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

As the most harmful type of welding defects, welding cracks seriously affect the performance and safety reliability of welded structures.-----

1) It has a wide welding current adjustment range, which can weld both thin and thick parts.
