焊條烘干的目的焊條在儲存、運輸期間藥皮會吸潮，使藥皮中的水分增加。焊條使用前進(jìn)行烘干的作用就是降低藥此中的含水量，其目的是：1）減少焊接過程中的飛濺，使焊接電弧能夠穩(wěn)定地燃燒。2）防止在焊縫中產(chǎn)生氣孔。3）防止產(chǎn)生在焊接某些低合金鋼時由氫引起的延遲裂紋。根據(jù)JB3223—83《焊條質(zhì)量管理規(guī)程》的規(guī)定，酸性焊條烘干的溫度為75～150℃時間為1～2h。酸性焊條由于對水分產(chǎn)生氣孔的敏感性不大，所以烘干溫度相對要低一些。堿性焊條的烘干溫度350--400℃，時間1--2小時，烘干后放在100--150℃的保溫箱內(nèi)，隨用隨取。JB4709中有推薦保溫時間和溫度(非強制性標(biāo)準(zhǔn)),不過實際使用時比較好參考焊條質(zhì)保書中的溫度及時間要求！堿性焊條過高的烘干溫度也是不合適的：一是浪費能源；其次是當(dāng)烘干溫度超過500℃時，藥皮中的某些成分（如CaCO3）就要發(fā)生分解，起不到應(yīng)有的保護(hù)作用。焊條烘干時的注意事項焊條烘干時應(yīng)注意如下事項：1）低氫型焊條在常溫下超過4h時，應(yīng)重新烘干。重復(fù)烘干次數(shù)不宜超過3次。2）烘干焊條時，蘇州焊絲生產(chǎn)廠，禁止將焊條突然放進(jìn)高溫爐內(nèi)，或從高溫爐中突然取出冷卻，蘇州焊絲生產(chǎn)廠，防止焊條因驟冷驟熱而發(fā)生的藥皮開裂現(xiàn)象，蘇州焊絲生產(chǎn)廠。3）焊條烘干時應(yīng)作記錄。通常成卷絲材均以塑膠套包封后并放置干燥劑使避免材料受潮，包封后的材料再放入硬紙盒內(nèi)送出。蘇州焊絲生產(chǎn)廠</p><div
