In order to improve the laser utilization and automation of high power laser processing,a new three-working-position automatic laser welding control system was designed based on programmable logic controller and movement controller.By means of queue by turns and time sharing method to use the output laser,the universal saw blades,helical tooth saw blades and the bits can be welded simultaneously.Every working position can finish the manual debugger or execute the laser processing.And the processing laser power will be controlled independently by the working position.The production efficiency was improved 50% when the control system was used on welding production line. The universal saw blades,helical tooth saw blades and the bits in 115mm-600mm diameter and diamond drills in 20mm-250mm diameter can be welded in the system.Furthermore,the system has full diagnosis and warning functions.
