Automatic sensing and control method of friction stir welding trajectory for fillet joints

Abstract

The invention provides an automatic sensing and control method of friction stir welding trajectory suitable for fillet joints. The method firstly measures the welding seam data in real time by a data measurement module, and calculates the adjustment data of the stirring head according to the measured data by a data processing module. The mechanical control module implements the adjustment command of the stirring head, so that the process of welding fillet joints does not need manual adjustment. For straight right angle welds or arc right angle welds, the position of the stirring head can be automatically adjusted to complete the welding. The invention realizes the automatic welding of the friction stir welding fillet joint and the automatic adjustment of the welding track, and improves the welding production efficiency.

Description

technical field

[0001] The invention relates to the field of automatic welding of friction stir welding and the field of design of a static shoulder stirring head, in particular to an automatic sensing and control method of a friction stir welding trajectory suitable for fillet joints. Background technique

[0002] Production automation has always been the ultimate goal of continuous research and improvement of production equipment and production systems. As a new welding method, friction stir welding has attracted the attention of researchers at home and abroad. With the research on the structure of the stirring head and the welding process, it has been possible to weld Welds of various structures such as fillet joints, lap joints and spot welded joints.

[0003] However, in the current welding equipment, the machine tool type friction stir welding machine is mainly used. Machine-tool friction stir welding machines are capable of welding longer welds, but there are still p...
