Rigid welding equipment
Also known as primary automation equipment, most of them are designed according to the open-loop control principle. Although the equipment automatically completes the whole welding process, it can not carry out closed-loop feedback control for the fluctuation of parameters in the whole process, nor can it randomly correct the possible deviation.
2 adaptive control automatic welding equipment
It is a welding equipment with high degree of automation. It is equipped with electronic sensing circuit and sensor to automatically guide and track the weld track and implement closed-loop feedback control for main parameters. The whole welding process will be completed automatically according to the preset procedures and process parameters.
3 intelligent automatic welding equipment
It uses a variety of detection elements, such as visual sensor, touch sensor, auditory sensor and laser scanner, and carries out real-time identification, judgment, detection, calculation and automatic programming with the help of computer software system database and expert system. Storage of welding parameters and automatic generation of welding log files.
Composition of automatic welding equipment:
1. The output power and welding characteristics of the welding power supply shall match the recommended process method, and shall be equipped with an interface connected to the main controller.
2 wire feeder and its speed regulation control system for wire feeder with high speed control accuracy, the control circuit needs acceleration feedback.
3 welding head. Its motion mechanism is composed of welding head, welding head support frame, suspension trolley, etc., which is lower than the welding head mechanism, and its driving system needs to adopt servo motor with encoder.
4 traveling mechanism, such as welding roller frame, head and tail frame turnover machine, turntable positioner, etc. the movable traveling mechanism needs to be driven by servo motor.
5 main controller, also known as system controller, is mainly used for link control of various components of automatic welding equipment, control of welding program, setting, adjustment and display of main parameters of welding and expansion, fault diagnosis, man-machine dialogue and other control functions.
6 computer software. The software commonly used in the equipment includes programming software, function software, expert system and process method software.
7 wire feeding system circulating water cooling system flow recovery conveyor wire rack drag chain and cable hose mechanism structure design three parts electric control design and other auxiliary devices.
8 welding head tracking or guiding mechanism arc voltage automatic controller welding gun yaw and monitoring system.
