The formation, mechanical properties and intergranular corrosion character of welded joint were inspected on the S30408 stainless steel welding joint under the condition of active welding process. The results show that the penetration increases signiifcantly, both positive and negative (back) side mold well with simple process. The strength, plasticity and hardness of joints meets the requirement. The average ferrite content reached 10.8% in the weld zone after intergranular corrosion. Joint has excellent corrosion resistance.
