Promote transformation and upgrading to make the future of laser+construction machinery possible（2）
(4) Multi head large cross-section laser cutting equipment is mainly used to meet the requirements of laser batch processing under the premise of large-scale manufacturing. (5) The automatic production line of laser cutting processing mainly solves the problems of batch production and labor saving. From unloading to completion, it has entered a new unmanned intelligent manufacturing mode, including automatic storage, automatic cutting, automatic carving, automatic sorting and assembly, automatic transportation and other full process automatic production lines. (6) Three dimensional laser cutting technology is usually used for processing after body assembly, upper cover guide rail hole, antenna mounting hole, wheel mudguard shape correction, etc. (7) Laser welding or laser hybrid welding of transmission gears of construction vehicles has a narrow welding heat affected zone with high strength. The depth and width of the weld may exceed 10:1. The mechanical property of the weld is h...
