What is the function of a shielding gas flowmeter?

The function of a shielding gas flowmeter is to control the amount of shielding gas flowing during the welding process. Shielding gas is critical in gas metal arc welding (GMAW) as it protects the molten weld pool from atmospheric contamination, which can negatively affect the quality of the weld. The flowmeter ensures that the gas is delivered at the correct flow rate, which is essential for maintaining optimal shielding and achieving good weld quality. Proper gas flow helps prevent issues such as porosity or oxidation, allowing for a cleaner and stronger weld. Adjusting and measuring the gas flow accordingly enhances the overall performance of the welding process.
