Multi-wires submerged arc welding device was adopted to study the welding technology test of X65MO submarine pipeline steel with 15.9 mm thickness produced in Shougang. The microstructure of welded joint was analyzed by using metallographic test. Tensile test, impact test, bending test, hardness test and CTOD test were applied to evaluate the welded joint mechanical performance. And HIC test was adopted to analyze the HIC corrosion resistance properties. The results showed that the mechanical and anti-corrosion properties meet the requirements of the relevant technical standards and demands of the users.
