Select ECF3
Low Alloy / Submerged Arc / Flux Shielded
Features
- Intended for single and multiple pass welding of high strength low alloy (HSLA) and micro-alloyed steels where a combination of 100 ksi tensile strength and excellent notch toughness are required.
- Higher deposition rates than solid wire when run at the same current level
- Exhibits a broader and shallower bead profile than when using solid wire, reducing the tendency for burn through
- Capable of running directly over root passes with proper procedure – eliminating requirement for a hot pass
- Easy slag removal – reduces post weld cleanup time
- Typical applications include welding of high strength steel such as 4130 where extended PWHT is required, offshore oil equipment, sour gas applications, storage tanks, pressure vessels
- Arcflux BF-10MW is the recommended flux. Other neutral fluxes with high basicity can be used as well.
