铸铁是碳的质量分数大于2.14%的Fe-C合金。实际上工业铸铁一般是Fe-C-Si为主的多元合金。铸铁通常是按照碳在铸铁中的分布形态进行分类,一般可分为白口铸铁、灰铸铁、球墨铸铁、蠕墨铸铁和可锻铸铁。由于铸铁含碳量高、组织不均、塑性低、焊接性不良,在焊接过程中极易产生白口、裂纹和气孔等缺陷,在焊接时应特别注意焊接工艺和焊接材料的选用。对焊条电弧焊来说,目前国内可供选用的焊条有20余种,基本上可分为两大类,一类是同质焊缝型即铸铁型;另一类则是异质焊缝型如:钢(碳钢或者合金结构钢等)、纯Ni、Ni-Fe、Ni-Cu、Ni-Fe-Cu、Fe-Cu等。 portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">Z308铸铁焊条符合 GB EZNi-1相当 AWS ENi-C1 portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">说明: Z308是纯镍焊芯、强还原性石墨型药皮的铸铁焊条,施焊时,焊件可不预热,具有良好的抗裂性能和加工性能。镍价格昂贵,应该在其它焊条不能满足时才可选用。交直流两用。 portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">用途: 用于铸铁薄件及加工面的补焊,如发动机座、机床导轨、齿轮座等重要灰口铸铁件。 portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">熔敷金属化学成分(%) portant; color: rgb(86, 86, 86) !important;">化学成分CMnSiSNiFe其它元素总量保证值≤2.00≤1.00≤2.50≤0.030≥90≤8≤1.00 portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">参考电流 (AC、DC+) portant; color: rgb(86, 86, 86) !important;">焊条直径(mm)φ2.5φ3.2φ4.0φ5.0焊接电流(A)50~10070~120110~180160~190 portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">注意事项: portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">Z408铸铁焊条 符合 GB EZNiFe-1 相当 AWS ENiFe-C1 portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">说明: Z408是镍铁合金焊芯,强还原性石墨药皮的铸铁焊条,具有强度高、塑性好、线膨胀系数低等特点。抗裂性对灰口铸铁与Z308差不多,但对球墨铸铁则比Z308强,对含磷量高(0.2%P)的铸铁,也具有良好的效果,切削加工性能比Z308和Z508稍差。用于常温或稍经预热(至200℃左右)灰口铸铁及球墨铸铁的焊接。交直流两用。 portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">用途: 适用于重要高强度灰口铸件及球墨铸件的补焊。如汽缸、发动机座、齿轮、轧辊等。 portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">熔敷金属化学成分(%) portant; color: rgb(86, 86, 86) !important;">化学成分CMnSiSNiFe其它元素总量保证值≤2.00≤1.80≤2.50≤0.03045~60余量≤1.00 portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">参考电流 (AC、DC+) portant; color: rgb(86, 86, 86) !important;">焊条直径(mm)φ3.2φ4.0φ5.0焊接电流(A)50~10070~120110~180 portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">注意事项: portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">Z408A铸铁焊条 portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">型号GB/T:EZNiFe-Cu portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">说明:镍铁铜合金焊芯、强还原性强石墨化的铸铁焊条,交、直流两用,可全位置焊,具有强度高、塑性好、与母材熔合性好等特点,切割性Z408相似,电弧稳定,焊条不发红,工艺性好,相当于瑞士卡斯特林公司2240焊条。 portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">用途:用于重要的高强度灰口铸铁及球墨铸铁的焊补,如汽缸、发动机、座齿轮等。 portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">熔敷金属化学成份/% portant; font-variant-numeric: normal !important; font-variant-east-asian: normal !important; font-stretch: normal !important; line-height: 24px !important; color: rgb(86, 86, 86) !important;">C≤2 Si≤2.
