work, is any operation carried out on an oil or gas well during, or at the end of, its productive life that alters the state of the well or well geometry, provides well diagnostics, or manages the production of the well.

A dynamically positioned (DP) ship-shaped offshore unit provided with equipment for well stimulation or maintenance (e.g. coil tubing).

Well logging, also known as borehole logging is the practice of making a detailed record (a well log) of the geologic formations penetrated by a borehole.

Worldwide there are more than 3000 subsea wells and, to increase the oil recovery from these wells, there is a demand for an efficient live well intervention service.

In the petroleum industry, a well test is the execution of a set of planned data acquisition activities.

Facilities installed on vessels or mobile offshore drilling units (MODUs) for the purpose of evaluating the quality and/or quantity of well fluid to determine whether the well should be completed for production or plugged and abandoned.

A wellhead is the component at the surface of an oil or gas well that provides the structural and pressure-containing interface for the drilling and production equipment.

The Western Interconnection is one of the two major alternating current (AC) wide area synchronous power grids in the continental U.S. power transmission grid.

The wet-bulb temperature is the temperature read by a thermometer covered in water-soaked cloth over which air is passed.

A wet cell battery has a liquid electrolyte.

A wet gas is any gas with a small amount of liquid present.

A device that remove pollutants from a furnace flue gas or from other gas streams.

Water vapor that includes water droplets is described as wet steam.
