In casting material of welding electrodes AP/span> is used in considerable quantities. High lose content ensures the correct burning of Electrodes, APis an inert material and it leaves practically nothing after incineration and provides a reduction atmosre due to the decomposition of organic material present in AP/span> thus it prevents oxidation. Resultant welding will be free from pinholes, cracks, etc. APhaving wonderful free flow ness helps in the smooth extrusion of Electrode without any cracks on its surface.
Slippery | Smooth extrusion |
Anionic poly-carbohydrate | Less smoke |
Free from Chlorides, Sulr & srous | Good quality of welding |
Free flowing powder | Easy mixed with flux |
Soluble & swell in cold water | Increase Green strength of electrodes |
