The invention discloses a method for reducing deformation quantity caused by PIN detection and a device for detecting welding quality, and particularly relates to the technical field of welding quality detection. In the first process, the detection head detects the welding quality of the PIN needle in the first direction to generate deformation; in the second process, the detection head detects the welding quality of the PINs in the second direction; the first direction and the second direction are opposite to each other; the second process is provided with a correction model, and the correction model is used for correcting deformation generated in the first process; the correction model is used for acquiring or predicting the deformation quantity, and the deformation quantity correction model takes the generated deformation quantity displacement as an input variable and takes the correction displacement as an output to correct the generated deformation; according to the invention, the deformation quantity an
