SAW Flux


The production of PWL8101 Special is based on agglomerated flux produced by imported technical know-how and equipment of Swiss Olicon welding industry company (former product name is OP-143)

PWL8101 Special is a calcium-silicon type neutral Flux, alkalinity around 1.0. 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, nice weld formation, and easy in slag removing, as well with perfect deposit metal welding mechanical properties. It suits various welding conditions, with short sllags and no flow appearances.

Applications: Accompanying suitable wires (EL8 & EM12K) mainly used in the welding of normal low carbon steel (like X60, 235 etc.) structure and the SAW of boiler pressure vessels, ships, pipe line etc. Its deposit metal owns perfect impact toughness. It suits the SAW with multiple.
