Ocean Welding involves welding on ships, platforms, and marine structures above water, often requiring offshore safety training. Underwater Welding specifically refers to welding performed beneath the water surface, requiring specialized diving and underwater welding certifications. While both roles involve welding in marine environments, underwater welding is a specialized subset focused on submerged work, whereas ocean welding covers a broader range of above-water marine welding tasks.
