Abstract

The invention provides a welding method for a friction stir welding device of a storage tank of an aerospace vehicle. The friction stir welding device of the storage tank of an aerospace vehicle includes a friction stir welding head and a milling head. The method includes: step S1, respectively milling the barrel section of the storage tank and the part to be welded at the bottom of the tank through the milling head around the circumferential direction of the storage box to mill out a matching butt joint surface; step S2, milling the barrel section of the storage box and the The milled butt joint surfaces of the bottom of the tank are seamed, and the friction stir welding head is used to perform circumferential rotation welding around the circumferential seam of the storage tank. The method solves the problem that the accuracy of the device decreases after a long service time due to the large inertia caused by the synchronous rotation, and improves the practicability of the device.

Description

technical field

[0001] The invention relates to the field of friction stir welding, in particular to a welding method used in a friction stir welding device for a storage tank of an aerospace vehicle. Background technique

[0002] Friction stir welding technology has been hailed as the most creative invention in the past 30 years in the field of welding. It is a high-quality, efficient, green, low-cost, and low-distortion solid-phase welding method that completely solves the problems caused by welding of various non-ferrous metals. A series of problems in the future, and gradually replace the fusion welding method, has been widely used in aviation and aerospace fields.

[0003] At present, the conventional friction stir welding equipment for storage tanks in China is in the form that the head of the friction stir welding machine is fixed, and the storage tank to be welded is moved and rotated. This type of equipment is acceptable for welding small-sized products or storage ...
