A monitoring method for a welding device

Abstract

The invention relates to a monitoring method for a welding device. The monitoring device includes a fixed arm, a displacement sensor is fixed at the front end of the fixed arm, and two sets of push rods are arranged side by side on the shift sensor. The rear end of the fixed arm is fixed with a temperature measuring probe, the middle of the fixed arm is equipped with a follow-up mechanism, a reducer, and a servo motor, and a welding torch is fixed on the follow-up mechanism. The reducer is respectively connected with the rotation of the follow-up mechanism and the servo motor The monitoring device also includes a control device, and the control end of the control device is respectively electrically connected to the displacement sensor, the temperature measuring probe, and the encoder of the servo motor. The monitoring method of the welding device of the present invention detects the position of the weld seam of the welding workpiece before welding; welds in an "S" shape to increase the welding saturation; and detects the temperature of the welding workpiece in real time.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a monitoring method for a welding device. Background technique [0002] Welding, that is, welding, is a manufacturing process and technology that melts welding materials by heating, high temperature or high pressure to combine the objects to be welded. The energy of welding includes: gas flame, electric arc, laser, electron beam, friction and ultrasonic, etc. During the welding process, the control of the welding temperature (preheating temperature, interlayer temperature, postheating temperature) is very important, and the welding temperature factor plays a decisive role in the quality of the weld. At the same time, the fullness of the weld and whether it is welded are also important technical indicators in the welding process. [0003] At present, the working mode of the welding device / equipment is: fix the welding torch, realize welding by rotating and translating the weldi...

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] Poor real-time detection of welding temperature
