必須注意以下幾個問題：①電弧冷焊冷卻速度快,球墨鑄鐵中的球化劑嚴重阻礙石墨化過程,焊縫容易出現(xiàn)白口組織;電弧冷焊時出現(xiàn)的白口組織不僅影響機械加工,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械加工性能明顯地得到改善。③焊前選用直徑。堆焊過渡層的工藝參數(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,兩個相鄰堆焊焊道的寬度應(yīng)重疊1/3為佳。④電弧冷焊時,將堆焊好的球墨鑄鐵件與碳鋼嚴格定位,接頭根部間隙為3~8mm,然后用E5016(J506)或E5015(J507)焊條進行焊接,為了防止焊接接頭處產(chǎn)生角變形，水磨溝區(qū)球墨鑄鐵管廠家供應(yīng)，應(yīng)進行雙面焊。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，水磨溝區(qū)球墨鑄鐵管廠家供應(yīng),冷卻到704℃時保溫5h,再爐冷到593℃,然后在空氣中冷卻,有利于獲得好的效果，水磨溝區(qū)球墨鑄鐵管廠家供應(yīng)。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氣體保護焊以汽車傳動軸萬向節(jié)球墨鑄鐵。阿克蘇球墨鑄鐵水篦子廠。水磨溝區(qū)球墨鑄鐵管廠家供應(yīng)</p><div

大中小球墨鑄鐵的焊接2015-07-08dongchang展開全文球墨鑄鐵是在熔煉過程中加入一定量的球化劑，使石墨以球狀存在，從而使力學(xué)性能明顯提高。1.球墨鑄鐵的焊接性球墨鑄鐵焊接性與灰鑄鐵有相同的一面，但又有其自身的一些特點。這主要表現(xiàn)在兩方面。(1)球墨鑄鐵的白口化傾向及淬硬傾向比灰鑄鐵大，這是因為球化劑(當(dāng)其加入量已可穩(wěn)定獲得球狀石墨時)有阻礙石墨化及提高淬硬臨界冷卻速度的作用，所以，在焊接球墨鑄鐵時，同質(zhì)焊縫及半熔化區(qū)更易形成白口，奧氏體區(qū)更易出現(xiàn)馬氏體組織。(2)由于球鐵的強度、塑性與韌性比灰鑄鐵高，故對焊接接頭的力學(xué)性能要求也相應(yīng)提高，常要求與各強度等級球墨鑄鐵母材相匹配。2.球墨鑄鐵電弧補焊球墨鑄鐵電弧補焊采用同質(zhì)及異質(zhì)焊條，同質(zhì)焊條又有鋼芯與鑄芯之別。異質(zhì)焊條則采用鎳基焊條(Z408)及高釩焊條，對于不重要的部位也可以采用低碳鋼焊條，如J506、J422等。球墨鑄鐵通常應(yīng)用于比較重要的場合，采用同質(zhì)焊條焊接時應(yīng)保證焊縫球化，力學(xué)性能達到規(guī)定的指標，應(yīng)盡量降低白口傾向，提高抗裂性。(1)Z238焊條電弧熱焊。Z238焊條為低碳鋼焊芯，藥皮中加入球化劑及石墨化劑，在一定工藝條件下，焊縫中的石墨可成為球狀。</p><p
