The present invention provides an assistant coating TIG fusing-brazing method suitable for aluminum/steel dissimilar alloy butting. In the assistant coating TIG fusing-brazing method, a TIG electric arc is used as a heat source, and an assistant coating and joint groove design and a welding technology are used. In a welding process, electric arc heat firstly enables an assistant coating to fuse to form a liquid film at a steel groove surface; the TIG electric arc is covered on welding wires to directly heat the welding wires and a fused bath, while not to directly heat steel plates, so a fused phenomenon is avoided to be generated on steel surfaces; the welding wires are fused rapidly to moisten and spread rapidly on the steel groove surface under the function of the assistant coating; the welding wires are fed continuously to be fused to fill welding seams gradually; and meanwhile the electric arc walks rapidly, and brazing alloy spreading is stopped when the heat source is moved away. The welding process is stable, and butting joints of aluminum/steel dissimilar alloy TIG fusing-brazing with good formation are obtained.
