Embodiment Construction

[0022] Below in conjunction with embodiment and with reference to accompanying drawing, the utility model is described in further detail.

[0023] The present invention consists of a spiral tube submerged arc welding machine 2 placed in a spiral tube 1, a temperature field sensor 4, a control box 9 and an industrial control computer 8. The temperature field sensor 4 installed on the back of the weld in the spiral tube 1 is controlled by an infrared filter. Composed of light sheet 3 and image charge coupled device 5, weld seam tracking and penetration integrated intelligent control module 10 and interface drive circuit 12 are installed in control box 9, image acquisition card 7 and The input / output card 6 is designed with a temperature field welding seam and penetration feature identification information processing module 11 in the industrial control computer 8 .

[0024] The temperature field weld seam and penetration feature recognition information processing module 11 is com...

Abstract

The invention discloses a kind of integrated intelligent control system for welding seam tracing and penetration in spiral tube, which includes spiral tube submerged arc welding machine, the character lies in: it also includes temperature field sensor, control box, and industrial control computer, there sets welding seam tracing and penetration integrated intelligent control model and interface driving circuit in the control box, there designs a temperature field welding seam and penetration characters identification information processing model in the industrial control computer. The invention only needs a sensor in order to extract the bias and penetration information of welding seam, which uses seam identification space frequency domain method to identify welding seam, uses penetration constant temperature line width method to identify the penetration degree. The invention also creates constant temperature line width which shows the penetration degree indirectly and reverse transmission nerve network for penetration degree. The invention realizes the automatic tracing of welding seam, completes the intelligent control for welding seam tracing and penetration.

Description

technical field [0001] The invention relates to welding automation technology, in particular to an integrated intelligent control system for welding seam tracking and penetration in a spiral tube. Background technique [0002] Welding is a process with relatively high labor intensity, serious impact on workers' health, and relatively low automation level. Therefore, welding automation has always been the direction that welding technicians are committed to. In the welding process, two key technologies affecting automation are seam tracking and penetration control. For seam tracking, there are currently sensing technologies such as laser images and rotating arcs. The former is an additional sensor, which is relatively expensive and has problems ahead of time, and requires a bevel; the latter realizes the combination of the welding torch and the sensor. Ahead of the problem, but also need to have a groove. For penetration control, there is a method of extracting penetration i...
