welding wire

With excellent welding technological properties, stable arc, less spatter, beautiful bead and a higher deposition efficiency.

  Co2 Welding Wire (AWS ER 70S-6)

Widely applied to all kinds of fields like automotive industry, construction machinery production, shipbuilding, metallurgical equipment production, bridges, civil works, petrochemical industry, production of pressure vessels of boilers, locomotive vehicles, etc. Some of its characteristics are as follows: 1. Low welding costs. 2. High productivity and low electricity consumption. 3. Easy to operate. All-position welding. 4. Very low hydrogen content in the weld and lower nitrogen content. Excellent crack-resistance. 5. Little deformation after welding. 6. Wide applicability. Suitable for welding thin, medium and thick plates.
