PURPOSE: An aluminum product welding method using high-frequency induction coils is provided to weld aluminum without damage to a base material by directly heating the edge and surface of the base material in a preheating unit and filler metal in a heating unit. CONSTITUTION: An aluminum product welding method using high-frequency induction coils comprises the steps of: winding one end of a high-frequency induction coil into the shape of a cochlea from outside in while the other end into the shape of a cochlea from inside out so that preheating units(150a,150b) are located outside and a heating unit(170) is located in the right center and preheating first and second base materials(200,300) to a predetermined temperature while heating a filler metal(400) placed in a weld zone of the first and second base materials.
