Monitoring method of welding device

Abstract

The invention relates to a monitoring method of a welding device. A monitoring device comprises a fixed arm, a displacement sensor is fixedly arranged at the front end of the fixed arm, two sets of ejector rods are arranged on the displacement sensor side by side, ejector heads of the ejector rods abut against two sides of the welding position of a welded workpiece, a temperature measuring probe is fixedly arranged at the rear end of the fixed arm, a follow-up mechanism, a speed reducer and a servo motor are arranged in the middle of the fixed arm, a welding gun is fixedly arranged on the follow-up mechanism, and the speed reducer is meshed with rotating ends of the follow-up mechanism and the servo motor respectively; and the monitoring device further comprises a control device, and a control end of the control device is electrically connected with the displacement sensor, the temperature measuring probe and an encoder of the servo motor. The invention discloses the monitoring method of the welding device. The method comprises the following steps: detecting the position of a welding seam of the welded workpiece before welding; carrying out S-shaped welding, so that the welding saturation is improved; and detecting the temperature of the welded workpiece in real time.

Description

technical field [0001] The invention relates to the technical field of welding, in particular to a monitoring method of a welding device. Background technique [0002] Welding, that is, welding, is a manufacturing process and technology that melts the welding material by heating, high temperature or high pressure, and combines the welded material. The energy of welding includes: gas flame, arc, laser, electron beam, friction and ultrasonic. In the welding process, the control of welding temperature (preheating temperature, interlayer temperature, post-heating temperature) is very important, and the welding temperature factor has a decisive influence on the quality of the weld. At the same time, the fullness of the weld and whether it is false welding is also an important technical indicator in the welding process. [0003] At present, the working method of the welding device / equipment is as follows: fixing the welding torch, realizing welding by rotating and translating th...

AI Technical Summary

Problems solved by technology

[0004] 1. After the welding workpiece is fixed on the welding device, the position detection of the welding workpiece on both sides of the weld is not carried out;

[0005] 2. Although the fixed welding torch can increase the stable distance between the welding workpiece and the welding torch, it cannot achieve the fullness between the hot-melt welding material and the welding seam during the welding process;

[0006] 3. Poor real-time detection of welding temperature
