Abstract

The invention discloses a welding method for identifying a welding seam. According to the welding method for identifying the welding seam, the to-be-welded workpiece is scanned through the welding seam sensor to obtain the plane coordinates of the welding seam, and welding seam welding can be accurately conducted; when the plane coordinate of the welding seam is inconsistent with the sensing center coordinate of the welding seam sensor, the friction stir welding drill bit and the welding seam sensor can be controlled to generate relative angular displacement or the welding seam sensor is further controlled to move around the axis of the welding seam sensor until the plane coordinate of the welding seam is consistent with the sensing center coordinate of the welding seam sensor; and the welding accuracy and efficiency are further improved.

Description

technical field [0001] The invention relates to the technical field of welding, in particular to a welding method for identifying a weld. Background technique [0002] The friction stir welding device is a technology that uses the heat generated by the friction between the high-speed rotating welding tool and the workpiece to be welded to melt the material of the workpiece to be welded, and form a weld under the extrusion of the welding tool. The friction stir welding device can complete the welding of long welds, large sections and different positions at one time, with low residual stress and low cost. However, the friction stir welding device in the prior art is difficult to identify the weld seam and the identification efficiency is low for the large plate weldment with small batch size and specific texture characteristics with curved weld seam. [0003] Therefore, in view of the above technical problems, it is necessary to provide a welding method that can cope with the...
