Application and Value of Automatic Welding Equipment in Full Position Welding
First, the application of automatic welding equipment in all-position welding, the implementation of the welding components to take the spin-driven approach to the welding gun attitude flexible and reasonable changes in favor of all-position welding work. At the same time when driving the same welding executive components, but also reduce the motor power. In applications, it is best to install the sensor on the welding position to the final reduction shaft to detect the position of the welding torch. With this method of installation, the control accuracy obtained is relatively high. In addition, with the automatic welding equipment on this memory, part of the welding process parameters and weld tracking control program stored, the welding process parameters stored in the arc welding power supply, in order to make the arc welding power advantages Good play, through the cooperation between the two, effectively solve all kinds of quality problems that may appear in the automatic welding position.
Second, the torch drive by means of a stepper motor (stepper motor refers to the electric pulse signal into angular displacement or linear displacement of an open-loop control element stepper motor) to implement the drive, the motor can be Digital input pulse model for effective conversion, convert it into a rotary motion, the high accuracy of the components themselves, not only does not appear the drift problem, but also does not appear cumulative error and other issues. The application of this component in the all-position welding, not only does not make the speed change, while controlling the frequency signal is relatively stable, torch displacement is also more accurate.
Thirdly, in the all-position welding operation, the welding head and the arc welding power source are combined organically to not only achieve the purpose of automatic welding in all positions, but also to lower the automatic welding equipment price to a certain extent. In this way, not only automatic welding but also semi-automatic welding can be carried out with the aid of arc welding power sources and the use of semi-automatic welding guns.
