Intelligent line welding method

Abstract

The invention relates to an intelligent line welding method. The intelligent line welding method comprises following steps: firstly, the welding line position is detected in real time; secondly, according to welding line position information, a motion trail of a welding gun is generated; and thirdly, according to the motion trail of the welding gun, the welding gun is driven to weld a welding line. Compared with the prior art, the welding line is scanned in real time, and operational data are processed; and the motion trail of the welding gun is generated while scanning is carried out. According to the intelligent line welding method, synchronous scanning and synchronous welding can be achieved, no pre-scanning time exists, and the welding efficiency is improved in a maximization manner; secondly, pipe bending, pipe height changes, and welding of complex pipe rows of a variable diameter part of a pipe can be processed, welding is completed at a time, and extra manual repairing welding is not needed.

Description

technical field [0001] The invention relates to a seam welding method, in particular to an intelligent seam welding method capable of real-time scanning and automatic seam welding. Background technique [0002] In the power plant boiler and pressure vessel industry, it is necessary to carry out production and processing for the welding of tubes and fins. like figure 1 As shown, it is a schematic diagram of the weld between the tube and the fin. Among them, the gap between the two pipes is the weld A that needs to be welded. [0003] However, during the welding process of the existing machine welding equipment, the operator needs to observe the position of the weld seam all the time, and needs to manually adjust the welding torch in time and effectively, so that the welding torch can keep up with the welding seam track and ensure the welding quality. The manual observation of the weld track or the deviation of the weld cannot be accurately observed and predicted in advance...

AI Technical Summary

Problems solved by technology

The position of the welding seam and the adjustment of the welding torch during the welding operation can only be adjusted by manually observing the welding seam track and manually adjusting the welding torch fine-tuning cross mechanism. position, this adjustment method will lag and be inaccurate

[0007] 3. The sequence of each weld of the welded pipe row can only be manually moved by the workstation, and the welding sequence cannot be edited in advance

[0008] 4. 2 workstations require 2 operators to track and monitor in real time. It is necessary to manually adjust the adjustment handle of the welding torch and fine-tune the cross according to the actual welding seam position, so that the welding torch can reach the appropriate position, so that the workers are in a state of tension every minute and every second, and the load will increase significantly.

[0009] 5. The electrical control of the existing welding equipment is based on the PLC core, which cannot achieve precise positioning control, and the error is large; the product CAD graphics import function cannot be realized
