The invention provides a continuous splicing method for aluminum alloy sheets. The continuous splicing method for the aluminum alloy sheets comprises the following steps that S1, a transfer machine conveys the sheet tail of the first aluminum sheet into the edge milling area, and a milling cutter is used for performing edge milling treatment on the sheet tail of the first aluminum sheet; S2, the transfer machine conveys the sheet head of the second aluminum sheet into the edge milling area, and the milling cutter is used for performing edge milling treatment on the sheet head of the second aluminum sheet; S3, the position of the first aluminum sheet and the position of the second aluminum sheet are adjusted through the transfer machine, and the sheet tail of the first aluminum sheet and the sheet head of the second aluminum sheet coincide in the welding area, a welding lead plate is placed, and friction stir welding connection is conducted on the first aluminum sheet and the second aluminum sheet through a stirring tool; S4, the welding lead plate is removed through the milling cutter; and S5, the steps from S1 to S4 are conducted repeatedly with the spliced aluminum sheets as a new first aluminum sheet and a newly added aluminum sheet as a new second aluminum sheet. By adoption of friction stir welding, the problems that electric-arc welding has a great number of defects and low rate of finished products are effectively solved; and high-efficiency friction stir welding continuous splicing of the aluminum alloy sheets is achieved based on the automation technology.
Description
technical field [0001] The invention relates to the field of metal welding, in particular to a continuous splicing method of aluminum alloy plates. Background technique [0002] Aluminum alloy sheets are widely used in aerospace, aviation, transportation, electric power and other fields. Since the aluminum alloy sheets produced by metal material factories have certain specifications, when aluminum alloy sheets larger than the established specifications are needed in production, it is necessary to check the aluminum alloy sheets. Splicing is carried out, and under some working conditions, multiple splicing is required to meet the requirements. The most commonly used method in splicing aluminum alloy sheets is arc welding. Arc welding is used for splicing aluminum alloy plates. It is necessary to open a welding groove on the edge to be welded. During the welding process, solder needs to be filled. The welding process is complicated and the production efficiency is low. The...
