Wet welding is a technique used to join metal parts underwater. It involves using a special welding rod that can create a strong bond even in the presence of water. This method is often employed in marine construction and repair, such as fixing pipelines or underwater structures. The process requires skilled welders who can manage the challenges of working in a wet environment. Wet welding is typically performed using arc welding methods, which generate heat to melt the metal and create a solid connection. This technique is essential for maintaining underwater infrastructure and ensuring its durability.
