Efficient,high-precision,green laser welding technology has become one of the mainstream ways of structural parts manufacturing.The successful introduction of laser welding technology in the manufacture of medium and thick plate members has become an important symbol of technology leadership in the construction machinery industry.Due to the characteristics of construction machinery manufacturing mass and low processing accuracy requirements,it is difficult to introduce laser welding technology into the manufacturing application of medium thick plate members.This paper summarizes the characteristics of typical construction machinery structural parts,and summarizes the key problems to be solved in the process of technology introduction from three levels:process,equipment and production line.According to the engineering development experience,the key points of laser welding technology and complete set of equipment development of medium and thick plate members are clarified,the introduction paradigm of laser welding technology to the general manufacturing of construction machinery structural parts is proposed,and based on the paradigm,the work idea of comprehensive introduction of subsequent processes is proposed,and four basic works are summarized.
