The invention discloses a welding quality control method and device for gas-tight seams. The method comprises the following steps: a welding process of an air spring support beam is determined according to requirements on gas tightness of seams, and the welding is performed according to the welding process; and after the welding of the air spring support beam is completed, two tests for gas tightness are performed on the air spring support beam, wherein the primary test for gas tightness is performed before accessory assembly of a bogie frame, and the secondary test for gas tightness is performed after completion of an anti-rust paint applying procedure. The device is used for carrying out the method. The welding quality control method and device for the gas-tight seams can improve the product quality of bogie welding components to reduce the production cost of bogies.
