必須注意以下幾個(gè)問(wèn)題：①電弧冷焊冷卻速度快,球墨鑄鐵中的球化劑嚴(yán)重阻礙石墨化過(guò)程,焊縫容易出現(xiàn)白口組織;電弧冷焊時(shí)出現(xiàn)的白口組織不僅影響機(jī)械加工,而且收縮率大,焊接變形大,在焊接應(yīng)力作用下,焊縫極易產(chǎn)生裂紋,靠近球墨鑄鐵母材一側(cè)的焊縫裂紋傾向尤為嚴(yán)重。②為防止異質(zhì)焊縫出現(xiàn)白口組織,通常選用高釩焊條和鎳鐵焊條,如選用Z408焊條或Z438焊條,焊縫的抗裂性能和機(jī)械加工性能明顯地得到改善。③焊前選用直徑。堆焊過(guò)渡層的工藝參數(shù)為:焊接電壓18~20V,焊接電流95~105A,焊接速度。為了確保堆焊層質(zhì)量,兩個(gè)相鄰堆焊焊道的寬度應(yīng)重疊1/3為佳。④電弧冷焊時(shí),將堆焊好的球墨鑄鐵件與碳鋼嚴(yán)格定位,接頭根部間隙為3~8mm,然后用E5016(J506)或E5015(J507)焊條進(jìn)行焊接,為了防止焊接接頭處產(chǎn)生角變形，應(yīng)進(jìn)行雙面焊。⑤球墨鑄鐵焊后應(yīng)立即放入593~649℃的加熱爐中,升溫到899℃,保溫2~4h,冷卻到704℃時(shí)保溫5h,再爐冷到593℃,然后在空氣中冷卻,有利于獲得好的效果。如圖為球墨鑄鐵與碳鋼的焊接接頭,先用鎳基焊條在球鐵坡口上堆焊過(guò)渡層,然后將碳鋼板與之裝配,留有足夠間隙,如圖間隙為3mm，***采J506焊條將焊縫焊滿。(2)CO2氣體保護(hù)焊以汽車傳動(dòng)軸萬(wàn)向節(jié)球墨鑄鐵。天山區(qū)球墨鑄鐵管銷售廠家</p><p
