    Introduction:

    WD-SJ105 is a fluoro-alkali type sintering flux with an alkalinity of about 3.2. It has the appearance of gray-black spherical particles of 10-60 mesh (2.0-0.28mm). The flux has advantages as follows: has good moisture absorption resistance; high particle strength; small loose packing density; low flux consumption during welding. The maximum welding current of the flux in the welding process up to 1200A and has arc stability; the formation of short slag after welding; narrow gap de-slagging is easy; do not drip slag in welding small diameter cylinders; beautiful weld formation; pure deposited metal; low SiO2 content, reducing the transition of silicon; has a high low temperature impact toughness. The wire is connected to the positive electrode when DC welding. With the corresponding wire, multi-layer welding, double-sided single-pass welding, multi-wire welding and narrow gap submerged arc welding, etc., can be used to weld higher strength marine steel, pressure vessel steel, pipeline steel, marine platforms and fine grain structural steel for important welded products.

     

    Applications:

    It can be used for butt and fillet welds of ships, pressure vessels, storage tanks, steel structures, bridges, spiral welded pipes and other structures.
