Explanation: JH-WQ3 is a high strength submerged welding wire,used with submerged welding fluxes(especially JH-SJ101,JH-SJ101G,JH-SJ101q,etc.series agglomerated fluxes) in submerged welding,resulting in perfect deposit metal mechanical properties.
Applications:Applied with JH-SJ101 ,JH-SJ101G,JH-SJ101q,etc.agglomerated fluxes,
Mainly used in the welding of some low alloy steel(like X70,X80,HG70,A70,etc.)
Structures, like the submerged welding of oil transportation pipe lines and steels used for engineering machines.It has perfect deposit metal low temperature impact toughness and 620~750 MPatensile strength.
