Abstract: The present application provides a welding assembly and a battery module. The welding assembly includes: a first weldment; and a second weldment, welded and fixed with the first weldment to form a welding seam; where, at least one side of the welding seam is provided with an exhaust channel; and the exhaust channel is located between the first weldment and the second weldment. In the present application, an exhaust gas generated during welding can be discharged from the exhaust channel to prevent it from entering the welding seam to reduce the strength of the welding seam.
