能使焊縫產(chǎn)生變形并使應力下降，從而***地防止熱裂紋的出現(xiàn)。（3）熔合性問題∶有些鑄鐵，由于“石墨”粗大，在高溫或者油環(huán)境中工作，在焊補過程中會有一定程度影響熔合性，嚴重時出現(xiàn)打滾而無法焊接。本焊絲焊補過程中能促使“石墨”燃燒，燃燒產(chǎn)生的CO可促使熔池沸騰而使熔合性**改變，焊接后焊縫組.織能跟基體組.織完全融合或部分熔合，結(jié)合緊密。（4）焊前不予熱，焊后不需熱處理消除應力或退火降低加工區(qū)硬度問題。由于C808鑄鐵常溫焊接焊絲及焊接工藝上的改進，采取在焊縫兩端覆蓋退火焊道，消除了基材中的熱應力集中點，焊接后不需進行消除應力或退火降低加工區(qū)硬度熱處理。C808常溫鑄鐵焊接焊絲對鑄鐵件加工面缺點進行修復的方法在待焊部位開出坡口，坡口表面加工,使表面光澤，便于使焊接電弧燒到坡口面的任何地方，對焊后凡要加工的地方，均用退火焊道覆蓋，焊接規(guī)范的選用原則為在確保熔合的前提下，采用本焊絲和小電流(40-60A)的CO2氣體保護常溫焊接，焊接工作按鑄鐵常溫焊接要領進行。采用C808常溫鑄鐵焊接焊絲對鑄鐵件加工面缺點進行修復獨到之處焊前不預熱，焊后也不需熱處理，焊后可直接上機械加工線進行切削加工，包括能在焊區(qū)鉆小孔和攻絲。?熔滴的過渡多以球滴過渡為主，飛濺較多。江蘇日亞焊條焊絲廠</p><p
