Characteristics of XINYU Submerged Arc Welding Wire：
( 1 ) Low temperature impact performance is  intelligent，welding slag
stripping is good.
( 2 ) The welding wire has  high melting rate, high efficiency, less flux
consumption，unipolar, bipolar, AC DC power supply are common.
( 3 ) Belong to neutral flux，suitable for single and multi layer docking of
pressure vessel, shipbuilding, steel structure bridge, etc.
