A handheld pressure vessel welding seam defect detection device comprises an equipment support, and a line laser module used for irradiating a welding seam, a camera module used for shooting the welding seam and a laser radar sensing module used for measuring the diameter of a pressure vessel are fixedly arranged on the equipment support. The line laser module, the camera module and the laser radar sensing module are jointly connected with a central processing module. The equipment support is further fixedly connected with a positioning mechanism, and the positioning mechanism is used for determining the relative position of the equipment support and the pressure container. According to the handheld pressure vessel weld defect detection device provided by the utility model, the laser radar sensing module is used for measuring the diameter of a pressure vessel, so that the effective measurement of the diameter under the condition of complex surrounding environment is realized, and the detection precision is im
