Item Details

  • Coreshield 40 is a self-shielded flux cored wire primarily designed for multiple pass, horizontal and flat position welding of low and medium carbon steels when toughness is not a requirement. The larger sizes achieve very high deposit rates for very low joining costs. The low penetration, convex fillet bead shape and ability for the slag to desulfurize the deposit make it an ideal choice when crack resistance is a primary consideration. The flat position deposits are smooth and uniform with good wetting into the side walls. The core ingredients are carefully balanced to stabilize the droplet transfer, enhance the ability to handle mill scale and easily detach the slag for quick cleaning.


  • Coreshield 40 is designed to operate on DCEP (electrode positive) with longer electrical stickout
  • The longer extension increases the deposit potential by preheating the wire
  • The percent of the melt-off converted to fumes, although higher than Dual Shield wires, is reasonably low and the fume can be removed at the source
