Problems solved by technology
When the seam welding machine performs seam welding, due to factors such as the material of the fuel tank, the adjustment of the welding machine, and the proficiency of manual operation, sometimes there will be seam welding quality problems, and leakage will occur at the weld seam of the tank, and the fuel tank manufacturer, here After the process is over, there is no inspection method, and the fuel tank is buried in water as a whole after all the production processes of the fuel tank are completed, and the gas is inflated to check for leakage. If leakage is found at the welding seam at this time, the fuel tank will be defective and must be reworked Repair welding requires a lot of work, and it is not easy to stabilize the production quality of the fuel tank

Description
technical field [0001] The invention belongs to the field of machinery, and in particular relates to an automobile fuel tank seam welding inspection machine. Background technique [0002] Automobile fuel tanks are used to hold fuel for automobiles. Therefore, in the production of automobile fuel tanks, the leakage rate of fuel tanks is an important indicator to measure the quality and safety of fuel tank products. At present, the fuel tanks of passenger cars and trucks with a fuel tank volume greater than 60 liters are all made of metal materials. First, they are formed by rolling a metal sheet, and then longitudinally seam-welded by a seam welding machine to form a box body. The tank lid is then seamed to form the tank. When the seam welding machine performs seam welding, due to factors such as the material of the fuel tank, the adjustment of the welding machine, and the proficiency of manual operation, sometimes there will be seam welding quality problems, and leakage wil...
