Problems solved by technology

[0002] At present, in the process of welding large-scale, medium-sized, super-large and extra-large construction machinery large-scale structural parts, due to various factors such as large-scale structural parts of construction machinery, large tonnage, long weld seams in the welding area, and various weld forms, etc. Influence, it is more difficult to control the welding quality in the welding process, however, the welding quality will directly affect the overall quality of the product
[0003] In particular, the automatic welding production line for large-scale structural parts of construction machinery usually debugs the welding process parameters and performs trial operation for the product before welding the product, which inevitably consumes preparation time for product welding, labor input and materials. , which will greatly restrict the switching efficiency of the production line for welding operations of various types and small batches of products
The main reason is the lack of on-line monitoring of welding quality and welding seam forming control equipment and related methods for the automatic production process of large-scale structural parts of construction machinery.

Abstract

The invention discloses an on-line monitoring system and method for a weld pool dynamic process. The on-line monitoring system for the weld pool dynamic process comprises an integrated control center, a sensing detection subsystem, a motion control subsystem, an expert database, a welding process control subsystem and a data transmission interface. The integrated control center is used for receiving data information, sending motion control instructions, welding process control instructions and data and reading instructions. The sensing detection subsystem is used for acquiring weld pool image information, process information, acoustical signals and temperature. The motion control subsystem is used for accomplishing weld seam tracking, welding gun height adjustment and speed control. The expert database is used for storing welding process control parameters, motion control parameters and sensing detection information. The welding process control subsystem is used for achieving control on welding current, arc voltage and speed. The data transmission interface is used for achieving data communication. The on-line monitoring method adopts the monitoring system to carry out on-line monitoring. The on-line monitoring system and the on-line monitoring method for the weld pool dynamic process have the advantages of being high in reliability, highly integrated in function and the like.

Description

technical field [0001] The invention belongs to the technical field of automatic welding monitoring of large structural parts of construction machinery, and more specifically relates to an online monitoring system and method for the dynamic process of a welding pool. Background technique [0002] At present, in the process of welding large-scale, medium-sized, super-large and extra-large construction machinery large-scale structural parts, due to various factors such as large-scale structural parts of construction machinery, large tonnage, long weld seams in the welding area, and various weld forms, etc. It is difficult to realize the welding quality control in the welding process. However, the welding quality will directly affect the overall quality of the product. [0003] In particular, the automatic welding production line for large-scale structural parts of construction machinery usually debugs the welding process parameters and performs trial operation for the product ...
