Introduction:

The welding current has been strengthened to a great extent and the welding efficiency has been improved. Because the grains of the deposited metal have been refined, both the tensile strength and the yield strength are close to the upper limit of the standard of classification society for 50KG calss welding materials. The impact absorded energy has been improved obviously.

Application:

Used for welding all kinds of 500MPa structural steel parts, thick plates and thick pipelines.
Used for high speed welding on 500Mpa base metals.
