AWSA5.20 E71T-1 is flux-cored welding wire, a basic rutile, general purpose, micro-alloyed, gas shielded flux-cored welding wire designed for all-position welding of mild steel in applications requiring moderate levels of strength and very good notch toughness；

AWS A5.18 ER70S-6 Gas-shielded welding wires utilize Co2 argon-rich gas and argon gas as the shielding gases with high production efficiency. Large current to be used during welding to achieve droplet transfer, with large melting coefficient of wire, excellent depth of welding penetration on materials, little melting residues, high-density current, concentrated hear, small heating area, little distortion of work pieces after welding,etc.

CHWS-S1(H08A AWS A5.17 EL12) A low-carbon, low-manganese, low-silicon general purpose submerged arc wire, primarily used for multi-pass welding. However, the product is capable of making single pass welds.
