First open the drain valve to drain the nitrogen, and then close the drain valve. Open the exhaust valve and introduce the LNG gas in the LNG tank box into the LNG tank through the unloading platform. When the pressure in the tank rises to 0.1-0.2MPa, close the exhaust valve, stabilize for 3 minutes, and open the drain valve to empty. Repeat this 2-3 times until the replacement is complete. A combustible gas detector or exhaust gas sampling can be used for ignition test to check the degree of replacement.

Liquid argon is an industrial gas with many special effects. Argon is 1.4 times heavier than air and can form a stable layer of airflow above the molten pool, which has good protective properties. In addition in the welding process, the smoke generated less, easy to control the welding pool and arc.
