摘　　要：研发的加氢反应器用不锈钢带极堆焊JWF304D、JWF205D焊剂具有优良的焊接工艺性能,适用于30~90 mm宽焊带施焊。可根据不同的制造工艺进行调整,适用于多种制造工艺堆焊。焊接时飞溅小(针对于电渣焊)、脱渣优良、焊道成形质量好。埋弧焊用焊剂JWF304D焊接参数调整范围大,不但适合于90 mm宽带大电流焊接,而且适合小电流薄层快速焊。电渣焊用焊剂JWF205D可实现快速堆焊,在电流、电压适宜的情况下,堆焊速度可达27 cm/min,提高了生产效率。两种焊剂均实现了一剂多带,可配合EQ309L、EQ308L、EQ347L等多种型号不锈钢焊带使用,所得堆焊层的化学成分及各项性能指标均符合相关标准规定及用户技术协议要求。Stainless steel strip surfacing flux JWF304 D and JWF205 D for hydrogenation reactor have excellent welding process performance, which are suitable for 30 ~90 mm wide band welding. They can be adjusted according to different manufacturing process and are suitable for various of manufacturing process. They have the characteristics of small spatter during welding(for electroslag welding), excellent slag removal and good weld bead forming quality. Welding parameter adjustment range of submerged arc flux JWF304 D is large, not only suitable for high current with 90 mm wide band, but also suitable for small current, thin layer, rapid welding. The flux JWF205 D for electroslag welding can be welded at high welding speed, with suitable current and voltage, the surfacing speed can reach 27 cm/min, which improves the production efficiency. Both of the two fluxes can be welded by combining with a variety of welding strips,which can be used with EQ309 L, EQ308 L,EQ347 L and other types of stainless steel welding strips. The chemical composition and various performance of the surfacing layer meet the requirements of relevant standards and user’s technical agreements.
