Iron powder for welding electrode

Iron powder electrode is to improve the efficiency of electrode deposition, add a certain amount of electrode in coated with reduced iron powder deposition efficiency in more than 105% of the electrode Its characteristic is that a lot of heat when iron powder is heated oxidation, become except arc heat source, which can improve the operation of the electrode process performance, improve the deposition efficiency Below 30% for the amount of iron powder, add iron powder is mainly to improve welding technology, such as E5018 type iron powder addition amount is more than 30%, and appropriately increase the coating thickness, can greatly improve the deposition efficiency of welding rodThe latter is often called high efficiency iron powder electrode, the deposition efficiency of up to 160%, up to 250% iron powder electrode generally has good process performance, mainly used for flat welding and fillet welding.
