大中小球墨鑄鐵的焊接2015-07-08dongchang展開(kāi)全文球墨鑄鐵是在熔煉過(guò)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(diǎn)。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?yàn)榍蚧瘎?當(dāng)其加入量已可穩(wěn)定獲得球狀石墨時(shí))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(shí)，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(qiáng)度、塑性與韌性比灰鑄鐵高，故對(duì)焊接接頭的力學(xué)性能要求也相應(yīng)提高，常要求與各強(qiáng)度等級(jí)球墨鑄鐵母材相匹配。2.球墨鑄鐵電弧補(bǔ)焊球墨鑄鐵電弧補(bǔ)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(duì)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(chǎng)合，采用同質(zhì)焊條焊接時(shí)應(yīng)保證焊縫球化，力學(xué)性能達(dá)到規(guī)定的指標(biāo)，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。米東區(qū)球墨鑄鐵管推薦</p><p
