The invention discloses a laser tailor-welded plate which comprises a first plated steel plate and a second plated steel plate. The thicknesses or strengths of the first plated steel plate and the second plated steel plate are different, and the first plated steel plate and the second plated steel plate are welded and connected through a laser tailor-welded technology. The invention also providesa laser tailor-welded plate thermal forming component which is obtained by carrying out hot stamping forming on the laser tailor-welded plate. The invention also provides a preparation method of the thermal forming component. The preparation method comprises the following steps: S1, fixing the two plated steel plates with different thicknesses or strengths on a laser tailor-welding machine througha welding fixture; S2, welding the two plated steel plates together by utilizing a laser tailor-welding technology to obtain the laser tailor-welded plate; and S3, performing hot stamping forming onthe laser tailor-welded plate to obtain the laser tailor-welded plate thermal forming component. By means of the laser tailor-welded plate and the application, the welding strength is improved, and the requirement that different parts of an automobile body have different strengths is met.
