2）焊絲端部應(yīng)始終處于氬氣保護(hù)之中，防止合金元素的氧化、燒損。為使熔渣盡快浮出，根據(jù)情況可用焊絲對高溫熔池進(jìn)行適當(dāng)攪拌，不宜依靠降低焊速來促使熔渣浮出。焊后在焊縫表面形成的熔渣薄而脆，高溫時極易自行脫落，故焊接時應(yīng)戴好防護(hù)眼鏡，防止灼傷眼睛。（3）要獲得美觀均勻的焊縫很大程度上取決于正確掌握熔池的溫度。當(dāng)發(fā)現(xiàn)熔池增大出現(xiàn)下凹，說明熔池溫度過高，這時應(yīng)迅速減少焊與工件的夾角，并加快焊接速度。當(dāng)熔池小焊縫窄而高時，說明熔池溫度低，這時應(yīng)增大焊與工件的夾角，減慢焊接速度，減少焊絲添加量。（4）1Cr18Ni9不銹鋼在450~800℃溫度區(qū)加熱，常發(fā)生沿晶界的腐蝕破壞，稱為晶間腐蝕。為防止打底層焊縫金屬產(chǎn)生晶間腐蝕，應(yīng)以快焊快冷為原則，盡量采用小的焊接熱輸入、快速焊、短弧焊、小幅擺動。（5）焊接時焊要等速移動，禁止抖動。焊絲與工件表面的夾角在25°左右，既可保證藥芯焊絲冶金反應(yīng)的充分性，又可避免填充金屬的過熱。鎢極端頭與熔池表面的距離應(yīng)保持在3mm左右，使操作者的視線寬廣，送絲方便，避免焊縫夾鎢。（6）為避免在接頭收弧時產(chǎn)生縮孔，應(yīng)盡量采用短弧焊，焊擺動要均勻，要保證藥芯焊絲的焊接冶金反應(yīng)過程和脫渣過程充分進(jìn)行。上海小池酸素焊條焊絲廠藥芯焊絲可用于碳鋼，低合金高張力鋼，**度淬火回火鋼，不銹鋼以及硬面耐磨鋼材等的焊接。</p><div
