What challenges differentiate welding in offshore and onshore environments?

摘要

The types of material used is a big differentiator. It's more difficult to weld the harder offshore steels than it is to weld the traditional materials used in cross country pipeline. Offshore pipelines also have more environmental challenges that must be considered, including corrosion of salt water, tidal pressures and fatigue. The arc tends to be more erratic, harsh and difficult to control with the steels used in offshore pipeline welding.
