description	The invention belongs to the technical field of aero-engine welding, and relates to an argon arc welding method for a low-alloy high-strength steel end part and a thin-wall rod and pipe type part assembly, aiming at the argon arc welding of the low-alloy high-strength steel thin-wall rod and pipe type part assembly (the wall thickness is less than or equal to 2mm) and the end part. In order to solve the problems of excessive weld metallurgical defects, low hardness of a heat affected zone, out-of-tolerance welding deformation and the like caused by structural configuration of the components, the mode of no beveling, no welding wire filling and complete automatic argon arc welding is adopted, and a part self-locking bottom structure is adopted, so that the assembly clearance of to-be-welded parts of the components is ensured, and the part offset is reduced; and automatic argon arc welding process parameters are precisely regulated and controlled, heat exchange and cooling of the copper sleeve are assisted, and
