Embodiment Construction

[0058] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention. , not all examples. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0059] First, the technical terms involved in the present invention will be explained.

[0060] Welding wire refers to the wire that is filled in the gap on the weldment due to the heat of the arc. The material of the wire is usually the same as the material of the weldment.

[0061] The molten pool refers to the part of the base metal that is melted into a pool-like shape due to the heat of the arc. The part of ...

Abstract

The invention provides a fusion width control method, device and system, a medium and a product. The method comprises the steps that pre-stored welding parameters corresponding to the current moment are obtained; determining a control current value at the current moment according to the welding parameters and a pre-stored expected fusion width at the next moment; and the welding system is controlled to weld the gap according to the control current value at the current moment, so that the difference value between the weld back fusion width of the gap at the later moment and the expected fusion width at the later moment is not larger than a preset threshold value. The invention provides a fusion width control method, equipment, a system, a medium and a product, which are used for improving the welding quality and realizing real-time control on the fusion width of the back surface of a welding seam in the welding process.

Description

technical field [0001] The invention relates to the technical fields of sensing technology, nonlinear control, simulation technology, welding and the like, in particular to a fusion width control method, equipment, system, medium and product. Background technique [0002] Welding (also known as welding) is a manufacturing process and technique for joining metals or other thermoplastic materials (eg, plastics) using heat, high temperature, or high pressure. With the development of science and technology, in order to improve welding efficiency and save labor, intelligent and automated welding came into being. [0003] At present, in intelligent and automated welding, the robot usually performs welding operations on the gaps on the weldment according to the received motion behavior instructions. During the welding operation of the robot, it is impossible to control the fusion width on the back of the weld in real time. When the heat dissipation conditions of the weldment / the g...
