Car welding is one of the most key link for the vehicle manufacturing, 72 pieces of special aluminum alloy sheet was seamless welded together. Automatic welding robot to move forward at a speed of 70 centimeters per minute on average, a list of all 8 high-speed locomotive car welding length of 18.4 kilometers, the vast majority of them are done by automatic machine, ensure the precision of welding to a great extent. Production technology of bogie is another core secrets in vehicle production, its production quality, directly affect the safety of the high-speed locomotive, especially its core parts, axle production of hollow axles are precisely processed and precision error is strictly under control in the 0.1 mm. |
