The main features are that the back surface weiding seams are even , smooth and weld edge tidy , excellent in performances of welding technology and welding seam dynamics 主要特点是背面焊缝匀称、光滑,焊趾整齐,焊接工艺性能及焊缝力学性能优良。
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 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。
