Tubular electrode for wet underwater welding of steels

摘要

Tubular electrode for welding underwater wet steel comprises the present invention patent to an electrode specially developed to be used in soldering where the electric arc is in direct contact with the water, being coupled to the cable of a welding machine exactly me SMA as the conventional coated electrodes (with soul sound)Formed by a tube of carbon steel (1) with internal flow (2) and the outer covering (3). The components of the external coating (3) and the internal flow (2) developed in order to reduce the levels of oxygen and hydrogen, and the porosity of the underwater wet welding.
