鑄造是機械制造的基礎工藝技術，由于種種原因在生產過程中會存在缺點，廢品率較高。另外，在各種機械裝備中的鑄鐵件在使用過程中極易損壞。由于鑄鐵的焊接性差，焊后常有氣孔，易變形，易斷裂，易產生白口化和焊接裂紋，從而給鑄件的修復產生相當?shù)碾y度。到目前為止，國際國內對此尚沒有解決的理論及方法。C808鑄鐵常溫焊接焊絲，經實踐證明能有效地解決了鑄鐵件在焊接過程中產生的上述問題，得到了用戶的一致好評。C808鑄鐵常溫焊接焊絲可從理論及工藝上解決以下幾個方面的問題：（1）白口問題C808鑄鐵常溫焊接焊絲，采用CO2保護半自動焊接技術，電流密度大，焊后冷卻速度快，母材與焊絲熔合區(qū)硬化層從金相分析看，白口層分析是斷續(xù)的，厚度均〈。（按照國際慣例，白口層厚度如果〈1mm，對鑄件加工切削刀具無影響，基本可以忽略不計）。（2）焊接產生熱裂紋的問題∶通常對鑄鐵件的焊補，一般都要對所焊鑄鐵件進行局部快速加熱，加熱過程中溫度不均是必然的，當熱應力大于被焊件鑄鐵抗拉強度時，就必然產生熱裂紋。在設計C808鑄鐵常溫焊接焊絲化學成分時，使用屈服極限比較低可<200MPa，比較高可達400-500MPa，對在焊接過程中產生應力并超過200MPA時。?焊絲焊補時熱影響區(qū)非常小，不會產生內應力。</p><div

藥芯焊絲焊接時比CO2實芯焊絲的飛濺要小得多，下圖為藥芯焊絲與CO2實芯焊絲飛濺大小的比較。焊接質量好一般CO2實芯焊絲只適合于低碳鋼或強度級別較低的低合金鋼的焊接，而藥芯焊絲則適用于各種材料的焊接，不僅包括各種結構鋼，也包括不銹鋼等特殊材料。藥芯焊絲焊縫的低溫沖擊韌度比實芯焊絲有了很大的提高，可適用于各種重要結構的焊接，而CO2實芯焊絲一般只用于0度以上工作的一般鋼結構。綜合焊接成本：低藥芯焊絲相對價格較高，但其綜合生產成本比焊條電弧焊要低許多，與CO2實芯焊絲大體相當。藥芯焊絲的型號及牌號按GB10045—88規(guī)怎定，藥芯焊絲第.一部分以英文字母“EF”表示藥芯焊絲代號，代號后面的第.一位數(shù)字表示主要適用的焊接位置：“0”表示用于平焊和橫焊，“1”表示用于全位置焊。代號后面的第二位數(shù)字或英文字母為分類代號。第二部分在短橫線后用四位數(shù)字表示焊縫金屬的力學性能。如焊絲型號EF03-5042。實際生產中還經常用牌號來表示藥芯焊絲的類型。藥芯焊絲生產牌號用如下符號表示：首字母“Y”表示藥芯焊絲；第二位字母表示藥芯焊絲種類，第.一、第二位數(shù)字表示焊絲特點；第三位數(shù)字表示溶渣類型（或第三位以后之數(shù)字及元素符號表示焊縫金屬化學成分）。?鉬、鉻、碳、錳、鎳及釩等合金元素的添加，可以提高（改善）熔填金屬的強度、延性、硬度及韌性等。蘇州卡斯特林焊條焊絲價格</p><p
