Hydropower780MPaShielded Metal Arc Welding


JL-F80CL		GB/T 32533 E7815-G
AWS A5.5 E11018-G		JL-80CL is an ultra-low hydrogen, high-toughness welding electrode with a low-hydrogen sodium-type flux coating. It is used for welding critical structures made of high-strength steel of corresponding strength grades, such as hydroelectric power station risers and offshore engineering applications. It serves as an excellent matching welding electrode for SX780CF steel.
Active Gas Shielded Arc WeldingJL-ER80-GGB/T 39281 G76A4 M21 ZN5M3
ER76-G(ER110S-G)		JL-ER80-G is a copper-coated gas-shielded welding wire for 800 MPa-grade low-alloy high-strength steels. It is widely used for welding 780 MPa-grade low-alloy high-strength steels with full-argon gas shielded arc welding in various fields such as bridges, marine engineering, ships, boilers and pressure vessels, and pressure pipelines.
Submerged Arc WeldingJL-WH08Mn2Ni2MoA/JL-SJ606F76A4-H08Mn2Ni2MoA
(F76A4-EM4-M4)		JL-WH08Mn2Ni2MoA is a high-strength steel submerged arc welding flux. JL-SJ606 is a fluoride-alkali type low-hydrogen sintered flux, primarily used for welding 780MPa-grade high-strength steels such as 780CF steel.
Flux-Cored Arc WeldingJL-F111K3T76 4 T1-1 C1 A-N3M2
(E111T1-K3C)		JL-F111K3 is a rutile-type flux-cored wire for CO₂ gas shielded welding. It is used for welding 780MPa-grade high-strength structural steel and is suitable for all-position welding, offering excellent processability and mechanical properties.
