3 Requirements
3.1 Materials
3.1.1 Ingots used to produce products shall be smelted several times. The first smelting may be carried out in a vacuum consumable electro-arc furnace or a cold-hearth furnace, and the subsequent smelting shall be carried out in a vacuum consumable electro-arc furnace, and no elements are allowed to be added in the last smelting.
3.1.2 It is not allowed to use any recycled materials of titanium and titanium alloy as raw materials for producing ingots and processed materials.
3.1.3 Consumable electrodes shall not be welded through tungsten argon arc welding.
3.2 Chemical composition
3.2.1 The chemical compositions of the products shall meet the requirements for corresponding designation specified in GB/T 3620.1, of which, the hydrogen content shall not be greater than 0.008%.
3.2.2 During re-inspection by the purchaser, the chemical composition permissible deviation of the product shall meet those specified in GB/T 3620.2.
