The invention discloses a method for machining a porous-surface heat-exchange pipe for boiling heat-transfer equipment, aiming at providing a heat-exchange pipe and a machining method with the advantages of simple process, convenience for machining, no falling of a machined porous surface and capability of machining various complex structural forms. The method comprises the steps of: cutting an aluminum alloy sheet according to developed dimensions of a base pipe and a porous layer of a heat-exchange pipe respectively to obtain aluminum alloy sheets which are respectively used for machining the base pipe and the porous layer and have the same dimensions as the developed dimensions of the base pipe and the porous layer of the heat-exchange pipe; respectively evening out; placing the evened-out aluminum alloy sheet for machining the porous layer in the middle of a terrace die and a hollowing die, and punching the aluminum alloy sheet for machining the porous layer by using the terrace die and the hollowing die; superposing and thermally pressing a porous layer substrate and the evened-out aluminum alloy sheet for machining the base pipe so that the porous layer substrate and the evened-out aluminum alloy sheet for machining the base pipe are integrated; and then, machining the evened-out aluminum alloy sheet for machining the base pipe into a pipe shape, and welding both the machined aluminum alloy sheets to obtain the aluminum alloy heat-exchange pipe with the porous surface.
