Alkalinity (low hydrogen type) electrode

Drug skin contains large amounts of alkaline slag material (marble, fluorite, etc.), and contains a certain amount of deoxidizer and alloying agent. AlkalineWelding Electrode depends mainly on the carbonate decomposition of CO2 for shielding gas (such as CaCO3), the arc column, an atmosphere of hydrogen partial pressure lower, and calcium fluoride in fluorite at high temperatures and hydrogen combine to form hydrogen fluoride (HF), reduce the amount of hydrogen in the weld, so the alkaline electrode is also known as a low hydrogen type electrode. Measured by glycerol per 100g diffusible hydrogen content in the deposited metal, alkaline electrode 8mL, acid electrode 17 ~ 50mL. CaO in the number of basic slag, slag desulfurization capacity, and the deposited metal thermal crack ability. Moreover, the alkaline electrode due to the low content of oxygen and hydrogen in the weld metal, non-metallic inclusions less, with high ductility and impact toughness. Alkaline electrode due to the drug skin contain more fluorite, arc stability, the general use of the DCRP, only when the drug skin contains higher amounts of stable arc agent, AC and DC dual-use. AlkalineAluminium Welding Rod are generally used for welded structures, such as to withstand the dynamic load or rigid structure. Universal electrode
