The invention discloses an intelligent
welding machine for the inner wall of a fuel cabin of an LNG ship, and relates to the technical field of
plasma intelligent
welding machines. The intelligent
welding machine comprises a linear track, connecting clamps between the track and a welding base material, an intelligent welding
machine body, a 3D visual tracker and the like. the automatic welding machine body is provided with a five-axis
servo gear motor linkage and corresponding movement track component (a
ball screw is used for transmission), a
laser sensor is used for measuring the height distance between the end surface of a welding gun and a
weld seam in real time, each connecting clamp is provided with a positioning clamping jaw, a movable clamping jaw, a push-pull type quick clamp body and a track connecting block, a 3D
visual tracking system is used for collecting the three-dimensional overall dimension of the
weld seam, analyzing the optimal walking
route in the
welding process and correcting the welding position and angle deviation during in the
welding process, a remote controller has the manual alignment and adjustment functions and the
remote operation function, and
plasma water-cooling welding application is mainly introduced for meeting the welding requirement of thin stainless
steel plates (stable welding performance and small deformation).
