Underwater welders make anywhere from $100,000 to $200,000 per year, according to the American Welding Society. Pay rates vary based on diving environment, work availability and other factors.
The amount of pay offered to an underwater welder is closely linked to the welder's expertise. Underwater welders with a lot of experience command higher rates of pay because they are able to work faster and more efficiently than novice underwater welders.
The salary for an underwater welder also varies based on the location of the job. Some areas have a higher cost of living than others, making it necessary for employers to offer higher salaries. The union in one area may also demand higher wages than the union in another area. Larger companies typically have more money available to pay underwater welders, so working for a large company often results in higher wages.
