Spanning Canada and the United States, North America is home to a plethora of major industry players, including Exxon Mobil Corp, the world's second-largest publicly traded company after Royal Dutch Shell. The region's oil and natural gas industry is focused on developing oil sands, deepwater gulf prospects and increasingly profitable shale deposits stretching across the continent. One of the premier sweet spots for deepwater exploration, the Gulf of Mexico is the largest body of water indenting the U.S. continental coastline, and its subsea developments continue to spark both national and international interest.
Welding is a type of fabrication that is used to join metals or thermoplastics together by fusion. This is done by heating and melting part of the material and often adding a filler material which when cooled will form a strong bond. Pressure may also be used to weld, with or without the application of heat.<br/>There are different methods of welding used depending on the type of materials and desired end result, and Welders must be properly qualified for the type of welding work carried out.
