the additive manufacturing gas protection sealing method comprises the following steps:
step one: moving the workbench (4) to a position bench worker operation origin a;
step two: accurately mounting a blank or a tool waiting for material addition or welding on a workbench (4) and ensuring that the blank or the tool does not interfere with a sealing cover 1, a movable laser cladding head or a movable welding clamp (100) in the moving process;
step three: moving the workbench (4) to a position sealing preparation point c to prepare for sealing of the sealing door 3;
step four: closing the sealing door (3), moving the workbench (4) to a sealing origin b after the sealing door (3) is closed, enabling a first sealing adhesive tape (60) on the primary sealing movable plate (6) to contact and extrude the sealing door (3), extruding a conical sealing thread adhesive head (7) into a conical hole (61), radially sealing the screw rod (12), and enabling a gas system to work through a gas inlet and a gas outlet to realize construction of an indoor environment atmosphere;
step five: the movable laser cladding head or the movable welding tongs (100) starts to process blanks needing material addition or welding according to an editing program;
step six: after the movable laser cladding head or the movable welding tongs (100) finish machining the blank, opening a gas system to start pressure relief, wherein the environmental atmosphere in the reduction cabin is the same as the outside;
step seven: moving the workbench (4) to a sealing preparation point c, separating the primary sealing movable plate (6) from the sealing door (3), and preparing for opening the sealing door (3);
step eight: after the sealing door (3) is opened, the workbench (4) is moved to a bench worker operation origin a;
step nine: carrying out bench work operation on the machined surface of the machined blank;
step ten: repeating the work of the third step to the seventh step after the bench work operation is finished, repeating the eighth step to the ninth step if the bench work operation is performed after the material addition or the welding is finished, and directly performing the eleventh step after the eighth step if the bench work operation is not required to be continued;
step eleven: after all the working procedures are completed, the workbench (4) is moved to the bench worker operation origin a to take out and unload the parts, and other parts are waited to be installed for processing.
