电焊条①特点：药皮含大量氧化铁和较多的锰铁，焊条熔化速度快，焊接生产率较高，电弧稳定， 引弧容易，熔深较深，脱渣性好，但飞溅大，熔敷金属的抗裂性能较好。适用于中等以上厚 度的钢板平焊，而立焊、仰焊操作性差。 ②药皮组成物用量范围（%） 硅酸盐 35～45 碳酸盐 0～3 二氧化钛 0～12 铁合金 29～35 钛铁矿 24～30 有机物 0～5 ③药皮成分范围（%） SiO 35～40 TiO < 10 MnO16～18 FeO 30～35 MgO<5 AI O <4 CaO<3 2 2 2 3 挥发成分<2 ④焊接熔渣凝固温度范围（℃） 1180～1350 ⑤举例 氧化铁型 E4320(J424) 药皮中含有多量的氧化铁及较多的锰铁脱氧剂，电弧吹力大， 再引弧容易，脱渣性好，焊缝致密，略带凹度，焊接时飞溅稍大。适用于平焊及平角焊。 氧化铁型E4322(J424)工艺性能基本与E4320 相近，但焊缝较凸，不均匀。

Welding wire (1) features: medicine skin contains large amounts of iron oxide and more ferromanganese, melting speed, welding rod productivity is higher, electric arc stability, easy arc starting, the depth is deep, slag off of good, but the big splash, deposited metal melting the anti-cracking performance is better. Apply to medium above the thick degrees, and stand welding welding steel flat, back welding operational difference. (2) the amount of drug skin that range (%) silicate 35 to 45 carbonate 0 ~ 3 titanium dioxide 0 ~ 12 ferroalloy 29 ~ 35 titanium iron ore 24 ~ 30 organic 0 ~ 5 (3) medicine composition range (%) skin SiO 35 to 40 TiO < 10 MnO16 ~ 18 FeO 30 to 35 MgO AI O < < 5 4 3 2 2 2 CaO < < 2 (4) 3 volatile components welding slag solidification temperature range (℃) 1180 ~ 1350 (5) type, for example E4320 ferric oxide (J424) drug skin contains many amount of iron oxide and more ferromanganese deoxidizer, arc blow force big, again easy arc starting, take off of good slag, weld density, slightly concave degrees, welding bigger splash. Welding and welding to be done in a flat. Iron oxide type E4322 (J424) process performance of basic and E4320 close, but weld a convex, not uniform.
