Abstract

The invention discloses a method for determining the deviation position of a welding seam, a welding method and a related device. The method for determining the deviation position of the welding seam comprises the steps: determining first position coordinates of a standard workpiece in a preset coordinate system; determining second position coordinates of a to-be-welded workpiece in the preset coordinate system; calculating homogeneous transformation matrixes of the first position coordinates and the second position coordinates; and according to third position coordinates of a first welding seam of the standard workpiece and the homogeneous transformation matrixes, conducting calculation to obtain fourth position coordinates of a second welding seam of the to-be-welded workpiece. In this way, the time for determining the position coordinates of the welding seam is shortened, and the subsequent welding efficiency is improved.

Description

technical field [0001] The present application relates to the field of welding technology, in particular to a method for determining a weld offset position, a welding method and related devices. Background technique [0002] In welding applications, due to problems such as poor consistency of fixtures and welding workpieces, the actual weld position of the workpiece is inconsistent with the taught weld position, and such workpieces cannot be mass-produced by robot welding. [0003] In related technologies, the search for the offset position of the welding seam is to pass low pressure to the welding wire. When the welding wire touches the workpiece, it will be turned on, and the position where it hits the workpiece will be recorded. According to different situations where the workpiece may be offset, the number of points touched by the welding wire It varies, up to six points may be touched. [0004] The disadvantage is that the accuracy of calculating the offset position is...
