Welding preheating temperature intelligent measurement and control system

Abstract

The invention relates to a welding preheating temperature intelligent measurement and control system. A sensor module acquires temperature data in a certain area nearby a preheating point under the control of a main control and display module, and transmits the acquired temperature data signals to the main control and display module; the main control and display module calculates thermal imaging pictures in a generation area of the acquired temperature data and performs temperature field calculation on the thermal imaging pictures; after automatic judgment of a heating source, welding seam temperature and preheating temperature data, the main control and display module outputs a control signal to a relay module; a valve of an external heating source is controlled by virtue of the relay module to ensure that the preheating temperature is stabilized in a certain set temperature range; the main control and display module outputs a control signal to a driving module and a laser by virtue of a remote controller; the driving module drives a stepping motor to drive a movable bracket to move freely; and the movable bracket is positioned nearby the welding preheating point by virtue of the laser. The system can automatically identify a real preheating temperature so as to improve the welding quality, and has important significance for energy conservation and emission reduction.

Description

technical field [0001] The invention relates to a detection system, in particular to an intelligent measurement and control system for welding preheating temperature. Background technique [0002] The welding industry is developing very rapidly, and the automation level in various industries has also been significantly improved. Arc welding robots, spot welding robots, robot automatic production lines, etc. have been widely used in automobile production. However, major equipment industries such as boiler factories have a low level of automation because of the characteristics of traditional technology dominance, large scale, high investment costs for transformation, maintenance of the overall situation, and difficulty in transformation. The detection of the preheating temperature involved in the welding process basically follows the traditional method of manual recording. However, with the continuous deepening of industrial society, this status quo must be changed. While i...
