This type of steel as a high-strength welded structural steel, the carbon content is limited to low, usually less than 0.18% carbon mass fraction, and in the design of the alloy composition are also considered weldability requirements, so low carbon tempered steel welding is basically similar to nor

The submerged arc welding process is ideal for important applications in pipeline, pressure vessel and tank, rail fabrication and major construction, with the simplest single wire forms, double wire construction, tandem double wire construction and multi wire construction.
