抗吸潮碱性烧结焊剂的试验研究

Experimental Study on Anti-hygroscopic Basic Agglomerated Flux

介绍了一种新型高强钢埋弧焊用碱性烧结焊剂（SJ－K1）。该焊剂具有良好的工艺性能，电弧燃烧稳定，尤其是具有较强的抗吸潮性。这种焊剂配合H08A，H10Mn2或其他合金焊丝可用于低合金高强度钢焊接，并可获得氧含量和扩散氢含量低、却贝冲击韧性高的焊缝金属。

A new type basic agglomerated flux(SJ-K1)used in submerged arc welding of the high strength steels is Presented. This flux has good technology performances and stabilizes the arc better, and especially it has excellent anti- hygroscopicity. This flux, which matches HO8A, H10Mn2 or other alloy welding wire, can weld low alloy high strength steels,and can obtain excellent weld metal having lower oxygen content and diffusible hydrogen content as well as higher Charpy toughness.
