All-position automatic welding system

Abstract

The invention discloses an all-position automatic welding system, mainly comprising a welding machine head module, a central controller, a welding power supply module, a power adapter and a remote control operation module, wherein the welding machine head module transmits the position information of a current welding torch to the central controller; the central controller carries out operation processing on the data; the central controller gives a corresponding welding instruction according to the result of the current position operation processing; and the power adapter controls the output of the welding power supply according to the welding instruction of the central controller and obtains a driving signal to control the movement of the welding torch, and the real-time control on the welding seam tracking process is realized. Corresponding welding specifications are automatically matched according to the different positions of the welding torch in the welding process; the position of the welding torch relative to the welding seam is detected in an online manner in the welding process, so that the automatic welding seam tracking of the welding torch is realized; and the welding quality is high, the speed is high, efficient automatic welding equipment for field long-distance transport pipeline is realized, and the all-position automatic welding system is adaptive to various field environments.

Description

technical field [0001] The invention relates to the technical field of detection and automatic control, is specifically applied in welding process control and automatic tracking of welding seams, and is suitable for the construction of various field long-distance pipelines. Background technique [0002] At present, many construction units in the construction of field long-distance pipelines use manual semi-automatic welding. The investment in semi-automatic welding equipment is small, and the composition of personnel is flexible. However, the number of welds that can be achieved per day is 30-40, and the welding quality is affected by individual welders. Quality has a greater impact. And this automatic welding equipment can achieve 80-100 welds per day, and the welding quality can be effectively guaranteed. However, due to the influence of various factors, the actual welding conditions often change, resulting in a decline in welding efficiency and welding quality or even fa...
