The invention relates to the technical field of welding, in particular to a welding tool for a compressor dispenser assembly. The welding tool for the compressor dispenser assembly comprises an induction welding device, wherein the induction welding device comprises an induction coil; the induction coil comprises a first coil part and a second coil part; the first coil part and the second coil part can be arranged in an opening and closing way; when the first coil part and the second coil part are closed, a round structure is formed. A heating source adopts induction brazing instead of flame brazing, so that the problem of unstable heating temperature caused by fuel gas fluctuation is solved; meanwhile, an opening and closing induction coil structure is adopted, and the two coil parts are combined into a whole during welding and are stretched automatically after welding, so that the heating uniformity is enhanced, and the welding efficiency is increased; moreover, dazzling light, smoke dust and high noise generated by flame combustion are eliminated, the brazing operating environment is improved remarkably, the potential safety hazard of gas explosion is eliminated, and environment-friendly brazing production is realized.
