The Welding Wire China drying should be aware of the following:

(1) low-hydrogen electrodes at room temperature more than 4h, should be re-drying. Repeat drying Views should not be more than three times.

(2) drying Welding Wire, it is prohibited to put the welding rod suddenly high temperature furnace, or removed from the high-temperature furnace suddenly cooled, to prevent electrode due to cold and hot temperatures drug leather cracking phenomenon.

(3) the electrode drying should should be on the record  record grades, batch number, temperature, time, and content.

(4) during the electrode drying, technical personnel should be responsible, responsible for the operation, inspection and checking, not less than once each batch of electrodes, and the signature on the operating record.

(5) drying electrodes, the electrodes should not be into a crib or a bundle stacked, should be laying into layered stacked each layer electrode can not be too thick (generally 1 to 3 layers) to avoid electrode drying unevenly heated and moisture is not easy to rule out.

(6) The open-air operation, the electrodes must be safekeeping, does not allow the open storage of low-temperature oven thermostat to save, or even the next day before use to re-drying.       Requirements of electrode baking: the electrode baking requirements Manual manual are subject to the following requirements. Electrode Repeat baking no more than twice, the acid coated electrode baking temperature to 120 of 150 ° C, holding time 1h, low alkaline hydrogen type welding electrode baking temperature of 350 ° C, holding time 1h
