Described herein is a device and a method for providing inertia gas when workpieces are brazed. In one aspect, the device for supplying the inertia gas to atmosphere above a welding material storage tank. The device comprises a base part, a pipeline and one or more support legs; the base part comprises an inner space which is in fluid communication with an inertia gas source, the pipeline is provided with an inner space and comprises one or more via holes through which the inertia gas can flow, each of the one or more support legs comprises an inner space which is in fluid communication with the inner space of the base part and the inner space of the pipeline, the one or more support legs extend upward along the lengthwise direction from the base part, the pipeline is elevated to be above a surface of a melted welding material accommodated in the welding material storage tank, the inertia gas passes through the base part and enters the inner space of the pipeline after running upward through the one or more support legs, and finally the inertia gas flows out through one or more via holes of the pipeline.
