P500QL2 is a quenched and tempered weldable fine grain steel of flat products used for pressure vessel in EN 10028-6 standard. For its characteristics and applied environmental requirements, the welding process qualification test for P500QL2 steel with 52 mm wall thickness was carried out by SMAW and SAW, and the mechanical properties of welded joints were studied by tension, bend, impact, hardness and macroscopic tests. The results showed that adopting appropriate welding process scheme can obtain welded joints with excellent mechanical properties for P500QL2 steel, and this welding procedure scheme is successfully applied to the body manufacturing of underwater separator.
