The invention discloses a machining technology of a redriving aluminum alloy pan, comprising the following steps of: (1) stretching for the first time; (2) compounding a redriving sheet on the pan bottom; (3) stretching for the second time; (4) carrying out the subsequent treatment, wherein the step (2) comprises the following specific steps: (2.1) preliminarily welding the redriving sheet: taking the redriving sheet, fixing the redriving sheet on the lower surface of the pan body in a spot welding way and subjecting the lower surface of the redriving sheet to the frosting and sand blasting; and (2.2) redriving process: enabling the bottom of a pan body to face upwards and placing the pan body on a high-frequency heater in a back buckling way; starting the high-frequency heater to allow the temperatures of the redriving sheet and the bottom of the pan body to be up to 450-550DEG C, lasting for 5-60 seconds; and enabling the bottom of the pan body to face upwards and placing the pan body on a redriving machine for redriving so as to ensure that the redriving sheet is firmly combined with the pan body. Compared with the prior art, the invention has the advantages of simple process, low requirement on the equipment and stable quality on products. The prepared products have the advantages of high heat conductivity, energy source saving, light pan body, convenient use, easy cleaning, no stick on the bottom and oil saving.
