Characteristics and Application

AWS A5.20 E70T-7 Flux Cored Arc Welding Wire is a self-shielded flux cored wire designed for high penetration welding. It is suitable for flat, horizontal and downhill positions on DCEN polarity. Excellent performance on X-ray inspection, and desulfuration reduces cracking in welding thick plates, constrained joints and medium-carbon steel. The typical applications are general fabrication and structural weldment where high deposition with good penetration and / or fast travel speed is needed. Available positions are flat weld, horizontal weld and vertical down ones of welding for fillet weld and lap joint.
