The invention discloses a self-resistant electrically-heated incremental free bending forming clamp and forming method for an airplane profile, and the two ends of the airplane profile are clamped bythe clamp matched with the section of the profile correspondingly. The forming clamp and forming method is characterized in that an electrode connecting device is used for communicating with a copperelectrode plate embedded in the contact part of the clamp and the profile, so that the profile is self-resistant and electrically heated after being electrified, and a bending clamp and a fixing clampare driven by an industrial mechanical arm to carry out segmented torsion bending on the airplane profile until a space shape guide line of the airplane profile meets design requirements. According to the self-resistant electrically-heated incremental free bending forming clamp and forming method for the airplane profile, the deformation period of bending forming is short, and the efficiency is high; in each incremental st
