Adaptive control plane class automatic welding machine is a high degree of automation of welding equipment. It is equipped with sensors and electronic detection circuit automatic welding machine manufacturers, the trajectory of the weld seam tracking loop automatic guidance and automatic welding machine, some devices can also achieve closed-loop control of the welding parameters such as welding current, welding voltage, welding speed, the whole welding process automatically according to the procedure and process parameters set in advance. For example, larger cylinder or tube-type parts, electrical control system generally consists of: relay, PLC programmable logic controller, microcontroller, numerical control systems, computer control. In the welding site, due to welding spatter and more complex electrical wiring water, electromagnetic interference, so the relay, PLC, CNC system most commonly used. Because both the relay and PLC functionality straight seam automatic welding machine, they can achieve programming control. With the advent of technology and the development of new products, and now the PLC also enables more complex functions, such as part of the CNC functions, such as circular interpolation and so on. So PLC control technology in automated welding machine has been the most widely used.
