E-80M
Description:
E-80M metal cored wire combines the advantages of small amount of solid wire, high efficiency and common flux-cored wire melting speed, small splash, good welding process performance, large arc penetration, beautiful weld appearance, high speed , Efficient welding characteristics, deposited metal diffusion of low hydrogen content, low temperature impact resistance and crack resistance.
use:
It is suitable for semi-automatic and full-automatic welding of long-distance pipelines. It is used for root welding, filling and capping of X80 pipeline steel. It can also be applied to automatization of automobile, construction machinery and other industries.
