The production of PWL7101 is based on agglomerated flux produced by imported technical know-how and equipment of Swiss Olicon welding industry company (former product name is OP-122) and with refined materials, it can highly satisfy the steel welding requirements for oil gas pipelines.
PWL7101 is fluoride basic flux, basicity >1.8. It is gray and round grain, with grain size around 2.0-0.28mm. It can be operated with AC and DC. The wire shall be connected to positive pole when applying DC. It has steady arc, and the welding bead smooth and pleasing, nice weld formation, and easy in slag removing, as well with perfect deposit metal welding technological characteristics.
Applications with applicable wires (EM12K, EH14, EA2, EA3, S3MoTiB) mainly used in the welding of low carbon steel and some low alloy steel (like 16Mn, X65, X70, X75, 355) structure and the SAW welding of boiler pressure vesels, ships, bridges, oil transportation lines, etc. It works excellently for welding Oil or Gas pipe line also can be applied to offshore plateform & High Tensile bridges.
