Problems solved by technology
[0004] Aiming at the deficiencies of the prior art, the present invention provides an auxiliary internal lighting system for automatic identification of axial welds of straight seam pipes. Solved the problem that when the structured light method is used to identify the weld seam of a straight seam pipe with an extremely smooth surface, the recognition effect is poor due to the extremely weak scattered light on the surface of the pipe

The invention discloses an auxiliary internal lighting system for identifying an axial weld joint of a straight seam pipe and a welding method. A main supporting cavity is formed in the middle of a main supporting frame; a cooling water circulating pipeline is arranged on the back face of the main supporting frame; compressed air blowing pipes are arranged on the front face and the back face of the main supporting frame; an LED (Light Emitting Diode) light source is arranged at one end of the main supporting frame; and a transparent window is arranged above the LED light source. The internal lighting system extends into a position below the weld joint from one side where a metal plate begins to curl; a plate rolling roller is rotatably arranged on the side face of the metal plate; an industrial camera is fixedly arranged above the weld joint; a welding pool is arranged on the weld joint; a movable welding head is arranged above the weld joint; and a coarse locating column is fixedly arranged at the rear end of the internal lighting system. The differentiated LED light source in the system can be selected to be lightened according to the radiation spectrum condition of an actual welded material, and is matched with a corresponding optical filter on the industrial camera for use.
Description
Technical field[0001]The invention relates to the technical field of laser welding, in particular to an auxiliary internal lighting system and a welding method for identifying the axial welding seam of a straight seam pipe.Background technique[0002]Straight-seam metal pipes are widely used in tap water, petrochemical, agricultural, and electric power fields due to their excellent cost performance. They are a common engineering material in industrial applications. Straight seam metal pipes are generally formed by crimping and welding metal plates, so the welding process directly affects the quality and production efficiency of the straight seam pipes. When welding, the metal plate curling is a gradual process. Because the welding head (welding gun or laser welding head, etc.) is fixed, in order to make the welding seam just below the welding head, it needs to gradually change with the seam during the metal plate curling process. Small and set several positioning columns from thick to...
