德国卡斯特林Castolin美国MG210铸铁焊条

MG 210 Maximum strength alloy for cast iron

铸铁用MG 210 最大强度焊条

 

GENERAL CHARACTERISTICS:

特点：

Welds produced by this electrode are high strength, crack resistant, porosity free yet, machinable when applied to a wide variety of cast irons. The special core wire has a high current carrying capacity and the coating is designed to convert the impurities of the base metal into slag instead of being entrapped in the deposit. The soft arc prevents deep penetration, therefore the weld is easily machined.

这种焊条产生的焊缝强度高、抗裂、无气孔，应用于各种铸铁时焊缝可加工。特殊焊芯具有高载流能力，涂层设计用于将母材中的杂质转化为熔渣，而不是滞留在沉积物中。柔性电弧可防止深熔透，因此焊缝易于加工。

 

APPLICATIONS:

应用：

For fabrication and difficult repair of all gray and alloyed cast irons. Recommended for welding cylinder heads, machine bases, gear housings, cams, levers, filling holes, repairing teeth of cast gears and building up or replacing missing sections. Commonly used to weld ductile iron, “Ni-Resist” and “Meehanite” to themselves or to steel. Also suitable for joining nickel alloys to gray cast iron, malleable cast iron and cast steel.

适用于所有灰色和合金铸铁的制造和难以修复场合。建议用于焊接气缸盖、机器底座、齿轮箱、凸轮、杆类、填充孔、铸造轮齿修复以及堆焊或更换缺失部分。通常用于将球墨铸铁、耐蚀高镍铸铁和孕育铸铁间焊接或与钢的焊接。也适用于将镍合金连接到灰铸铁、可锻铸铁和铸钢上。

PROCEDURE程序：

Clean weld area if possible. Remove surface skin and all sharp edges. Bevel joint to form a “U” groove. A bead hole must be welded at right angles to each end of all cracks to prevent spreading during welding. Use low amperage and maintain a short arc. Short stringer beads or narrow weave beads should be used to prevent excessive heat build-up. When breaking the arc always fill the crater and drag rod back over the weld deposit. Peening while still hot will help reduce stresses. When re-striking the arc start on previously deposited weld metal, not on the base material. Allow part to cool slowly.

如有可能，清洁焊接区域。去除表面外层和所有锐边。坡口接头，形成“U”形槽。焊珠孔必须与所有裂纹的两端成直角焊接，以防止焊接过程中扩散。使用低电流并保持短电弧。应使用短线状焊道或窄交织焊道，以防止过热。断开电弧时，始终填充焊口，并将焊条拉回到熔敷层上方。趁热锤击将有助于降低应力。重新引弧时，电弧从先前熔敷的焊缝金属开始，而不是从母材开始。让零件慢慢冷却。
