1. Đặc điểm và ứng dụng:         
  • GL - 78 is an iron powder low hydrogen type covered electrode with excellent usability in all position welding.
  • GL- 78 is suitable for high tensile strength carbon and alloyed steel in ships, bridges, building, and pressure vessels. 
  • It's easy-slag-removable, few blowhole, smoke and spatter. Its weld bead is smooth, shinny; the arc is soft, the re-striking is good and penetration is shallow...especially having perfect result with AC current.
