Underwater Welding... How does Underwater Welding Work: Wet Welding Underwater dry welding may theoretically use any welding type that surface welders use. Underwater wet welding primarily uses shielded metal arc welding (SMAW). The welder works completely surrounded by water – including their electrode. Under the Microscope: How Electrons Affect the Process How does underwater welding work up close? First, you should understand what’s happening with the electrode at the molecular level. The hea
