Abstract
A wet welding electrode, for manual arc welding underwater, has a coating containing at least one oxidizing agent such as iron oxide, for neutralizing the embrittling effect of nascent hydrogen, and its core contains at least one constituent, e.g. aluminum oxide, aluminum and nitrogen, or copper, which results in the presence of hardening components in the weld deposit.
