| Abstract: | According to the welding technological requirement of West-to-East Gas Transportation Project,an experimental research was performed in this paper on gas shielded arc welding of 10.3mm thick X70 pipe steel produced in Wuhan Iron & Steel (Group) Corporation. The welding materials are high toughness welding wire WER60 and rich argon shielding gas. The results show the weld has good properties in strength and toughness satisfying the welding demands of pipeline. |
