Welding correction method, welding correction equipment and readable storage medium

Abstract

The invention provides a welding correction method and device and a computer readable storage medium, and the welding correction method comprises the steps that original welding information is determined; based on the original welding information, a first base material and a second base material are welded according to a test path, so that a fusion depth layer is formed between the first base material and the second base material; determining connection information between the first base material and the second base material based on the fusion depth layer; based on the connection information and the original welding information, welding correction information is determined, a test welding path is determined through the original welding information, a first base material and a second base material are welded according to the test welding path to form a fusion depth layer, connection information between the first base material and the second base material is obtained according to the fusion depth layer, and the connection information between the first base material and the second base material is obtained. And acquiring welding correction information according to the connection information and the original welding information, and correcting the original welding path by using the welding correction information to eliminate virtual welding between the first base material and the second base material so as to enhance the welding strength between the first base material and the second base material.

Description

technical field [0001] The present application relates to the technical field of welding, and in particular, to a welding calibration method, a welding calibration device and a readable storage medium. Background technique [0002] As shown in Fig. 1(A) and Fig. 1(B), Fig. 1(A) is a top view of a workpiece in the prior art after welding, and Fig. 1(B) is a section based on a welding spot in Fig. 1(A) Sectional view of the workpiece. The first metal piece 10a is fixedly connected to the second metal piece 20a to form a workpiece including welding. Generally, the operation process of welding the first metal piece 10a to the second metal plate 20a is as follows: the laser goes to the first metal piece 20a in a circular welding path. A metal piece 10a emits a laser, the laser fuses the first metal piece 10a and the second metal plate 20a to form a penetration 40a, and a welding spot 30a is formed on the surface of the first metal piece 10a to realize the connection. Generally,...

Problems solved by technology

Usually, since the welding path of each welding point is circular, the starting point of welding coincides with the end point, but in the welding process, the light output power required for welding to form a penetration depth 40a between the first metal piece 10a and the second metal plate 20a reaches preset power, and it takes a certain amount of time for the light output power to reach the preset power, and at the starting point of welding, part of the light output energy is absorbed by the first metal piece 10a in the cooling state, resulting in the virtual welding area 50a often appearing in the initial stage of welding, The penetration depth 40a under the multiple welding spots 30a has a virtual welding area 50a, which leads to weak bonding strength between the first metal piece 10a and the second metal plate 20a, and the pulling force is unstable, and it is easy to fall off during the impact process
