TS306 special waterproof welding, production technology, the introduction of Mitsubishi Corporation of Japan, import to avoid the gouache, the use of nickel-iron alloy for the welding of the core, double applicator layer of waterproof, anti-gas welding. Outer layer coated with slagging agents and water repellent is highly closed to ensure the quality of welding metal melting wailing: the inner layer is coated with alloy agent and oxygen scavenger in order to ensure arc stability and weld plastic and metal components. The air electrode can be used with water or underwater structural steel and cast iron pipe for all position welding. Is an ideal waterproof welding, the electrode can be AC ??and DC, but DC better.
