The weldability of austenitic aged steel in 0018Ni high strength austenitic deposition rigidification was researched. The welding technical parameters were discussed by using automatic tungsten electrode argon arc welding for thin wall spinning pressure barrel-shape parts. The influences about mechanical properties and microstructure of argon weld joint by different heat treatment techniques were compared and analyzed. The result showed that there were some fine grains included mass intermetallic compound deposition strengthen particle in welding and heating area, weld joints and parent material are excellentwith high strength and toughness.
