ER70S-6 welding wire has long been considered the standard in MIG/MAG welding of low-carbon steel due to its excellent arc ignition, deep penetration, and ease of defect control in mass production. Viet Duc's W49-VD (AWS A5.18 ER70S-6) welding wire was created to precisely meet this need: copper-coated welding wire for CO₂ or Ar-CO₂ gas, suitable for both semi-automatic and automatic/robotic welding systems, helping to improve productivity and ensure consistent weld quality in the production line.

The W49-VD wire is particularly notable for its ability to serve applications requiring high mechanical properties. This welding wire is recommended for low-carbon and low-alloy steels, performing effectively in structures subjected to loads from 490 to 550 MPa. The welds exhibit deep penetration, high ductility, and impact resistance at temperatures as low as -30°C (with an impact value of approximately 110 J), increasing reliability when welding load-bearing components or working in low-temperature environments.
In practical production, the "strength, ductility, and penetration" characteristics of the W49-VD welding wire have made it a preferred choice in industries requiring high speed and repeatability, such as automotive, motorcycle, machinery, shipbuilding, and pressure vessel construction. With high welding productivity and the ability to weld in all positions, this wire is suitable for both workshop fabrication and construction installation.

Viet Duc is currently one of the leading names in the welding materials manufacturing industry, with over 58 years of experience and modern technology from Europe and China. With a total designed capacity of up to 25,000 tons/year, Viet Duc has been supplying welding materials to key industries in Vietnam such as shipbuilding, hydropower, thermal power, automotive manufacturing, and steel structures.
At the Viet Duc welding wire factory, the production system is invested in using Italian technology to optimize the stability of the coating, the uniformity of wire diameter, and the quality control of each product batch. As a result, the ER70S-6 W49-VD welding wire consistently maintains smooth wire feed, stable arc, and welds with uniform mechanical properties, meeting the requirements of modern industrial production.
