【摘要】 在酸性渣系的基础上，通过添加少量氧化物，调整熔渣的流动性，并加入微量的强脱氧剂，以增强背面焊缝的保护，研制成功一种背面不充氩的不锈钢打底单面焊双面成形专用药芯焊丝。更多还原

【Abstract】 A kind of stainless steel flux - cored wire has been successfully developed, based on acid slag type system, by adding a bit of oxides and trace of deoxidizer,adjusting the fluidity of melting slag to increase shielding of the back weld. Welding using this kind Of wire does not need argon in the back of the weld.更多还原
