What is underwater welding?
It is the process of welding in a submerged environment, typically in the ocean or freshwater bodies. The process involves using welding equipment and techniques that are specifically designed for underwater use. For this reason, the welder must have the proper training, certification, and experience to perform this type of work safely and efficiently.
