ST-SF系列焊剂执行GB/T5293-1999标准,粒度12-60目,配合ST-WELD系列药芯焊丝使用。焊剂使用前需经350℃,1-2h烘干。焊剂多次重复使用后应经12-60目筛选,以去除细粉及混入的焊渣、杂物,保证焊接质量。 | ST-SF series flux accords with the GB/T5293-1999,and its granularity is from 12 meshes to 60 meshes,The flux is used with ST-WELD series flux-cored wires . Before the flux is used ,it should be dried at 350℃ for 1-2h.The flux can be multi-used.Before used,the flux should be filtered by a through a sieve with 12 to 60 meshes in order to get rid of welding slag and impurities. | ||
