Underwater welding and cutting are specialized commercial diving activities used for marine repair, modification, removal and underwater construction work. Each operation requires careful planning because the work combines diving hazards with welding, cutting, electrical and structural risks.
Typical Applications
Applications may include underwater steel repair, removal of damaged steel components, cutting of piles or structural members, temporary repairs, installation support and other project-specific tasks.
Planning and Safety
Before work begins, the team should evaluate the underwater environment, structure, current, visibility, access, material condition and required equipment. A job-specific risk assessment, communication system, surface support and emergency arrangements are important parts of the diving plan.
Equipment and Documentation
Depending on the scope, operations may use surface-supplied diving equipment, underwater communication and CCTV, hydraulic tools, underwater welding or cutting equipment and suitable surface support. Work progress can be documented through diving logs, photographs, video and project reports.
